The problem of mass death of birds from a wind turbine could be resolved through painting one blade black. That makes it easier for birds to avoid a deadly encounter, say the findings published in Ecology and Evolution.

The recent study found that painting one of the four white blades on a wind turbine black significantly decreases the number of dead birds by 72 per cent.

In fact, wind farms would kill twice as many bats as they do birds, the figures would be: 111 333 birds per turbine per year, and 222 666 bats per turbine/year, according to Mark Duchamp, head of Save the Eagles International.

According to the researchers from the Norwegian Institute for Nature Research conducted a trial on the remote island of Smola comparing how many birds were killed by four painted turbine compared to their untouched neighbours.

During seven and half years, the researchers regularly scoured the bottom of the turbines with specially trained sniffer dogs to identify any bird carcasses. The difference between periods when one of the four blades was painted black was impressive.

For the eight turbines included in the research four painted and four left bare a total of 1,275 searches were conducted between 2006 and 2016.

A total of 82 carcasses were found and statistical analysis revealed the birds which benefit the most from the pained blades are raptors and large soaring birds.

This includes eagles and vultures, who have been high-profile casualties of wind turbines. No white-tailed eagle carcasses were recorded after painting the blades.

The study also found that while the number of dead birds dropped at painted turbines, it did not trigger a spike in the number of casualties at neighbouring turbine zones. As the scientists suggest, the reason painting a single blade works is due to a phenomenon called motion smear.

This means that, although birds often have exceptional eyesight, the rotating blades appear invisible. Birds have extremely high-resolution eyesight in their peripheral field of vision, and the front-facing eyesight is not as good.

Thus, within assumed open airspace, birds may therefore not always perceive obstructions ahead thereby enhancing the risk of collision, the study says.

Author and Motivational Speaker, Chad Foster

Chad Fosters life took a detour when he went blind in his late teens. Now hes an executive at Red Hat, the worlds largest open source software company, an author, and a motivational keynote speaker. His memoir, Blind Ambition (published by HarperCollins Leadership), will publish in early 2021.

I had the opportunity to interview Chad recently. Here are some of the highlights of that interview:

Jill Griffin: Take us back to when you lost your sight

Chad Foster: I was studying at the University of Tennessee when my eyesight really began fading. I was diagnosed at three-years-old with retinitis pigmentosa, a genetic eye condition, and doctors told my parents Id eventually go blind.

For me, it was really just an intellectual concept, because I played sports, drove a car, and other things people take for granted. I thought maybe Id be an outlier, but my eyesight started failing in college. Going blind changed the course of my life. It was a pretty dark time, but the fire inside of me didnt flame out.

Griffin: It must have been a challenging period. What was your response?

Foster: It was dreadful. Beyond the striking emotional challenges, I was a visual learner, which wasnt useful as a blind guy. So I changed my major from pre-medicine to business. My mom read all of my business books to tape, I recorded the lectures, and I listened to the books and lectures multiple times. It turned out I was a better blind student than sighted student. I made straight A's and the Deans List, and upon graduation moved to Atlanta to work for Anderson Consulting (currently Accenture). I was terrified my support system was gone, I didn't know Atlanta, I was working in an industry requiring significant travel. Ultimately, I had to decide which fear I could live with. The fear of failing, or the fear of not knowing my potential.

Griffin: So you became more comfortable with the fear?

Foster: I learned to get comfortable with discomfort. When I was in college, my well-intended parents built a basement for me, just in case I didn't make it in the world. I started thinking of it as the loser basement, and vowed to never spend a day there. If we let others control our expectations for ourselves, whether that be our well-meaning parents or society, where will we end up? We need to live life based on our own vision of greatness.

Griffin: Andersen Consulting is a prestigious Fortune 500 company. What do you think made them seek you out?

Foster: Outstanding companies look for intelligence, drive and a willingness to try. When I explained my journey during the interview, any doubts about my determination were extinguished. In tech its easy to find a developer, but skills have a short shelf life because what will technologies look like in ten years? Whats important is finding people who are smart, naturally curious, and determined. The landscape changes so quickly that hiring for skills is less durable than hiring for traits.

Griffin: Tell me about the software you developed that Oracle said was impossible?

Foster: I taught myself to engineer my own software, and I got so good at it that people would seek me out. One day a colleague called. They had a customer with a blind employee who couldnt do his job because of a problem between their customer relationship management software and screen-reading software.-

So, I said, Yeah, I'll talk to the client, and then I started doing what I always do, which is dig for a solution.

