The life-changing flying eye hospital treating blindness across the globe – The Guardian

Friday, May 12th, 2017

In Kitwe, the second largest city in Zambia, young mother Verah is carrying her one-year-old daughter, Racheal, into the consultation room at the eye annexe. The only dedicated paediatric eyecare centre in the country, the Kitwe annexe also attracts patients from neighbouring Angola and Congo. Racheal is here for surgery to remove the bilateral cataracts that prevent her from seeing.

A few months after Racheal was born, Verah noticed that something didnt seem right with her vision. I would move my hands in front of her face but she would not react. I would move things past her eyes but she would not follow them, she explains.

The team of nurses, anaesthetists and paediatric ophthalmologists treating Racheal have been trained and are being continually supported by peers from some of the worlds most respected eye hospitals, who fly in on a specially adapted plane the flying eye hospital thanks to an initiative of Orbis, an international blindness prevention charity.

Orbis volunteers who come to share their knowledge and give technical support are very good most of them have been working for a long time so they have very good experience, says Chineshe Mboni, the paediatric ophthalmologist treating Racheal. So we have some from the US, Britain and Israel etc. Techniques are different around the world, so we get a mix of everything.

Sharing experiences and discussing cases with the visiting Orbis medical volunteers raises your confidence, to see that what you are doing is what everyone else is doing around the world, Mboni concludes.

Globally, 285 million people are blind or visually impaired and yet for 80% of them, this could be prevented with access to the right treatment like the surgery Mboni is able to give Racheal. Orbis focuses its efforts in Africa, Asia and Latin America because 90% of the worlds 39 million blind people live in developing countries. Many of the conditions causing blindness such as cataract and trachoma can be easily treated. The loss of sight these conditions can cause have a huge impact as it will impede a persons ability to gain an education, prevent them from finding employment and can plunge families into a life of poverty.

Ann-Marie Ablett, a nurse from the University Hospital of Wales in Cardiff, has been giving up four weeks of her annual leave to volunteer with Orbis since 2003. You cant change everything overnight but you can start with one patient and help them, she says. If everyone plays their small part together, you can make changes.

Ablett is speaking in a terminal at Stansted Airport and just outside is the flying eye hospital, here for a short promotional visit. The white MD-10 aircraft on the tarmac looks like a typical passenger plane. In fact, this is a 46-seat classroom complete with audio-visual equipment that transmits live surgeries that can be watched in 3D. The lead surgeon, who is just next door in a state-of-the-art operating theatre, can be asked questions throughout the procedure. The aircraft, donated by FedEx, also features pre- and post-op spaces and a laser suite.

Orbiss main aim is to train eyecare teams and strengthen hospitals in the 92 countries where it works. Its for this reason that Ablett first chose to volunteer. She says: Were not in the developing country just for numbers, were there to teach so that means we do less surgeries but when we fly off to the next country, the local doctors have got the skills to treat their own patients because they were trained up.

Dr Jonathan Lord, global medical director for Orbis, went from being a regular volunteer to giving up his position as a consultant at Moorfields eye hospital in London and becoming a staff member for the charity before being promoted to his current role.

I was just hooked after my visit trip, he says. Seeing the flying eye hospital work in real life, in the field with the patients being treated on the plane and that treatment being part of a really comprehensive training package that is upskilling all the groups of staff that are needed for each surgery, is amazing.

The need round the world is huge. You realise the magnitude when you look at some of the statistics. In Ethiopia, there is a population of over 80 million, but [until recently] there was little over 80 ophthalmologists practising in the whole country. When I left Moorfields, it had over 150 covering just the catchment area of London.

Programmes usually last two weeks, and require a lot of pre-planning with a team from Orbis flying in ahead to consult on what would be most helpful to the healthcare professionals in that country. The plane will land at a local airport and the team of local surgeons, nurses and anaesthetists board to join their volunteer counterparts. Meanwhile, another team of volunteers goes to the local hospital to provide training using the equipment in situ. At the end of the week, the teams swap.

Becoming hooked after stepping foot on the plane is a running theme among staff and volunteers, including the pilots, all FedEx employees who volunteer their time. Gary Dyson, who has been involved since 2001, says: On my first trip, which was to China, I saw a child who couldnt see on Monday but could see on Wednesday. Its such a life-changing event for them.

For Racheal, the short surgery will have undoubtedly had that effect. As Mboni removes the patches, she blinks a few times and waves her hands in front of her eyes, before looking up and seeing her mother for the first time.

News is spreading across Zambia of successes like this, Mboni says. [People] know we can act fast, so they are telling patients with eye conditions This problem? Go to Kitwe central hospital.

Laser pointer ‘attacks’ are putting boaters, pilots at risk of temporary blindness – Today’s News-Herald

Friday, May 12th, 2017

Increasing laser pointer attacks have Havasus ferry captains concerned.

The ferry between Lake Havasu City and Havasu Landing has been struck three times by green laser pointers in the past month, from locations including Windsor Beach, Crazy Horse Campground and from further within mainland Havasu. When directed into the pilots cabin, these lasers can cause temporary blindness or difficulty seeing, according to ferry Captain Greg Erkes. Laser pointers can put the crew, the ship and its passengers in jeopardy.

It can blind someone if its intense enough, Erkes said. We run our ships at night with the lights off so we can see other lights on the water. If (laser pointer owners) are doing it intentionally, then its malicious.

In Arizona, deliberately shining a laser-pointer at another person in such a way that requires medical treatment qualifies as an act of misdemeanor assault, punishable by up to one year in prison and a $2,500 fine.

Ferries arent the only recent targets of laser pointers, and the devices have proven a constant hazard for aircraft pilots as well.

Havasu-based Air Methods operates emergency medical helicopters throughout the state, and serves Havasu Regional Medical Center. While laser flashes are more common in major cities like Phoenix and Las Vegas, they are still a threat.

Pilots have been warned, dont look at them, said Air Methods spokeswoman Karey Madsen. One past crew member got hit in the eye with a lasershe was out for a while. It can cause eye damage, and it can be a distraction for the pilot. It could definitely put crews and patients in jeopardy. If a pilot cant see, they cant land or maneuver the aircraft.

Deliberately aiming a laser pointer at an aircraft is a felony in Arizona, punishable by a prison sentence up to 18 months. Federal penalties for doing so include a $250,000 fine and up to five years in prison.

New gene-delivery system can stop hereditary blindness, says study – Hindustan Times

Friday, May 12th, 2017

As per a new study, a new gene-delivery system can help deal with cases of an inherited form of blindness.

According to a new study, a new gene-delivery system for an inherited form of blindness shows promise. Researchers at Case Western Reserve University have developed gene-carrying nanoparticles that home in on target cells and prevent vision loss in mice with a human form of Leber congenital amaurosis.

The condition is one of the most common causes of blindness in children, according to the National Institutes of Health, affecting two to three of every 100,000 newborns.

Though this research focused on the form of the disease called Leber congenital amaurosis 2, or LCA2, the scientists and engineers involved in the study believe the technology holds promise for other forms of LCA as well as other inherited diseases that lead to severe vision loss or blindness.

Leader Zheng-Rong Lu said that they believe this technology can deliver almost any type of gene to tackle inherited visual disorders.

Those with LAC2 carry a mutated RPE65 gene and suffer from profound vision loss from birth. The mutated gene fails to produce RPE65 protein in the retinal pigment epithelium (RPE), a cell layer critical for protecting photoreceptors (rods and cones). The protein is an essential constituent of the visual cycle that converts light to electrical signals to the brain.

Lu and colleagues designed a lipid-based nanoparticle called ECO to deliver healthy RPE65 genes to RPE cells.

The promise of this technology is it localizes the drug to the photoreceptor cells, sparing the liver and kidney from exposure, said researcher Krzysztof Palczewski.

While other researchers focus on using modified viruses to deliver genes for therapy, sometimes the genes are too large for viruses to carry, Lu said. The ECO can be tailored to fit the cargo.

The exterior of the nanoparticle is coated with nucleic acids that act as targeting agents, drawing the delivery system to the retina and facilitating uptake by RPE cells. To track activity, Lus team included a fluorescent marker

Following injection into the retina of mice, the researchers could see fluorescent green concentrating in RPE cells. Testing showed a significant increase in light-induced electrical activity from the eyes to the brain, indicating the rods and cones were operating as they should in the visual cycle.

The therapeutic effect lasted 120 days in treated mice. No improvements were observed in untreated mice.

The researchers are now investigating whether the ECO system is effective against other visual disorders, including Stargardt disease, which is a form of inherited juvenile macular degeneration, primarily affecting the central portion of the visual field. They are also studying whether the nanoparticles can be used with the CRISPR/Cas9 gene-editing technique to treat genetic lesions related to retinal degenerative diseases.

The study appears in the journal Molecular Therapy Nucleic Acids.

Five Arunachal villages declared avoidable blindness free – The Arunachal Times

Friday, May 12th, 2017

CHANGLANG, May 11: Dapkhu, Namleng, Galenja Ponthai, Podumoni and Mohong Christian under Bordumsa were declared Avoidable Blindness Free. With the declaration, Arunachal Pradesh, and Bordumsa in particular has created a niche in the national arena in regards to Avoidable Blindness Free villages. Speaking at an event to mark the day at Bordumsa CHC on Thursday, Deputy Director General of Health Services (NPCB), New Delhi Dr Promila Gupta informed about the centres modified schemes under the national programme for Control of Blindness and committed to help the state. She later handed over certificates of avoidable blindness free to the goan burahs and Certificate of Appreciations to five ASHA workers for their tireless efforts in making their villages Avoidable Blindness Free. Global Director, Programmes, Operation Eye Sight Universal, Hyderabad Kashinath Bhoosnurmath appreciated the effort made by the NPCB team and ASHA workers in achieving the milestone. He pledged continuous support to the ongoing project and assured to come back in September with more packages for the Community Eye Care development in the state. State Programme Officer, NPCB Dr Taba Khanna outlined the road map for developing more eye-based hospitals in the state in the next two years, for which he sought liberal funding from the Government of India and help of more philanthropic non-governmental organizations. He also highlighted the challenges faced by health care workers and eye care team in Arunachal Pradesh. Franklin Daniel gave a presentation on the Avoidable Blindness Free Arunachal (ABFAR) project. He described in detail about the beginning of project implementation to declaration of avoidable blindness free. He thanked the government of Arunachal Pradesh, District Health Authority, staff of Bordumsa CHC and ASHA workers for continuous support.

Amazing technology allows the color blind to see a whole new world – WXYZ

Friday, May 12th, 2017

(WXYZ) - The videos have gone viral. People who are red-green colorblind are seen trying on glasses and then, all of a sudden, they're able to see colors they've never seen before.

Jake Gutenberg remembers being in kindergarten, looking at drawings and realizing he didn't see the same as his classmates.

"They were like 'no everything looks dull boring and dead to me'. I was like, 'it looks normal to me..I don't know what's wrong with your guys' eyes, but my eyes are perfect'," says Jake.

He's 17 years old now and about to graduate from Stevenson High School in Sterling Heights. Being red-green color blind is all he's known.

Jake says, "Everything looks similar. Some colors will stand out like blue against red, but if you put green next to it, it's hard to tell the difference between them."

He says he's adapted well since it's all he's known, but when he started seeing those online videos, he wanted to try the glasses.

"I've been wanting to try it ever since. I wanna see what everyone else sees," he says.

We were there as Jake tried the Vino Optics red-green color blindness correction glasses. After 17 years of seeing the world one way, Jake felt like the glasses changed his view. He said the glasses make everything more vivid and bright.

"You can tell the contrast. Everything doesn't look like one straight color. Everything's now spread apart and different," he says.

Dr. Nitin Kumar is an opthalmologist with Henry Ford Health Systems. He says red-green color blindness is the most common form of color blindness - with about 5 percent of the population having the genetic condition.

"People who have trouble with their reds and their greens will see the color, but they don't see the color like somebody who does not have a color vision anomaly will see them," says Dr. Kumar.

Jake really noticed a difference when he went outside.

"The leaves are green, instead of brown and almost dead looking," he says.

For Jake's parents, this has made their world brighter, too.

"It's just an amazing feeling - knowing he can see what we see and see how vibrant colors are," says Jennifer Gutenberg.

Jake's dad, WIlliam, says "His wow moment was a wow moment for us, too. It was overly exciting to see what happened. It was awesome".

There are a variety of these kinds of glasses on the market, but they don't work for every kind of color deficiency.

This is what your gritty eyes could mean – Express.co.uk

Tuesday, May 9th, 2017

GETTY

Blepharitis - also known as lid margin disease - is a potentially sight-threatening ocular condition, but only one in four British people know it exists.

Despite the fact it can lead to ulceration of the cornea and permanent damage to vision, there are many people who remain undiagnosed with the condition.

According to Moorfields Eye Hospital, one in six people in the UK displays symptoms.

Signs include crusty deposits around the lashes, gritty and painful eyes, and irritation around the eyelids.

GETTY

Burning or gritty eyes can lead to the condition, which accounts for one in 20 GP appointments for eye problems.

Abnormal eyelash growth, finding contact lenses uncomfortable to wear, and increased sensitivity to light are also indicators.

Burning or gritty eyes can lead to the condition, which accounts for one in 20 GP appointments for eye problems.

Experts believe it is being fuelled by insomnia, sugary diets, air conditioning and spending long hours at a computer screen.

However, according to a survey by eye-care specialists Bausch + Lomb, two in five people have no idea what causes it.

1 of 8

Ole Henriksen Ultimate Lift Eye Gel, 35 (0207 235 5000) Avoid if you have sensitive eyes because the gel can sting the first few times you apply it. Eyes do appear less puffy after a weeks use though. 6/10

GETTY

They also found 40 per cent of us have no idea how to manage it.

But if its not treated, or does not respond to therapy, it can lead to blindness.

While it cant be cured, you can control the symptoms and prevent permanent scarring of the eyelid margins, according to the NHS.

Francesca Marchetti, leading ocular expert and a member of the WINK advisory eye-care panel, said: Given how many people are affected by blepharitis, and the implications for vision if it is not managed effectively, these findings are extremely worrying.

GETTY

The first line treatment for blepharitis is using a combination of heat therapy, eye massage and good eyelid hygiene every day, this will manage the condition and in many cases will prevent further flare-ups.

A combination of cleansing the eyelids with special wipes and heat therapy can help.

The National Institute for Health and Care Excellence (NICE) advises: Eyelid hygiene is essential and this should be continued even when symptoms are well controlled.

They suggest applying a warm wipe to the closed eyelids for 5 to 10 minutes to loosen the debris and softens any deposits of meibum, an oily substance which protects the tear film but can problematic if the meibomian glands are blocked, or the meibum is too waxy.

Marchetti added: To have a therapeutic benefit, the heated compress must be a consistent 40 to 45C, and remain at that temperature for at least five minutes. But if it is any higher, or there are more intense hot-spots, there is a very real risk of burning or damaging the sensitive tissues around the eye.

Women face higher risk of blindness than men – Marianas Variety

Monday, May 8th, 2017

(Press Release) Studies show there is a gender gap in eye disease. Women are more likely than men to suffer from sight-threatening conditions such as age-related macular degeneration, cataracts, and glaucoma.

In support of Healthy Vision Month in May, Marianas Eye Institute and the American Academy of Ophthalmology remind women to make vision a top priority.

Women make up 65 percent of macular degeneration cases; 61 percent of glaucoma and cataract patients are women, and 66 percent of blind patients are women. Why the inequity? There are a few theories. On average women live longer and many eye problems are age-related. Some eye conditions, such as dry eye, are more common in women, young and old. Social and economic factors affect womens access to eye care, especially in developing countries.

Whatever the cause, there are a few unique vision problems women need to watch out for more than men. Dry eye occurs at double the rate in postmenopausal women. In general, women are more susceptible to autoimmune diseases than men, many of which affect vision, such as lupus, Sjogrens syndrome and hyperthyroidism. Also, pregnancy can cause vision changes due to the hormones pregnant women experience.

Good news is most vision loss is preventable. Marianas Eye Institute and the academy offers five simple steps to take control of your eye health today:

Get a comprehensive medical eye exam at age 40. Early signs of disease or changes in vision may begin at this age. An exam by one of Marianas Eye Institutes specialists is an opportunity to carefully examine the eye for diseases and conditions that may have no symptoms in the early stages.

Know your family history. Certain eye diseases can be inherited. If you have a close relative with macular degeneration, you have a 50 percent chance of developing this condition. A family history of glaucoma increases your glaucoma risk by four to nine times. Talk to family members about their eye conditions. It can help you and your eye specialist evaluate your risk.

Eat healthy foods. A diet low in fat and rich in fruits, vegetables, and whole grains, benefits the entire body, including the eyes. Eye-healthy food choices include citrus fruits, vegetable oils, nuts, whole grains, dark green leafy vegetables and cold water fish.