A year or two later, I got an email asking for help with Siebel, and I responded casually saying, I've done this before.

So, we all hopped on a call me, the prospective client and their technical account manager from Oracle, the vendor of the screen-reading software, and my former client and they said, Weve talked to Oracle and the maker of the screen-reading technology and, it's not possible. And then my client said, Actually, Chad's already done it, and I've been using the technology for the last two years. Oracle started sending me clients after that.

Griffin: You were the first blind graduate of the Harvard Business Schools Program for Leadership Development. What did you learn there?

Foster: There are no black and white answers in the world of leadership. Weve got to think about and manage shades of grey. We explored the nuances of real-world business cases and observed them from many different vantage points. I learned a lot from the faculty, as well as my fellow executive classmates.

Griffin: Youre publishing your first book. Can you tell me about that?

Foster: Blind Ambition is a memoir, because the best way for people to digest the lessons Ive learned is to hear the stories from my life. Fundamentally, we all become the stories that we tell ourselves. Its about how I learned resilience by attending the school of hard knocks, being able to distinguish whats inside my sphere of influence, such as my ability to use a computer, write code, and get on stage and deliver an inspirational keynote without notes, and learning how to accept and even embrace things that are outside my sphere.

If you tell yourself youre a victim, that's how youll be. If you tell yourself I've got this, I'm owning this blindness thing, and Ill make it look good, then that's how youll be. And its a self-fulfilling prophecy, because we all become the stories playing in our minds. We can choose to move our mindset from victim to visionary.

We have to be prepared to reinvent ourselves. My blindness came in terrible wrapping paper, but its a gift that enables me to help others in a way thats not otherwise possible.

Griffin: What are some of the major themes that you touch on in your workshops?

Foster: The number one pillar is dealing with change. When going blind, I had to deal with the loss of my self-identity. I never aspired to grow up and be a blind guy, so I had to create a vision of greatness that included my blindness. All of us have faced the question what do you want to be when you grow up? No one said, I want to be a blind guy. But when life changes, we have to figure out how to visualize success. Now, I provide a framework for building resilience. Creating some space to be mindful and intentional about that allows us to respond to challenges more effectively. Coupled with strategy, effort, determination and a plan, its a winning formula.

Griffin: What inspired you to give motivational keynotes in front of thousands of people?

Foster: My tipping point was giving the graduation speech at Harvard. I had a feeling Id be elected so, being a Type-A personality, I met with a professional speaker and prepared my talk before we even voted. When I was elected, I delivered a very moving keynote. One classmate was so moved that he decided to commission an opera inspired by my story. Several others shared how Id inspired them as they faced traumatic situations. I was also moved a feeling of electricity coursed through my body, and I knew I was doing the right thing. At that point I saw how powerfully I could help others if I were to be intentional about it.

Itchiness, tiredness and sometimes burning sensation in the eyes can be a sign of eyestrain. Too much exposure to screen is one of the leading causes of eyestrain. Here are some tips you can follow to prevent this.

Exposure to screens for too long can negatively affect your eyes in several ways

When at home, you tend to spend more time staring at the screens. Too much exposure leads to several harmful effects. Eyestrain is a common condition in this digital age. Eye strain can irritate the eyes, headaches, blurry vision, dry eye, pain in neck, shoulder and back, excessive stress, poor vision and trouble in focusing. This condition can also be a result of driving for long-distance as it can make your eyes tired. But the use of digital gadgets is one of the leading causes. If left uncontrolled eye strain can lead to several problems like macular degeneration, sleep disturbances and in some cases cataract.

Eyestrain can causes discomfort in performing day to day activities too. Here are some tips you can follow to prevent this condition.

It is usually advised to take a 20 seconds break after continuous exposure to screens for 20 mins. Try to create a balance between your work and breaks so that your eyes get enough rest.

While working or watching something do not keep the screen to close to your eyes. Ideally, it is advised to keep a minimum distance of 20 inches between the screen and your eyes.

Not just the distance you should also maintain the right angle of the placement of the screen. Keep the screen at the level of your eyes or slightly below. It should not be above the eye level or too low (staring at low level can lead to text neck).

These days a variety of lenses are available. You can consult an eye specialist to get the perfect glasses for your eyes. Different lenses have different coatings and tints.

You should also describe other discomforts you are facing while working. Many experience irritation or dry eye. Your doctor may prescribe eye drops to address the issues.

When you are working, you take a break and start using your phone. In this process, you do not give your eye the required break. During a break make sure that you do not use any kind of screens.