Stop smoking. Smoking increases the risk for eye diseases such as cataract and age-related macular degeneration. Smoking also raises the risk for cardiovascular diseases which can indirectly influence your eye health. Tobacco smoke, including second-hand smoke, also worsens dry eye.

Wear sunglasses. Exposure to ultraviolet UV light raises the risk of eye diseases, including cataract, fleshy growths on the eye and cancer. Always wear sunglasses with 100 percent UV protection and a hat while enjoying time outdoors.

Eye exams arent only about checking a persons visual acuity or sharpness, but also determining the overall health of their eyes, said Rebecca J. Taylor, M.D., clinical spokesperson for the American Academy of Ophthalmology. We encourage women as well as men to get regular eye care. By making vision a priority today, we can help protect our sight as we age.

We know that women in the CNMI drive most of their familys healthcare decisions. They are often the leaders in their families, said Russ Quinn, CEO of Marianas Eye Institute. Yet the statistics clearly show that women are at higher risk for eye disease, and we encourage them all the CNMIs women to make sure their own care receives priority, he said.

To learn more ways to keep your eyes healthy, visit the Marianas Eye Institute website.

Marianas Eye Institute is known as a regional leader in eye care, providing total eye care for the family, including express glasses, contact lenses, medical eye care, surgery and laser. Marianas Eye Institute is staffed by Dr. Dennis Williams, who has been listed in Americas Top Ophthalmologists, and Dr. Mark Robertson, a magna cum laude optometrist, along with eight other highly talented and nationally certified eye care ophthalmic technicians, opticians, and contact lens technicians. Located on Beach Road in Garapan, across 13 Fishermen Monument, Marianas Eye Institute is open Monday through Saturday and accepts new patients as well as walk-ins. Anyone interested in womens eye health can call 235-9090.

College of Optometry researchers fight myopia, blindness – The Daily Cougar

Monday, May 8th, 2017

Myopia exists when light focuses in front of the retina, rather than on top of it. | Courtesy of David Gee/College of Optometry

The University of Houstons College of Optometry is leading the charge in the fight against myopia, or nearsightedness, with several studies aimed at discovering how to fully stop the progression of the condition in children a problem that can lead to permanent blindness.

Dr. Earl Smith, Dean of the UH College of Optometry, wasnamed one of the Most Influential in Optometryin 2015 for his extensive research into myopia and was recently awarded a $1.9 million research grant by the National Eye Institute to help fund hisongoing work. Dr. David Berntsen is part of a clinical trial for childrens contact lenses that builds off of some of Smiths work, and Dr. Ruth Manny worked on two studies that tested eyeglasses and looked for myopia risk factors.

Were in the middle of an epidemic of myopia, Smith said. In Asia, East Asia, for example: Japan, Hong Kong, Taiwan, Singapore if you look at the kids graduating from technical high schools in urban areas, 80 to 95 percent are nearsighted, and theyre not a little bit nearsighted. Theyre a lot nearsighted.

Myopia exists when the eye grows too long on its axial length, Smith said, so light from a faraway object focuses in front of the retina, rather than on it. This causes objects at large distances to look blurry.

The myopia epidemic, Smith said, is likely caused by intense educational practices and lack of time outside for children. Sitting indoors, reading and studying for long hours does not give the eye enough variety in distance or exposure to sunlight. Everything inside is close to the eye, Smith said, while everything outside is far away, giving the eye the needed signal to slow growth.

Myopia is one of the largest causes of permanent blindness in Asia, he said, and the condition is taking hold in the United States. From 1970 to 2000, the number of myopia sufferers in the adult population jumped from to 45 percent from 25 percent. Those with severe myopia increased by a factor of eight, Smith said.

An estimated five billion people half of the earths population will be nearsighted by 2050 if nothing is done about the epidemic, Smith said. One billion of those five billion people will have severe myopia, Smith said, which is likely to lead to permanent blindness.

Glasses and contact lenses are the most common ways to correct nearsightedness, Smith said, because they changethe focus of the light received by the eye so that it comes to rest on the retina.

Smith said the goal of his research is to understand the role of vision in affecting eye growth. The eye has corrective systems in place so that during development, if vision is blurry, the eye will grow to correct it.

At first, Smith said, his research was focused on those suffering from lazy or crossed eyes. His focus shifted once he foundthat visual experience plays a key role in the development of those conditions and myopia.

Vision regulates the way the eye grows, whether one is nearsighted or not, Smith said. Its a fascinating thing. The eye uses visual feedback associated with defocus to regulate the way the eye grows. Because of changes in our behavior, those systems sometimes operate in ways that cause the eye to become nearsighted.

Smith said the biggest contribution his research made was proving that the periphery vision could dominate eye growth. If corrective bifocal contact lenses are applied, giving the wearer clear vision while simultaneously correcting the peripheral vision, eye growth will be slowed and myopia can be avoided, Smith said.

Dr. David Berntsen,an associate professor at the College of Optometry and fellow recipient of funding from the National Institutes of Health, is working on the Bifocal Lenses In Nearsighted Kids clinical trial.

My funding and the primary work in my lab is clinical trials in kids, looking at specific types of lenses to see if they can slow myopia progression, Berntsen said.

The funding Berntsen received is a different type of grant system that funds large-scale clinical trials, he said. The BLINK study is a collaboration between UH researchers and colleagues at Ohio State University.

BLINK enrolled about 150 kids at UH and 144 at Ohio State University, aged 7 to 11-years-old, over the course of about a year and a half, Berntsen said.

Berntsen explained that each child is randomly assigned one of three kinds of contact lenses. The control lens is one that is normally prescribed to correct myopia.The other two are bifocals with varying degrees of plus-power in the periphery of the lens focusing the light sooner at the edges, controlling eye growth according to the findings of Smiths research.The peripheral light is then focused in front of the retina, which sends a signal to the eye to slow growth.

Traditional lenses give the wearer clear central vision, but peripheral light focuses behind the retina, which may stimulate the eye to grow longer,which exacerbates myopia, Berntsen.

Corrective lenses are the standard of care for treating myopia, Berntsen said, so there are no studies comparing myopic progression with lenses versus no lenses.There are studies that have found that peripheral light focused behind the retina like with traditional spectacles is associated with faster progression than when peripheral light is focused in front of the retina,like with Berntsens bifocal contacts.

Berntsen said the ultimate goal of his research is to stop eye growth in myopic children, but currently it can only be slowed.

Another College of Optometry professor, Dr. Ruth Manny, was involved in a similar study in 2008. The Correction of Myopia Evaluation Trialaimed to understand differences in the progression of myopia in children wearing different types of eyeglasses.

The question COMET was designed to answer was: Is the increase in nearsightedness that occurs as children get older different between children who wear eyeglasses with progressive additional bifocals (no line bifocal) and children who wear conventional single vision spectacle lenses? Manny said in an email.

There were 469 children enrolled in four different cities: Houston, Boston, Philadelphia and Birmingham, Alabama. Manny said that after three years of study, researchers found that while myopia progression was less in those children wearing bifocals, the difference was too small to recommend no-line bifocals as a method to treat myopic children.

The results of COMET have led researchers to explore different treatments, Manny said, such as the bifocal contact lenses in Berntsens study.

Manny was also involved in a study called theCollaborative Longitudinal Evaluation of Ethnicity and Refractive Errorthat looked at 13 risk factors for myopia in children, and found that refractive error, orlight focusing incorrectly within the eye, was the single best predictor of the condition.

Despite working within the same college at UH, Smith, Berntsen and Manny are not directly involved in each others research, they explained.

How photography helped Gwynedd man overcome depression caused by blindness – Daily Post North Wales

Sunday, May 7th, 2017

These stunning images are remarkable - all the more so because the snapper behind them is blind.

Paul Jenkinson, 43, has Panhypopituitarism, a disease which has caused him to lose 90% if his vision in his left eye and 50% of his vision in his right eye.

He also has nystagmus, which means his eyes are constantly twitching.

Despite this, Paul, who is also colourblind and has no perception of 3D, is a keen photographer who spends most of his time taking pictures of zoo animals and beaches.

Paul, who lives in Y Ffor with his wife and two kids, said: I was diagnosed when I was 28.

At the time I was working as a buildings regulator for Gwynedd council, but I havent been able to work for 10 years due to my health issues.

I got quite depressed about everything and my photography helped pull me out of it.

Rather than sit at home twiddling my thumbs I make the most of my time taking pictures.

At times my photography can be quite limited as I have to rely on people to take me places, which is why most of my work is of animals and beaches.