Experiencing Eye Strain Too Often? Here Are Some Prevention Tips That Might Help - Doctor NDTV

He wasn't going to let losing his sight stop him doing the Great North Run.

So this dedicated runner certainly isn't going to let a pandemic get in the way.

The Great North Run may have been cancelled as a result of Covid-19, but Gary Ferguson, from Rowlands Gill, is among the hundreds of people who are finding a new way to test their bodies and raise money for charity, just as they planned to do in the famous half marathon.

Civil servant Gary, 59, has reached the finish line of the famous Newcastle - South Shields course around 13 times before, but this year was set to be an extra challenge.

Though he's had serious eye problems for most of his life, this was to be his first time completing the run since he eyesight deteriorate to the point where he could no longer run safely without a guide, and has applied for a guide dog.

Undeterred, Gary, who is registered blind, decided to raise cash for others in his position, running to collect sponsorship for the Guide Dogs charity, as well as the NHS.

He's now completing the Great North Run solo challenge instead: completing 40 runs over the 78 days leading up to September 13, when the half marathon should have taken place.

On the day itself, Gary and his guide runner, Craig Merrick, will be running 13.1miles along the Derwent Walk from Rowlands Gill, with Gary in a 'Braveheart' costume, an outfit he's often used in the Great North Run.

He said: "It would have been the first time I'd run it with my eyes this bad, and I was looking forward to it, because having applied for a guide dog myself I wanted to get the chance to support and raise money for them.

"It was disappointing when Covid-19 knocked it all back: it's frustrating for everybody who was going to run, but it's the charities who really suffer, because they are losing millions that they would have got in sponsorship."

Running while blind is not without its challenges, and Gary has been forced to adapt to a whole new way of doing the sport he loves, due to the cloudy cornea which makes the world around him dark and his vision 'like being in a steamy sauna'.

"It's frustrating, more than anything. Usually I like to dictate the pace, but now I have to run right behind my guide: they run right in front of me wearing a high-visibility tabard and that's about as far as I can see," he explained.

"Sometimes, depending on the weather, if the sun is shining through the trees, for example, the person I'm running behind tends to disappear, so some of the time I am literally running blind, hoping there's nothing going to hit me before that little bit of visibility comes back."

He's spurred on by his love of running outdoors, as well as a desire to help others who've lost their sight, as he knows from experience how valuable a guide dog can be.

He said: "I've been approved for a dog and I'm on a waiting list, but it's a long list because there are a lot of people needing it.

"It's about independence: at the moment I'm having to depend on other people for small things, like going to the shops, with a dog, I could do that on my own."

Bionic Eye Market Challenges and Growth Factor By 2026| Bionic Vision Australia, THE BIONIC EYE, Pixium Vision - Weekly Wall

DUBLIN--(BUSINESS WIRE)--The "Phoropters Market - Growth, Trends, and Forecast (2020-2025)" report has been added to ResearchAndMarkets.com's offering.

The global Phoropters market is anticipated to grow with a CAGR of nearly 4.1%, during the forecast period.

Certain factors that are driving the market growth include growing prevalence and recurrence of eye disorders and technological advancements.

In many developed and developing nations, eye disorders have emerged as potential threats to the status of sight of their people. The significant rise in the prevalence of diabetes in various countries has led to diabetic retinopathy being added to the priority list.

According to the WHO, in 2018, it was estimated that approximately 1.3 billion people were living with some form of vision impairment, 188.5 million people had mild vision impairment, 217 million had moderate to severe vision impairment, and 36 million people are blind.

Across the globe, the leading causes of vision impairment are uncorrected refractive errors and cataracts, and most people with vision impairment are over the age of 50 years. As per the WHO, chronic eye diseases are the number one cause of vision loss, with the top two causes being unoperated cataracts and uncorrected refractive errors. The former is the leading cause in countries with low- or middle-incomes.

In addition, the global geriatric population continues to grow at an unprecedented rate. The increase in the aging population presents several public health challenges that people need to prepare for. Presbyopia is an age-related visual impairment. It results from the gradual decrease in accommodation expected with age and can have multiple effects on quality of vision and quality of life. Though not incapacitating if corrected, presbyopia without optical correction results in an inability to perform once-effortless near tasks at a customary working distance without experiencing visual symptoms.

Hence, the rising incidence of eye-related disorders is projecting a great impact on the growth of market studied.