Pauls Panhypopituitarism was caused by a birth defect which left him with a piece of his skull missing.

Because of the missing bone, fluid from Pauls brain has squashed his pituitary gland and his optic nerves which has caused brain haemorrhage in the past.

Along with Pauls visual issues, the condition has also caused osteoarthritis in his knees, hips and back as well as diabetes.

Paul, who was also diagnosed with prostate cancer a year and a half ago, said: It really has affected me in so many ways, but Ive not allowed my condition to hold me back.

There have been occasions when Ive taken some pictures and when I put them up on the big screen I realise theyre no good.

Because of the problems with my eyes sometimes the focus can be off or I havent been able to capture a picture the way I would have liked, but thats where Photoshop comes in!

I do like to edit pictures too, it was difficult to begin with but I got the hang of it.

I take pride in my pictures and my equipment, it really is a passion of mine.

You have to try to not let your disability ruin your life.

There is a great deal of things that limit my daily life, but I cant let it get me down, you have to get out when you can and enjoy your hobbies to the fullest.

The ideological blindness of two right-wing Israeli ministers – Haaretz – Haaretz

Sunday, May 7th, 2017

Ayelet Shaked and Yariv Levin are leading Israel to one of two bad prospects: its end as a state that is Jewish and democratic, or its official transformation into an apartheid state

Cabinet ministers Ayelet Shaked and Yariv Levin are working to impose Israeli law on the West Bank, Yedioth Ahronoth reported on Friday. They propose that every government-sponsored bill specify whether it will also apply to the territories. In practice, every new law would automatically apply to the territories, except in rare cases where the government does not want to give Palestinians the rights enjoyed by Jews. The sponsors intent is clear: to take one more step toward erasing the Green Line and annexing the West Bank its territory, not its inhabitants, in order to deprive them of any say in determining their own fate.

That is how creeping annexation works: First come the half-tracks, creeping in on their treads, then the settlers creep in, with or without the governments encouragement. The government follows, extending its official patronage to all. The law creeps in last, to lend the appearance of propriety to a situation that discriminates against the local population, is not recognized by any foreign state and whose future depends on negotiation.

Israel annexed East Jerusalem shortly after the Six-Day War, but even though in theory its residents can become naturalized citizens of Israel, in practice it is very difficult due to the obstacles Israel puts up. This is in keeping with its policy of preserving a large Jewish majority. When it annexed the Golan Heights 14 years later, de facto if not de jure technically, it only extended its administration and law to the territory that was conquered from Syria, in a disingenuous step Israel forced the areas relatively small population to accept Israeli citizenship. The state does not dare to openly violate international law by doing the same thing in the West Bank.

Three years ago, before they joined the Netanyahu government, Shaked and Levin (representing Habayit Hayehudi and Likuds right flank, respectively), together with other Knesset members, proposed a creeping annexation under the guise of imposing judicial equality on either side of the Green Line but only for Jews. That constitutes exploitation of the 50-year-old fiction that the West Bank is a military area and as such is under the rule of the commanding army officer, whose actions are dictated by military necessity. Since the Israeli military is subordinate to the cabinet, which is bound by the laws passed by the Knesset, the legislative process can be used to smuggle annexation and discrimination past the military.

Shaked and Levin are introducing their bill just weeks before U.S. President Donald Trump, who hopes to renew the peace process, is scheduled to visit Israel and the Palestinian Authority. The justice minister and tourism minister seek to preclude any chance of a possible agreement with the Palestinians, while pandering to settlers and their supporters in the headquarters and constituencies of the right-wing parties. In their ideological blindness, Shaked and Levin are leading Israel to one of two bad prospects: its end as a state that is Jewish and democratic, or its official transformation into an apartheid state.

Photojournalist once facing blindness celebrates return to 20/20 vision – CBC.ca

Sunday, May 7th, 2017

A Halifax photojournalistonce facing blindness from a rare disorder is celebrating the news that after many painful surgeries, his vision is safe.

"I got the notification [Wednesday] that all the treatments they've done have fixed everything. I'm back on track and my vision is now 20/20," Darrell Oake said from his home in Cole Harbour, N.S.

In 2011, he was diagnosed withGuillain-Barrsyndrome, a rareautoimmunedisorder that can cause weakness and paralysis. He spent a week in intensive care, barely able to move, before starting to rebuild at the Nova Scotia Rehabilitation Centre.

With the help of family and friends, Oakerelearned how to walk and got back into limited action in his work as a freelance photojournalist. But in 2014, he learned blood vessels were leaking into his eyes, causing him to "cry" when he wasn't cryinga sign the disorder was now taking his vision.

He embarked on a long course ofeye surgeries. "He did it the least invasive way he could, but it was still very painful," Oake said. "I dealt with the pain and muscled through it."

He said it's like having "new eyeballs."

"I'm still able to pick up my camera and shoot my children doing whatever they're doing, go out and enjoy nature and I can record something."

He shared some of the photos he's taken while reclaiming his vision, and they're posted throughout this article.

While most people diagnosed withGuillain-Barr syndromemake a full recovery, Oake said a pre-existing medical conditionmeanshis after-effects are lingering. He has little feeling below his knees and while he can walk, he must do so carefully. He once stepped on a carpet tack and walked with it in his foot for hours.

"I have to watch every step I take," he said. "I could trip over a pebble and break something, and if I break something, I'm doomed."

It would take more than semi-paralysis and the threat of blindness to keep Oake away from his camera. He fell in love with photography when he was 12 and his dad was stationed with the military in the U.S. Oake went into the attic and found an old camera. He was hooked.

His photographyearned him the nickname Flash in high school and many friends and colleagues would struggle to come up with his first name.

As he can't chase breaking news, he's focusing his lens on nature and his family.

"I can sit in a ditch, take a picture of one flower, and take a picture of everything around it, and be happy and content for hours."

His wifeLeanne, Oakeadmits, gets "bored out of her skull" accompanying him at times, as he needs to have someone with him when he's out.

"It says in the vows, for better or for worse, sickness and health. Well, she's gone well beyond any of those vows," he saidof his partner of 23 years.

"She nursed me back to health. If I had something I needed to have changed, she changed it. If I needed to have a feeding, she fed me. If I need somebody to lean on well, I'm leaning on her more than just my marriage vows. I'm literally leaning on her."

His teenage sons are likewise always ready to step up when their father needs something. Oake has helped himself by taking a stoic approach to his predicament.

"You can't control what happens in life. You take what life gives you. I was taken down, I got back up, and I'm going to continue on. My epitaph on my tombstone is going to read:'He wasborn, lived, loved, died.' That's all life is. I'm like a duck it just rolls off my back. I don't let it get to me.

"What's it going to do? It's going to make me miserable. I don't want to be miserable. I want to be happy."

Oake shared advice for others facing hardships. "Don't give up. I don't care if it's cancer, ifit's GBS live your life to its fullest. Don't let it take you down," he said. "If I died tomorrow, I'd die happy knowing my wife was there for me, my kids supported me and all my friends supported me.

"I got it. It's past. I'm moving forward to the future."

Irmgard Emmelhainz – E-Flux

Saturday, May 6th, 2017

Earlier this year, the Juan Rulfo Foundation withdrew from its plan to participate in the 9th annual Book and Rose Fair at the Universidad Nacional Autnoma de Mxico. The Foundation objected to Cristina Rivera Garzas scheduled presentation of her new book on Rulfo, Haba mucha neblina o humo o no s que (There was a lot of fog or smoke or I do not know), which it considered to be defamatory.

Garzas book offers Juan Rulfo as an embodiment of modernitys double bind. Known primarily for El Llano en Llamas (The Plain in Flames) a short story collection from 1953 and his novel Pedro Pramo from 1955, Rulfo worked also for Goodrich-Euzkadi, a transnational company responsible for expanding the tourism industry in Mexico. He was also an advisor and researcher for the Papaloapan Commission, the state organization charged with extracting natural resources from Southern Mexico; most notably, the commission installed the Miguel Alemn Dam in Nuevo Soyaltepec in Oaxaca. Rulfo legitimized the emblematic projects of Mexican modernity in the mid-twentieth century even as he memorialized the very peoples that his work risked erasing in his writing and photography.1 Rivera Garza compares Rulfos vision to that of Walter Benjamins Angel of History: a retrospective gaze that observeseven relishesall the details of the disaster caused by the winds pulling it toward the future.

Modernization and memorilization coincided in Rulfos position as head of publishing at the Instituto Nacional Indigenista (INI), a state institution created to look after the needs of all indigenous Mexicans. Founded in 1948 with the goal of integrating indigenous peoples into national culture by acculturating them, and thus elevating their condition, INIs policies were characterized by a homogenization of Mexicos ethnic groups. This understanding of indigenity as a problem to be solved is what links Goodrich-Euzkadi, the Papaloapan Commission, and the INI, which combined to threaten autonomous life and community work in the name of development and modernization. In the 1950s, the euphemism reacomodo, which means rearrangement or reshuffling, was coined to designate indigenous extermination while obscuring the colonial matrix.

That Rivera Garzas contradictory portrait of Rulfo would be considered defamatory is itself representative of modernitys colonial blind spot, which, like Freuds neurotic, cannot bear to hear its past openly or honestly discussed. An active agent of the Mexican states modernization project and a passionate believer in progress, Rulfos reports to the Papaloapan Commission amplified 1950s attitudes about Oaxaca as one of Mexicos backwards regions, whose natives were seen as primitive and thus nonexistent. Their territory was officially qualified as virgin (or empty). Describing the living conditions of Chinantecos and Mazatecos in the Soyaltepec Valley region, Rulfo took an active, first-hand role in their reacomodo, helping to justify the governments efforts to displace and dispossess them. Nevertheless, Rivera Garza also portrays Rulfo as an advocate working in solidarity with indigenous communities, looking melancholically at their ruin and misery though his photographs that document the imminent loss of vital, indigenous material culture.

This tension is apparent in Rulfos other works as well, such as his short story Talpa (1953) and in the script for La frmula secreta (Coca Cola en la sangre) (The secret formula: Coca-Cola in the blood, 1965), and El despojo (The plunder, 1976).2 Talpa is a confessional monologue that describes the narrators travels with his brother, Tanilo, and his wife, Natalia, to see the legendary Virgin of Talpa in the hopes that she will heal Tanilos terminal illness. The narrator describes Tanilos mutilated body in detail as it disintegrates during the pilgrimage through arid, hot, and dusty land. The trip becomes an aimless voyage toward nothing but guilt: the narrator and Tanilos wife are in love, and both know that Tanilo will not survive the trip. Yet they press him onwards, secretly desiring to finish him off forever. Tanilos death march in search of the savior Virgin becomes an allegory for indigenous reacomodo. The displacement justified by the progress of modernity and the benefits of a nation-state is in fact an aimless, self-destructive trip towards annihilation.

In a sequence from La frmula secreta, we see indigenous people in three distinct contexts: first as peasants; then in the baroque Santa Mara Tonanzintla church in San Andrs Cholula, Mexico (alluding to the hybridity of pre-Hispanic and Spanish culture in the country); and then wearing modern clothes and suspended from a ceiling. The sequence poses a question: How will originary peoples be figured or represented by the modernizing process? How will they be figured, that is, once they have Coca-Cola in the blood? What place or role will modern Mexico offer them? The film ends with a long list of transnational companies that were besieging Mexico in the 1960s. Although animated by a belief in a modern future for all, Rulfos literary and cinematic work depicts the suffering and abjection of indigenous peoples social and cultural deaths.

The double bind of modernity officially conceals the colonial carnage necessary for modern progress even as it strategically reveals this same carnage for the purpose of accruing cultural capital. The modern worlding of the world which includes the production of objective reality by experimental science, knowledge, and designcoincides with the ruthless elimination and instrumentalizaton of certain creatures by others. This blind spot is the habit of coloniality. Habit, according to Elaine Scarry, either closes down sensation entirely or builds up perception as its own interior. Habit creates sentience either by opening or closing the world.3 The habit of coloniality is ingrained in the Western unconscious, predicating universality, progress, betterment, and growth on the eradication of alterity. This is the condition of modernity itself, even as it furnishes the resources for a critique of such systemic destruction. As Rolando Vzquez argues, The narrative of salvation of modernity was built on the denial of the genocidal violence of colonialism. The first mass colonial genocide was the early expression of a system geared towards the consumption of human and nonhuman lifethat is, the consumption of the earth.4

In Mexico and Latin America, the ordeals of indigenous peoples are known as environmental conflicts. Their source is the neoliberal strategy of expropriating natural resources, or rather, the commons. This strategy has been implemented through the introduction of industrialized agriculture, a system that excludes small producers and destroys sustainability. Such extraction and exploitation of the commons is evident, for example, in mining concessions and in the construction of infrastructure projects like highways, ports, tourist enclaves, trash dumps, and dams designed to centralize energy in big cities and to connect territories rich in resources and cheap labor to the flows of global exchange. In the past fifteen years alone, the Mexican government has granted twenty-four thousand concessions for open-pit mining. Under agreements such as NAFTA, transnational corporations are entitled to file lawsuits against local governments who fail to stop local interference with their resource-extraction efforts.5 To block these neoliberal processes of capital accumulation, new forms of resistance are emerging. These seek access to and control of the means of subsistence (like land and seeds), and are accompanied by new forms of communal recomposition. Mina Lorena Navarro explains these efforts to defend territory across Latin America as a new sensibility of peoples and their environment, and as the actualization of non-predatory lifeworlds against capitalist and extractivist relationships.6

These forms of political subjectivation stand in direct opposition to capitalism. Still, they remain other, either because the habit of coloniality perceives them as non-modern, as stubborn remnants of a residual world, orin what is the opposite valence of the same judgementbecause they are romanticized and identified with the noble savage by way of this same projection of prior-ness. From the romantic point of view, indigenous struggles are regarded as a road to the future because, in fighting corporate-led environmental catastrophe, indigenous people are fighting on behalf of all of us.7 But this picture of originary peoples helping to save the future and shape new forms of worldly cohabitation is highly problematic. Part of the problem is that environmental justice struggles remain localized and culturally specific. Connections among and between them are precarious. As a result, to the extent that environmental struggles are grounded in environmental identities, environmental injustice goes hand in hand with cultural loss. Because the prevailing counterhegemonic framework amalgamates cultural identities, ways of life, and self-perception into a metaphysical connection between given communities and their physical environment, environmental struggles remain unlinked to the responsibilities that privileged inhabitants of urban areas have as the main consumers of resources such as real estate, food, and fossil fuel.8 The result is a revived pastoralism, where these same communities are used as prestige resources available for exploitation, and as a salve for colonial guilt. Perversely, the enlightened metropolitan subject uses those most victimized by the historical Enlightenment to reconfirm their commitment to those same values of freedom, justice, and equality.

However, what is at stake in indigenous peoples struggles is decidedly not freedom, equality, or justice, but rather the short-to-medium term survival of their communities and of humanity at large. This is what makes these struggles so difficult to represent outside of their own local specificities. When indigenous communities mobilize to defend their lands from narco-exploitation or from megaprojects like mining and hydroelectric plants, repression and killing are the rule. The state has beaten, tortured, imprisoned, and murdered many of those who have fought against pollution, land theft, deforestation, and the destruction of rivers.9 As I write, there is a report in the news about state police in the municipality of Nahuatzen, Michoacn murdering five people in Arantepacua. In the territories of indigenous peopleregarded by neoliberal common sense as marketsan apparatus of dispossession and a state of exception are imposed. Lorena Navarro writes that this apparatus is built on institutional consensus and legitimacy, cooptation and capture, disciplining and normalization, and criminalization and counterinsurgency. The apparatus operates on a continuum of material and representational violence that crescendos as the state becomes the guarantor of the accumulation of capital.10 The apparatus is accompanied by transnational legitimization tools like NAFTA, and US-led antidrug campaigns like Plan Colombia and Plan Mrida, which are really just forms of neocolonial war, genocide, and ethnocide.11 The habit of coloniality lurks behind the symbolic and discursive efficacy of the apparatus of dispossession.12

Detail of collective drawing by Crter Invertido as shown at the Arsenale, Venice Biennale, 2015.

Climate change is generally understood as an unintended effect of modernity. Modernity is blind to its colonial habit, and this is one reason why most environmental struggles lack a framework that connects coloniality to the Anthropocene. For instance, members of the Mexico Citybased collective Cooperativa Crter Invertido have done counter-information work in solidarity with the community of Ostula, in the state of Michoacn. The inhabitants of Ostula are currently defending their sovereignty and way of life against narcos, the military, and illegal deforestation. Symptomatically, the young artists of Cooperativa Crter Invertido have been unable to draw a link between their political activism in Ostula and political work in the city or a project of decolonization. And yet, the struggles in which the collective has engaged remain present in their fanzines, posters, and drawings. In 2015, a Communality Congress took place at a university in Puebla, gathering academics from all over Latin America to discuss the links between decolonization, environmental struggles, and new forms of community organization. Somehow, the word communality was substituted for socialism as the new politically correct ideology to which progressive researchers must now subscribe. The obvious questionhow to translate communality into urban contextswas absent from the discussion.