Key Market Trends

Specialty Clinics Hold Significant Share

Specialty clinics are expected to observe a steady growth in adoption rate of phoropters, owing to the increasing number of eye disorders. For instance, the prevalence of presbyopia is higher in societies in which larger proportions of the population survive into old age. With the aging of the U.S. population, unprecedented number of patients with presbyopia can be expected to present to optometrists' offices in the coming years.

Because presbyopia is age related, its prevalence is directly related to the proportion of older persons in the population. Although it is difficult to estimate the incidence of a chronic condition such as presbyopia, due to its slow onset, it appears that the highest incidence of presbyopia (i.e., first-reported effects) is in people aged 42 to 44 years. Hence, with the emergence of such diseases, specialty clinics are gaining attention in the market studied.

North America Dominates the Global Market

In the North American region, the United States accounted for the largest market share. According to the 2018 report of the American Optometric Association, Myopia affects nearly 30 percent of the U.S. population.

While the exact cause of myopia is unknown, there is significant evidence that many people inherit myopia, or at least the tendency to develop myopia. If one or both parents are nearsighted, there is an increased chance their children will be nearsighted.

A study conducted for the year 2016-2017 estimated that 9.6 million adults in the United States are highly myopic, or severely nearsighted. Of those, nearly 820,000 have a degenerative form of the disease and more than 41,000 suffer a complication called myopic choroidal neovascularization that could cause long-term vision loss, with women at higher risk. The findings were published in the Journal of the American Academy of Ophthalmology.

Competitive Landscape

The global Phoropters market is moderately competitive and consists of a few major players. There is a presence of local as well as international companies in the global market. Some of the key players include Briot USA Inc., Huvitz Co. Ltd., Marco, Nidek, Reichert Inc., Rexxam Co. Ltd., Carl Zeiss AG, among others.

FORT MYERS

With online learning, most kids are experiencing an increase in screen time, and that can mean tired and itchy eyes.

A local eye doctor says the blue-light-blocking glasses actually improve your eyesight by about seven percent when looking at your phone, a computer screen, or a television.

Making it more effective than simply dimming down the brightness.

You see details more clearly so you will be able to resolve letters easier so that makes you work less, so you feel less fatigued. What happens when you dim down the screen intensity, you dont see the contrast as well so you cant see details as well and the result of that is you get more fatigued from your computer, said Dr. Richard Mauer, who works at the Eye Center of Florida.

Mauer says blue light blocking treatment on eyeglass lenses can be as cheap as $30 depending on your vision plan.

Amazon sells nonprescription glasses for as little as $13.

An option that appealed to Megan Tripp, a mother of two who has concerns about long terms impacts the increased screen time could have on her children.

He has more headaches, hes grumpier, its harder for him to break away from whats in front of that screen or what is reality, Tripp said.

Megan says its also important to give your kids a break from the computer. Thats why after a couple of hours of work she takes them outside for some natural light and fresh air.

Parents worry too much screen time will have an adverse affect on children's vision - Wink News

Chrissy Suttles| csuttles@timesonline.com

AMBRIDGE Mindy Reynolds niece, Andy, will be learning remotely this fall as COVID-19 concerns remain high in her family and throughout the region.

One of her first thoughts while registering Andy for online learning was possible vision strain. Her prescription lenses are several years old, and more screen time could further hurt her eyesight.

An estimated 30,000 children in southwestern Pennsylvania lack access to proper vision care, according to the nonprofit Vision to Learn. The organization provides free eye exams and glasses to kids in high-need communities via a mobile clinic.

On Wednesday, the group stopped at Good Samaritan Catholic Church in Ambridge to give 18 youngsters in Beaver County new glasses ahead of the school year.

Shes so excited, Reynolds said. Things have been rough for a lot of families lately, so this is one easy win.

Vision to Learn has served about 280,000 kids nationwide since 2012, and about 5,000 in the Pittsburgh region since launching locally two years ago.

Wednesdays visit was their first stop in Beaver County, although the group will be partnering with Aliquippa schools this year to serve even more students; Vision to Learn partners with more than 20 school districts in the region.

Mobile clinics are equipped with self-contained optometric exam lanes with licensed optometrists. If students glasses are lost or broken, Vision to Learn replaces them for free within a year.

Its amazing to see a kid who is able to see clearly for the first time, said Vision to Learn program director Mark Scaramuzzi. For a lot of kids, they don't know they cant see. They don't know their vision is poor because its the way they've always seen. Its incredibly rewarding.

In western Pennsylvania, transportation is a significant barrier to families receiving proper care, he said, alongside low income and lack of insurance. Local staff members have traveled from New Castle to Washington, and everywhere in between, to help as many local families as possible.