Another example of the blind spot inherent to the double bind of modernity is the celebratory conversation taking place around Norman Fosters Mexico City airport project. The airport is being built in Atenco, an expropriated ejido (plot of communal land) where local resistance has been taking place since president Vicente Fox announced the project in 2006. That year, resistance was followed by massive repression, including the pervasive use of gendered violence. The group Frente de Pueblos en Defensa de la Tierra (FPDT) gained international visibility for its fight against the Atenco airport, but the struggle and its repression have since been forgotten. The creative class is lobbying Foster to consult FPDT as he develops his plan for the airport, and the privileged sector of the population rejoices at how the airport will make life easier for everyone in the city. But the airport will inflict heavy human and environmental collateral damageespecially on indigenous groupsand this is conveniently forgotten in the rush to praise the project. In its neoliberal manifestation, coloniality embodies a new cycle of dispossession in Latin America, based on the belief that the lands where indigenous peoples live are more valuable than the labor their inhabitants can provide.

For Eyal Weizman, climate change has never been an unintended side effect of colonization, but rather its declared goal. In his important recent book Erasure: The Conflict Shoreline, he develops a hypothesis that connects colonialism to environmental changes. Weizmans chief case study is the battle for the Negev, in which the Israeli state has sought to uproot Bedouins from the Negev desert in order to plant forests and expand the forestation line. Weizman studies the Negevs movable frontier as it advances and recedes in response to colonization, displacement, urbanization, agricultural trends, and climate change, all phenomena intrinsically tied to dispossession. In the Negev, making the desert bloom is, in effect, changing the climate.13 In Mexico, Lake Chalco exemplifies a similar historical link between displacement and global warming. In the nineteenth century, under the regime of Porfirio Daz, Spanish entrepreneur Iigo Noriega Lasso sought to expand arable land by draining Xico, the lake adjacent to Chalco and Xochimilco on the outskirts of Mexico City. Similar to Israels displacement of the nomadic Bedouins, Noriega Lasso forced the lakes originary peoples to work as peasants in his hacienda. In the Negev, as in Chalco and Atenco, climate change and the displacement of originary populations go hand in hand.

Juan O'Gorman, Mexico City, 1949.Tempera on masonite.

In 2003, Juan Rulfos Instituto Nacional Indigenista became the Comisin Nacional para el Desarrollo de los Pueblos Indgenas (National Commission for the Development of Indigenous Peoples), or CDI, premised on the idea that indigenous groups have the right to preserve their ethnic identity and should participate in the planning of development projects. Although CDIs task is to recognize indigenous cultures and the plurality of Mexico (correcting for INIs homogenization of Mexicos ethnic groups), the organization only undermines the cultures and bodies of indigenous peoples, insofar as it reinforces their status as beings apart. In the eyes of CDI, indigenous peoples have things of their ownlike traditional customs, religious beliefs, and medical remediesthat need not only to be recorded and admired, but mined for corporate patents. Difference is relativized and continues to justify a relationship of inequality. Having been made vulnerable by neoliberal international agreements, how can indigenous peoples protect themselves, their lands, and their knowledges?14

If modernity figured indigenous peoples and their lands as the foundational (re)source of nation-states, neoliberal common sense has turned them into maquiladora laborers, sicarios, kidnappers, and illegals deported from the US. In this schema, the local bourgeoisie functions as the broker between transnational corporations and the natives as resources to be exploited. Here equality means inclusion as debtors and consumers, and those who remain outside circuits of consumption and debtthe other of homo economicusare systematically criminalized. New versions of the 1950s reacomodo have emerged in the form of efforts to displace indigenous peoples to sustainable rural cities.

From literature and philosophy to politics and the arts, discourses about Mexicos native populations are still dominated by a mentality of colonization, slavery, and dispossession. This means that indigenous populations continue to appear as other, as spectacle, as subjects of anthropology and ethnography, and more recently, as markets to be exploited.15 With the rise of neoliberal globalization, indigenous peoples have passed from being a problem that must be dealt with through modernization and civilization, to redundant populations that must be managed through repression, displacement, and genocide. They are still targeted for elimination, but less through physical death (although this is still tragically common) than through exclusion, confinement, and resource extraction. The war against underdevelopment is a war against the redundant populations of twenty-first-century capitalism.

Documentation of protests against the Highway of Deathin Texcoco-Teotihuacn, Mexico. Highway of Death is a term coined by indigenous struggles or struggles opposing megaprojects or resource extraction corporationsbecause often it literally means death to these populations. The Highway of Death connecting the City to the airport means displacement of hundreds of families and the destruction of their lands.

It is telling that in their struggles against projects of deathi.e., extraction and infrastructure projectsindigenous peoples are figured as faceless. Recall the iconic balaclava of Subcomandante Marcos, who declared: We are all behind the mask. This facelessness makes clear that the disappeared indigenous body is only visible through capitalist colonialist relationships. We must remember that while the original epoch of colonization is over, colonizing relationships persist. Government and corporate projects to transform indigenous territories into profitable markets bring indigenous groups into contact with NGOs, researchers, and development agencies that view these projects not only as emancipating oppressed communities from underdevelopment, but serving the greater good of humanity as a whole. This is why indigenous knowledges, cultures, and languages remain sites of anticapitalist strugglealbeit struggle that is culturally specific and territorially bound, and thus unable to build bridges to struggles elsewhere. For instance, the inhabitants of Chern, Michoacn dismantled state political institutions complicit with the deforestation of their territories. A new precarious politicized subject emerged, but one that was still perceived as other, non-modern, foreign, and unrepresentable. This failure of representation is closely bound up with the habit of coloniality.

A recent version of the double bind of modernity has posited design and the arts as the means to reinvent life, defend autonomous zones, and protect the environment. In this framework, cultural transformation is thought to direct new forms of political organization and bridge the gap between grassroots action and government policy. As T. J. Demos has written recently: Creative ecologies of collective resistance [can create] new combinations of images and stories, music and participation, solidarities and sacrifices [enabling] a Great Transition.16 The problem with this approach is that it remains confined to cultural representation (as opposed to political representation) and is thus prone to the fascist essentializing of culture. Moreover, as Linda Tuhiwai Smith has argued, if the Wests concept of culture remains the only legitimate form of emancipatory politicseasily universalized and not really owned by anyoneit will merely reaffirm the West as the center of all legitimate knowledge and action.17 This idea of culture will lead to a new imposition of Western authority over all aspects of indigenous struggle.

In the face of the urgent need to neutralize the extractive model, block accumulation by dispossession, and end environmental degradation and the destruction of human beings, liberals still navigate the double bind of modernity in the melancholy style of Juan Rulfo; we are just as sad, just as beautiful, just as ineffective. We must break out of this trap and realize that modernitys way of worlding the world is to annihilate worlds. A non-fascist, anticolonial form of aesthetico-political representation would encompass the counter-knowledges produced in indigenous struggles, and would ultimately lead to the dissolution of representation in favor of relation. Following Rolando Vazquez, relationality is a mode of realization that recalls and foregrounds, that sustains and gives, that is before the before. It is a coming-into-presence grounded in precedence, as opposed to representation (which always has a blind spot). Non-colonial representation acknowledges the other of modernity and colonization, and challenges the tenets of modernity itself.18 This is the aesthetic, political, and intellectual task at hand.

Field of vision: Despite blindness in left eye, West Forsyth’s Berry is … – Winston-Salem Journal

Thursday, May 4th, 2017

Brooklyn Berry has seen and done many things in her three seasons on the West Forsyth girls soccer team.

Berry, however, is limited in what she can see. The Titans talented junior forward has been blind in her left eye since eighth grade.

I tore half my retina, but the half that I tore is the half that we dont use. So I never knew it, Berry said. One day I couldnt see anything. I started losing vision, so I went to the doctor, and they told me that I had torn the half that I didnt use. And they told me it had been torn for months or years.

They told me that couldnt tell how long or what caused it because it had been so long.

Despite playing a majority of the time on the right side of the field, the lack of vision has not slowed her down.

She broke one of Alison Prices records on Tuesday and is on pace to break another. Berry broke the single-season school record of 43 goals, which was held by Price, a rising senior at Louisville, on Tuesday at Reynolds. She scored three times and now has 44 for the season.

Berry, who has verbally committed to UNC Wilmington, now has 104 career goals, 10 short of tying Prices all-time record of 114 at West Forsyth.

The cause of the injury to Berrys eye was never figured out.

Ive had so many concussions, so they told me it could really be anything, Berry said. And they told me it was just a matter of time until the rest of it (retina) fell off. So I had to get retina surgery.

The doctors inserted a new lens, but it didnt take.

I had surgery, and I had to wear an eye patch. I could only sleep on my left side. There were a bunch of things I was supposed to do. The lens shifted after, like, two days, and I went blind again, Berry said.

Some people, the lens just doesnt take. Your body just rejects it. My body just didnt take it right.

Coach Scott Bilton knew of Berrys blindness before she came to West Forsyth.

Its just been such a driving force for her, Bilton said. Shes compensated for that with the way that shell position her body so that shes able to see everything she needs to and things of that nature.

Adjusting to being able to see in just one eye has been difficult.

The first season, I had to play on the left side. Its been three or four years, so its still kind of hard, Berry said. I sometimes run into people and I dont really notice it. Ill be running and therell be somebody on my left side, and I cant really tell.

A lot of people on my team, they forget. Ive definitely gotten used to it a lot better than I used to.

Berry is not immune to injuries breaking her elbow her freshman year, pulling both hamstrings last season, and she is currently playing with a stress fracture in her foot.

In his 10th season coaching the Titans, Bilton has never seen anything like this.

Its definitely different, I guess, Bilton said. And its, obviously, something thats shocking to do what shes able to do. Shes had broken bones, just a bunch of stuff. Shes just found a way to be successful.

The Titans just clinched their seventh straight Central Piedmont 4-A conference championship and have won eight of the last 10. Before the Reynolds game, they were 18-1-1 and 10-0 with just a 4-1 loss to Cornelius Hough on April 21.

Berry has been there for the past three championships, scoring 27 goals her freshman season and 33 last season.

If the Titans make a deep run in the NCHSAA Class 4-A tournament, which starts next week, she could threaten Prices school scoring record this season. The team reached the state semifinals last season, losing 1-0 to Charlotte Providence.

The all-time state record, according to the NCHSAA, is 217 set bet Carolyn Lindsay of Hope Mills South View from 2000-03. It is possible for Berry to reach the top 15 on the list next season. Elizabeth Spencer, who played at Wilson Fike from 1996-99, has 152 goals.

The Forsyth County record set by Leigh Murray, who played at East Forsyth 1986-89, is 169 goals.

Berry said she hasnt spoken to Price about the record.

Shes a competitor, first and foremost, Bilton said of Berry. And competitors, when they set a goal, thats something that they want to go for.

Mexico eliminates infectious disease which is leading cause of … – The Yucatan Times

Thursday, May 4th, 2017

In a significant public health victory, Mexico has succeeded in eliminating a disease which is the leading cause of blindness worldwide, reportsNBC News.

The Pan American Health Organization (PAHO) and the World Health Organization (WHO) announced last weekthat Mexico is the first country in the Americas to eliminate trachoma as a public health issue. The disease, caused by a microorganism, affects the eye and repeated infections can lead to scarring and even loss of vision.

It primarily affects young children, and can be spread by personal contact or by flies that have been in contact with the discharge from the eyes or nose of an infected person.

This is a historic moment for public health in Mexico and the Americas, said Carissa F. Etienne, Director of the Pan American Health Organization (PAHO), WHO regional office for the Americas. Eliminating a disease is not achieved every day.

Trachoma primarily affects poor and isolated populations in 41 countries; in the Americas, the disease is still prevalent in Brazil, Guatemala, and Colombia.

Mexico has become the third country, after Oman and Morocco, to receive WHO validation for eliminating the disease.

In Mexico, trachoma affected over 146,000 people. The country ramped up its actions in 2004 with the creation of the Trachoma Prevention and Control Program of the Ministry of Health of Chiapas and the strengthening of the WHO SAFE strategy. The Trachoma Brigades focused on cleanliness, antibiotics, environmental improvement and surgery for the advanced stage of the disease.

The programs slogan was With water, soap and cleanliness you can prevent trachoma. Teachers at schools would also meet with parents regularly to promote better hygiene.

The international criteria for the elimination of trachoma as a public health problem includes prevalence of less than 5 percent in children aged 1 to 9, and less than one case of trachomatous trichiasis (inverted eyelashes) per 1,000 inhabitants.

Online Continuing Education Series Tackles Leading Cause of … – New England College of Optometry (press release) (blog)

Wednesday, May 3rd, 2017

Boston, MA May 2, 2017 New England College of Optometry and PlatformQ Health to host three live, online sessions in May and July, covering new insights into age-related macular degeneration and geographic atrophy. Optometrist, ophthalmologist, and retina specialists can interact with leading medical faculty and earn COPE-accredited continuing education (CE).

Age-related macular degeneration (AMD) is a chronic disease and the leading cause of irreversible blindness in the elderly of industrialized countries. The advanced form of dry AMD is geographic atrophy (GA) or atrophic AMD, a progressive, irreversible and blinding disease for which effective treatment remains a significant unmet medical need.

Optometrists play a crucial role in the ongoing eye care of patients with AMD and GA, from screening to combining imaging or functional data with a careful patient history to determining the need for subsequent care. They readily assess recognized risk factors with advanced AMD and provide disease management in the early stages, as well as prompt referral and follow up after treatment.

However, as a practical consideration for delivering eye care, the historic methodology of optometric practice may not keep pace with population aging, which leads to a corresponding increase in the prevalence of several macular diseases,and there are proportionally fewer eye care providers to care for older patients.

To help close this gap, New England College of Optometry (NECO) and PlatformQ Health are partnering to launch a free online Continuing Edseries on ClinicalSeriesLive, one of PlatformQ Healths virtual learning channels. PlatformQ Health is honored to partner with NECO on this innovative series for optometry health care professionals, says Robert Rosenbloom, CEO of PlatformQ Health. We look forward to helping bring much needed attention to the most prevalent cause of blindness inour aging population.

Clinicians can engage live with two top optometry faculty:

Age related macular degeneration is the leading cause of visual loss in older adults. Thus far, diagnosis and treatment have been limited to the wet or exudative form of this disease.New emerging insights in the dry or non-exudative form have added a significant understanding to the mechanisms of this disease, says Rishi P. Singh, MD. This online series will educate those on the front line optometrist, ophthalmologist, and retina specialists on screening, diagnosis, as well as future treatments which might be available."

This program intends to improve awareness, knowledge, and competency of optometrists about AMD and GA. The three-part series will cover screening, how to interpret results, underlying pathophysiology, the importance of referral to specialists, the crucial role of follow up, monitoring of therapeutic response in patients receiving treatment, and more. All three programs will be available on- demand following the live broadcasts.

Details on the series:

Field of vision: Despite blindness in left eye, West Forsyth’s Brooklyn … – Winston-Salem Journal

Wednesday, May 3rd, 2017

Brooklyn Berry has seen and done many things in her three seasons on the West Forsyth girls soccer team.

Berry, however, is limited in what she can see. The Titans talented junior forward has been blind in her left eye since eighth grade.

I tore half my retina, but the half that I tore is the half that we dont use. So I never knew it, Berry said. One day I couldnt see anything. I started losing vision, so I went to the doctor, and they told me that I had torn the half that I didnt use. And they told me it had been torn for months or years.

They told me that couldnt tell how long or what caused it because it had been so long.

Despite playing a majority of the time on the right side of the field, the lack of vision has not slowed her down.

She broke one of Alison Prices records on Tuesday and is on pace to break another. Berry broke the single-season school record of 43 goals, which was held by Price, a rising senior at Louisville, on Tuesday at Reynolds. She scored three times and now has 44 for the season.

Berry, who has verbally committed to UNC Wilmington, now has 104 career goals, 10 short of tying Prices all-time record of 114 at West Forsyth.

The cause of the injury to Berrys eye was never figured out.

Ive had so many concussions, so they told me it could really be anything, Berry said. And they told me it was just a matter of time until the rest of it (retina) fell off. So I had to get retina surgery.

The doctors inserted a new lens, but it didnt take.

I had surgery, and I had to wear an eye patch. I could only sleep on my left side. There were a bunch of things I was supposed to do. The lens shifted after, like, two days, and I went blind again, Berry said.

Some people, the lens just doesnt take. Your body just rejects it. My body just didnt take it right.

Coach Scott Bilton knew of Berrys blindness before she came to West Forsyth.

Its just been such a driving force for her, Bilton said. Shes compensated for that with the way that shell position her body so that shes able to see everything she needs to and things of that nature.