We see kids on a daily basis, and sometimes its been multiple years since their glasses were broken and not replaced, Scaramuzzi said. You see kids who, in a lot of cases, have never had glasses and have very poor eyesight.

Since the start of COVID-19, staff has modified protocols to ensure social distancing. Only one child at a time can be seen at the clinic, and stations are thoroughly cleaned between each patient.

But summertime allows the group to see a greater variety of children before returning to schools in the fall.

If you cant see, you cant learn, Scaramuzzi said. And, particularly, in light of all the issues going on with COVID, were seeing more demand than ever.

Open-angle glaucoma is a disease of the eye that can slowly and painlessly cause permanent loss of vision. It rarely causes any symptoms until its in an advanced stage, which is why its known as the silent thief of sight.

Glaucoma is a leading cause of irreversible blindness in the world. If you have risk factors, being proactive and getting your eyes checked is incredibly important. Your ophthalmologist can spot the signs of early glaucoma and help stop vision loss.

So what exactly is glaucoma?

Glaucoma is a progressive disease of the optic nerve when the pressure in the eye is higher than the nerve can tolerate. Patients begin to lose their peripheral vision and over time this progresses inward. Patients with glaucoma rarely have complaints until the disease has advanced to the center of their vision; however, it is often too late to help at that point because the damage is not reversible. With early diagnosis by an eye doctor, there are many treatments available to stop glaucoma from advancing.

What can cause open-angle glaucoma?

The nerve damage in glaucoma in most cases is due to an increased pressure in the eye. Pressure levels vary for each patient and even throughout the day. Pressure is maintained by aqueous humor or fluid in the eye that is constantly produced by a tiny gland in the eye the ciliary body. This fluid flows between the iris and the lens, then out of the eye through a very small drain called the trabecular meshwork. Pressure in the eye is elevated for two main reasons: The trabecular meshwork drain is clogged and enough fluid doesnt leave the eye, or the ciliary body produces too much fluid. This elevated pressure typically does not cause any symptoms and will silently damage the nerve.

Whos at risk of developing Glaucoma?

Anyone can get glaucoma; however, some individuals are at higher risk for developing glaucoma. Those at highest risk are African American patients over the age of 50, Hispanic patients over the age of 65, patients with a family history of glaucoma and patients with diabetes. Medicare recommends to have yearly screenings for patients who fall under any of these high-risk groups in order to catch the disease at its earliest state.

How to check for glaucoma

Thanks to advances in medicine, we have the ability to diagnose glaucoma earlier and more accurately. A typical evaluation includes a comprehensive eye exam where an eye doctor analyzes the nerve for damage and measures the pressure in the eye, which should range between 8 and 21 mmHg. Additionally, there are two other tests performed to accurately diagnose if you have the disease and what stage. First, an OCT nerve scan is used to detect subtle thinning/damage of the nerve. Secondly, a visual field is performed to test for areas of missing vision.

How is glaucoma treated?

When diagnosed and treatment has begun, it is a lifelong disease that will require continuous management. We can control or slow the progression, but unfortunately cannot reverse or cure glaucoma. There are many eye drops available and, depending on the severity, more than one medication may be needed. If glaucoma cant be controlled with medications, other procedures such as laser or surgery may be considered.

For more information about glaucoma or any eye disease, call Dr. Jhaj at his office directly at 442-255-4012.

Eye Health Ingredients Market 2018 2025 What Recent Study Say About Top Companies | Trends Market Research - eRealty Express

LONDON--(BUSINESS WIRE)--Gyroscope Therapeutics Limited, a clinical-stage retinal gene therapy company, today announced the initiation of its Phase II programme evaluating its investigational gene therapy, GT005, for the treatment of geographic atrophy (GA) secondary to dry age-related macular degeneration (AMD). Dry AMD is a leading cause of permanent vision loss in people over the age of 50. GT005 is a one-time AAV-based gene therapy that is delivered under the retina. The goal of the Phase II clinical trial programme is to determine if GT005 has the potential to slow the progression of GA.

Gyroscope plans to conduct two Phase II trials evaluating GT005 in people with GA. The first, called EXPLORE, is enrolling people who have a mutation in their Complement Factor I (CFI) gene [NCT04437368]. The first patient to receive GT005 in EXPLORE was enrolled and dosed by Dr. Arshad M. Khanani at Sierra Eye Associates in Reno, Nev., USA.