Adjusting to being able to see in just one eye has been difficult.

The first season, I had to play on the left side. Its been three or four years, so its still kind of hard, Berry said. I sometimes run into people and I dont really notice it. Ill be running and therell be somebody on my left side, and I cant really tell.

A lot of people on my team, they forget. Ive definitely gotten used to it a lot better than I used to.

Berry is not immune to injuries breaking her elbow her freshman year, pulling both hamstrings last season, and she is currently playing with a stress fracture in her foot.

In his 10th season coaching the Titans, Bilton has never seen anything like this.

Its definitely different, I guess, Bilton said. And its, obviously, something thats shocking to do what shes able to do. Shes had broken bones, just a bunch of stuff. Shes just found a way to be successful.

The Titans just clinched their seventh straight Central Piedmont 4-A conference championship and have won eight of the last 10. Before the Reynolds game, they were 18-1-1 and 10-0 with just a 4-1 loss to Cornelius Hough on April 21.

Berry has been there for the past three championships, scoring 27 goals her freshman season and 33 last season.

If the Titans make a deep run in the NCHSAA Class 4-A tournament, which starts next week, she could threaten Prices school scoring record this season. The team reached the state semifinals last season, losing 1-0 to Charlotte Providence.

The all-time state record, according to the NCHSAA, is 217 set bet Carolyn Lindsay of Hope Mills South View from 2000-03. It is possible for Berry to reach the top 15 on the list next season. Elizabeth Spencer, who played at Wilson Fike from 1996-99, has 152 goals.

The Forsyth County record set by Leigh Murray, who played at East Forsyth 1986-89, is 169 goals.

Berry said she hasnt spoken to Price about the record.

Shes a competitor, first and foremost, Bilton said of Berry. And competitors, when they set a goal, thats something that they want to go for.

The Next Challenge for AI: Fighting Blindness – RTInsights (press release) (blog)

Wednesday, May 3rd, 2017

May 2, 2017By Joel Hans

Researchers are using AI and other deep learning methods to create an algorithm thats capable of detecting DR with an accuracy rate of 94 percent

When we talk about artificial intelligence here at RTInsights, we typically cover topics like recommendation engines, such as selling houses on Trulia, or implementing some kind of predictive analysis to make CRM or marketing more effective.

But artificial intelligence can be used for actually improving the lives of ordinary peopleaccording to a new study conducted by researchers from the Byers Eye Institute at Stanford University, AI could soon be used to fight vision loss due to a complication that stems from diabetes.

Diabetic retinopathy(DR)affects the blood vessels at the back of the eye while a patient has diabetes, and its known to cause preventable blindness. The researchers are using AI and other deep learning methods to create an algorithm thats capable of detecting DR with an accuracy rate of 94 percent. That number applies to all the disease stagesmild to severeso its not only beneficial to those who are dealing with severe vision issues due to DR. Those in the earliest stages, when treatment can be successful at preventing vision loss, could then seek out the right specialist to mitigate any further damage.

Theodore Leng, M.D., the lead author of the report, says that this algorithm is actually quite accessibleit can be run on an ordinary personal computer, or even a smartphone, with a current average-grade processor. In order to develop the algorithm, the team used a training network of 75,000 images from patients across a range of ethnicities, to ensure the algorithm was universal. These images were then used to differentiate between a healthy patient and those with any stage of the disease.

Why use AI for the detection of DR? Diabetes affects in every 11 adults worldwide, and 45 percent of those will have some level of DR in their lifetime. Simply put, thats a lot of people, and DR is currently diagnosed by first examining the eye and then evaluating color photographs. Its a time-consuming process, even for specialists. According to Dr. Leng, doctors in areas with fewer resources are disproportionate affected, and have the most to gain from any boost in diagnostic ability.

According to Dr. Leng, fewer than half of diabetic patients are aware about how DR might be affecting them. If the algorithm could be used to detect even a portion of those patients, it could make significant inroads in helping stop preventative blindness around the world. Pilot trials will hopefully be started in the near future, followed by approval from the FDA.

Dr. Leng says, If properly implemented on a worldwide basis, this algorithm has the potential to reduce the workload on doctors and increase the efficiency of limited healthcare resources. We hope that this technology will have the greatest impact in parts of the world where ophthalmologists are in short supply.

Weve seen this trend before, with overworked radiologists who could benefit from an algorithm capable of making their work more manageable and accurate. Its not about outsourcing or replacing a doctors expertise on diagnosis, but rather giving them more tools to work from.

Researchers at Harvard Medical School have also recently been hard at work on an algorithm that can detect breast cancer with 92 percent accuracy. When paired with a trained human pathologist, the accuracy of detection rose to 99.5 percentan impressive figure that will likely save lives when rolled out widely.

Aside from analysis of diagnostic imagery, AI is being used in hospitals, along with IoT and other connectivity technology, to help seal up communication gaps and ensure that every doctor on a particular patents team is fully up-to-date on the latest progress. Even the devices used in day-to-day hospital workflows are being upgraded with networking capabilities and smart design. The AdhereTech pill bottle detects when the bottle is open, transmits information to the patients doctor, and reminds patients to take the medication. The company claims a 20 percent boost in medication adherence.

Thats a big number, but even small percentages make a big impact when it comes to peoples health. If Dr. Lengs new algorithm only improves DR detection by a single percentage point, that could still affect millions of people. And when it comes to ending preventable blindness, every correct diagnosis counts.

Political blindness is nothing new – Sun Community News

Wednesday, May 3rd, 2017

To the Editor:

About 400 years ago, in 1609, Henry Hudson explored the Hudson River.

Though long ago, his trip is still of great local interest:

The source of the Hudson is smack in the middle of the 21st Congressional District. A year later, he set about to find the Northwest Passage.

His search was sponsored by financial interests that could have benefited immensely from its discovery (think Suez Canal, Panama Canal) because it shortened the commercial trade routes between Europe and China. He didnt find it, because it didnt exist - at the time.

Observations show that ice coverage of the arctic has systematically decreased during the last half century.

Political blindness in the U.S. refuses to acknowledge this trend. At the same time, political pragmatism has prepared Russia to take advantage of this trend. Russia has a far larger fleet of icebreakers than the U.S. and has just launched the largest nuclear-powered icebreaker of all, the Arctika, on June 16, 2016.

While American politicians are debating the reality of global warming, the Russians are set to profit from it. They have opened up the long-sought Northwest Passage and are preparing to benefit from it twice over: from the trade it will enable and from the mineral resources that are now accessible under the Arctic Sea.

Our political blindness is redirecting a large source of income from the U.S. Treasury to the treasuries of other countries.

Chess ace’s comeback in the face of blindness – Wigan Today

Wednesday, May 3rd, 2017

14:46 Tuesday 02 May 2017

A determined dad has overcome his blindness to become an acclaimed chess player once again.

In fact Graham Pennington is so good that he is one of only four British people now selected to compete in the International Braille Chess Association Championships in Macedonia next month.

Former plasterer Graham started playing chess at just 12 years old after his brother Stephen taught him all the moves.

It was relatively easy to learn at this time because Graham was fully sighted and he used to play in the chess club in the Tamar pub, on Wigan Road, then began playing competitively around the age of 20.

But in 2006, when in his early 50s Graham lost his sight due to the diabetes he had been battling for years.

Facing these life-changing circumstances the father of one thought his chess-playing days were over and announced that he was giving up the game he loved so much.

But it was only after two of his good friends who recognized his skill and knew how much he loved chess encouraged him to continue playing that he took up his favourite interest again.

The now 61-year-old of Parkedge Close, has a Braille chess board where the black squares are raised and one set of pieces have raised dots on the top to help him identify them from his opponents pieces.

He has a speaking clock so he can time his moves and he uses an abacus to keep track of the number of moves made.

Graham has previously played for Lancashire and is now a member of the Atherton Chess Club and plays with sighted people here and in the Warrington League.

The Atherton Club were winners of the league this season and now Graham is getting ready for his trip to the Balkans with wife Kathleen next month.

He said: When I lost my sight I thought that was it for playing chess, but my friends persuaded me otherwise and I am so glad that they did because I love it.

I feel my way around the board and then visualise where I can next place a piece and I reckon now I am up to the standard I was before I lost my vision. Its a battle of wits more than anything else.

I do play sighted competitors and have claimed my share of scalps and I am so proud to be representing the Braille Chess Association.

There will be representatives from probably 20 other countries in Macedonia and I am so looking forward to the trip.

I am so glad that I didnt give up my main hobby and I guess it shows what you can do in the face of adversity if you put your mind to it.