Geographic atrophy is a devastating diagnosis, as there are no approved treatments for this gradual and irreversible loss of vision, said Arshad M. Khanani, M.D., M.A., Director of Clinical Research at Sierra Eye Associates and Clinical Associate Professor at the University of Nevada, Reno School of Medicine, and an investigator in the EXPLORE trial. We are excited to participate in this trial evaluating GT005 for the potential to slow progression of geographic atrophy. We believe one-time gene therapies could be a major advancement in the field of retinal disease.

GT005 is designed to restore balance to an overactive complement system, a part of the immune system, by increasing production of the CFI protein. An overactive complement system has been implicated in the development of AMD. The CFI protein regulates the activity of the complement system. It is believed that increasing CFI production will dampen the systems overactivity and reduce inflammation, with the goal of preserving a persons eyesight.

Research has found that approximately 3% of people with dry AMD have certain CFI mutations that correlate with low CFI levels in the blood and a higher risk of developing AMD.1 Gyroscope estimates that more than 100,000 people with GA in the United States and EU5 European countries may have these mutations.1,2,3,4 The EXPLORE trial will evaluate GT005 in this group of people with mutations in their CFI gene.

Research has also shown that a small supplementation of CFI can normalise complement activity in the blood,5 suggesting GT005 may also be applicable for a broader group of people with GA. It is estimated that approximately one million people in the United States alone have GA.4 Gyroscope therefore plans to initiate a second Phase II trial in 2020 that will evaluate GT005 in a broader GA population.

We are excited about the potential of GT005 for people with dry AMD. Research suggests GT005 may be best suited for people with certain mutations in their CFI gene. However, evidence also suggests it may have potential for a broader population of people with geographic atrophy, said Nadia Waheed, M.D., MPH, Chief Medical Officer of Gyroscope. We have designed our clinical programme to evaluate these groups in two distinct Phase II trials, with the goal of determining which patients GT005 may be most appropriate for and to further our understanding of the role of the complement system in AMD.

About the EXPLORE Trial

EXPLORE is a Phase II, multicentre, randomised trial evaluating the safety and efficacy of GT005 administered as a single subretinal injection.

EXPLORE is enrolling people who are aged 55 or older and have a clinical diagnosis of GA secondary to dry AMD and who have a mutation of the CFI gene. People being screened for the trial will be genotyped for the mutations. Trial participants will be randomised to one of three treatment arms: GT005 dose 1, GT005 dose 2 or a control arm. Participants in the control arm will receive current standard of care. The primary endpoint of EXPLORE is progression of GA over 48 weeks. The study will also evaluate GT005 for various safety and tolerability measures. Gyroscope plans to enroll approximately 75 patients at approximately 40 centres based in the United States, United Kingdom, Europe and Australia.

Gyroscope will announce details about the second Phase II trial of GT005 at a later date.

About Age-Related Macular Degeneration (AMD) and Geographic Atrophy (GA)

AMD is a leading cause of blindness affecting an estimated 196 million people globally.6 AMD typically affects people aged 50 and older, and causes a gradual and permanent loss of central vision that worsens over time.7 There are no approved treatments for the dry form of AMD, which is the most common, impacting approximately 90% of people with the disease.8 As dry AMD advances it leads to GA, an irreversible degeneration of retinal cells. This vision loss can be devastating, severely impacting a persons daily life as they lose the ability to drive, read and even see the faces of loved ones.

About Gyroscope Therapeutics: Vision for Life

Gyroscope Therapeutics is a clinical-stage retinal gene therapy company developing and delivering gene therapy beyond rare disease to treat a leading cause of blindness, dry AMD. Our lead investigational gene therapy, GT005, is a one-time therapy delivered under the retina. GT005 is designed to restore balance to an overactive complement system by increasing production of the Complement Factor I protein. GT005 is currently being evaluated in a Phase I/II clinical trial called FOCUS and a Phase II clinical trial called EXPLORE.

Syncona Ltd, our lead investor, helped us create the only retinal gene therapy company to combine discovery, research, drug development, a manufacturing platform and surgical delivery capabilities.

Will I go blind? Its a frightening thought that most people have when they are first told they have glaucoma.

Patients are almost always concerned that they are going to lose their vision, says Andrew Iwach, M.D., executive director of the Glaucoma Center of San Francisco. The good news for the majority of patients is that we can maintain their vision with treatment.

The sneak thief of sight

Glaucoma, an eye disease that damages the optic nerve, is the leading cause of irreversible blindness. Currently, it affects more than three million people in the United States. The National Eye Institute projects this number will rise by 58% over the next decade to 4.2 million people.

The most common form of the disease is open-angle glaucoma, which affects 90% of patients and occurs when the eyes drainage canals become clogged over time, according to the Glaucoma Research Foundation.

Open-angle glaucoma has been called the sneak thief of sight because it strikes without symptoms. In fact, experts estimate that half of the patients who have glaucoma dont know it. As much as 40% of vision can be lost without a person noticing. And once that eyesight is lost, its permanently gone.

I didnt have any symptoms prior to diagnosis, says Richie Kahn, 34, who was diagnosed in March 2019. By then, glaucoma had already stolen part of my vision. I was surprised to learn that my brain was actually compensating for my vision loss by filling in the blanks.

Hope through treatment

Since glaucoma has no symptoms in its early stages and progresses slowly over many years, eye doctors emphasize the importance of regular eye exams to detect the disease before theres a significant loss of vision.

The target for glaucoma therapy is to lower intraocular pressure (IOP). High IOP causes damage to the optic nerve, which produces vision loss in the disease. Approaches to lowering IOP include a wide range of eye drop medications, laser treatments that are performed in a doctors office, and several types of incisional surgery.

Trinh Green, M.D., has lived with glaucoma for 24 years after being diagnosed at age 21. Like Richie, she had no symptoms of the disease, so news of her diagnosis came as a total surprise. Her advice to others is to remain calm and stay optimistic throughout their care and treatment.

I think its very important for people to stay calm after learning they have glaucoma, says Trinh. There are many more treatments available in the last few years. I also owe so much to Dr. Iwach. Hes a very calming presence. Whenever there was a setback and the disease progressed, he would tell me, I have a few more tricks up my sleeve.

The power of knowledge

In addition to early detection and treatment, Dr. Iwach emphasizes the importance of patients learning everything they can about glaucoma.

Getting the facts, including risk factors and treatment options, can empower patients to improve their outcomes and reduce their fears, he says.

Dr. Iwach encourages all his patients to read Understanding and Living with Glaucoma, published by the Glaucoma Research Foundation. The free booklet, updated and newly illustrated, offers a comprehensive introduction to glaucoma and guidance about how patients can work with their doctors to manage the disease.

Glaucoma patients like Richie found power in knowledge in their fight against glaucoma.

Everyones journey will be different and you have to be willing to advocate for yourself, says Richie. I learned a lot from the Glaucoma Research Foundation. Staying informed about my particular situation allows me to be an active member of my own care team, doing my part to preserve my vision.

The clinical presentation of COVID-19 can include a variety of symptoms, but not all patients exhibit the same signs, and many infected people are asymptomatic. The novel coronavirus doesnt even have that many specific signs that would allow physicians to diagnose the infectious disease without a PCR test. The sudden loss of smell and taste is one such unique symptom thats likely to appear after a COVID-19 infection. But not for everyone.

Thats not the only downside of these unspecific COVID-19 symptoms. You might freak out whenever you experience a potential COVID-19 symptom, as youll have no way of knowing whether its the virus or something else. Only a test can bring you peace of mind, because the virus can infect various parts of the body, not just the lungs. The eye is one location where the virus can multiply, giving you a red eye or pink eye condition that you wouldnt necessarily associate with COVID-19. However, you should absolutely be aware of this possibility, as this manifestation of COVID-19 could be serious, and could even impact your eyesight.

A nurse in Kirkland, Washington said back in late March that every patient shed seen after testing positive for coronavirus had red eyes. They called the phenomenon allergy eyes because allergies can give you the same condition. Other healthcare workers noticed the same symptom in Canada in early March, detailing a case of keratoconjunctivitis in a 29-year-old patient who experienced no other major signs of COVID-19 infection. The study was published in The Canadian Journal of Ophthalmology.

The young woman spent a month in the Philippines and one day in San Francisco before returning to Canada. After one day of experiencing conjunctivitis, a clear watery discharge, and photophobia in her right eye, she went to an eye doctor. Other symptoms included rhinorrhea, cough, and nasal congestion, which we now know can be caused by COVID-19. She did not have a fever, but the medication she took over the counter may have masked it.

She returned on February 29th and went to the hospital multiple times in early March with worsening eye-related symptoms. She was diagnosed with keratoconjunctivitis, which is a complex eye condition.

As the name suggests, the diagnosis is comprised of two distinct elements. Keratitis is the inflammation of the cornea or the transparent part of the eye in front of the pupil and the iris. Conjunctivitis, meanwhile, is the inflammation of the transparent tissue that covers the white of the eye and the surface of the eyelid. In either case, you might refer to it as a red eye or pink eye the illustration above shows the anatomy of the eye.

Now, heres an image of the patients eye taken before her second visit dated March 5th:

Her eyesight was not impaired after the first two visits, but on March 5th, her vision had started to decline from 20/20 visual acuity to 20/40 pinhole to 20/30. Further examinations revealed epithelial damage and the patient continued the prescribed treatment for her condition. She did not qualify for COVID-19 testing according to the Canadian protocols at the time, but doctors had collected eye swabs to test for chlamydia, gonorrhea, and bacterial culture. The tests were negative, but the tests were later used to check for the presence of SARS-CoV-2 in the eye.

By March 6th, COVID-19 testing in Canada had changed, and she qualified for testing. A PCR test on March 8th was positive, and then samples from her eye were tested as well, confirming that the virus was present for the lesions in the eyes.

To the best of our knowledge, this is the first reported case of COVID-19 (caused by the SARS-CoV-2 virus) presenting with keratoconjunctivitis as the main symptom, the researchers concluded.

The patient did not present with conjunctivitis as previously reported for COVID-19 cases, but as keratoconjunctivitis. It was also apparent from the clinical examinations that the epithelial defects varied from one examination to the next and appeared as a pseudodendrite perhaps from a healing epithelial defect or possibly as a progressing subepithelial infiltrate.

The patients primary symptom and reason for repeatedly seeking care was a red eye with watery discharge, the study reads. If youre experiencing similar eye issues, you should consider the possibility of being infected with SARS-CoV-2. The CDC has a thorough list of coronavirus symptoms that you should check out if you suspect an infection. The New York Times created an interactive infographic that shows the most common symptoms associated with the illness.

The researches warn that healthcare workers treating patients that manifest such symptoms should know that a red eye could be an indication of COVID-19. Patients who have a red eye; respiratory symptoms such as cough and shortness of breath; and recently traveled to areas with known outbreaks are at higher risk of having COVID-19, the doctors note. Clinical interactions with any patients presenting with similar upper respiratory tract symptoms should be done with mouth and eye protection routinely if exposure to the patients secretions is possible. n this particular case, five physicians and three healthcare workers had to be placed in self-isolation for 14 days after treating the woman.

Eyesight deterioration and general eye health: what can I do to protect my vision?

It is easy to take your eyes and sight for granted, but if you develop problems, you will soon realise how much you depend on your vision every moment of every single day.

That is why it is important to look after your vision now before issues might arise that could have been avoided. The good news is that there are things you can do to lower your risk of vision loss. Lets take a look at some of them.

Investigate your familys healthy history

It is important to learn more about the health history of your family. This way, you can know if you are at a higher risk of any eye disease. For example, check if any of your family has glaucoma, high blood pressure or diabetes. If they do, you should make your eye doctor aware of this so that your eyesight can be monitored.

Regular screening for conditions like glaucoma can spot the problem early and provide you with support. Conditions like diabetes and high blood pressure can lead to eye problems if they are not addressed.

Thankfully, there is a lot of research and new treatment developments, such as at the Tej Kohli Cornea Institute, that are going to help with eye conditions.

Everyone is always telling you to enjoy a healthy diet. In particular, this is going to be important for preventing vision loss. For example, you should make sure that you enjoy a lot of fruit and vegetables in your diet. Studies are showing that leafy vegetables contain nitrates, which can lower your risk of glaucoma by up to 30 percent. This works by improving blood flow to your eyes through the nitric oxide that is created.

Making a conscious effort to adjust your meals and snacks during the day can really make a difference.

In recent years, the damage of smoking has been recognised across the world. But did you know that smoking doesn't just affect your lungs? It can also cause damage to your eyes too. For example, you can be more at risk of macular degeneration and glaucoma. It is time to kick the habit and focus on living a healthier lifestyle. While this can be difficult at first, there are many advantages to giving up smoking. Do not be afraid to reach out for support.

There are a lot of things in your daily life that can increase the risk of eye damage. You should always wear protective eyewear if you work in construction or other jobs where there are machinery and chemicals. In addition, everyone is advised to wear sunglasses in order to block out harmful UV light.

Even if you go swimming, it is recommended that you wear goggles so that chlorine does not irritate your eyes. Simple steps like these ensure your vision is protected.

How to lower your risk of vision loss - Midhurst and Petworth Observer

Your eyes deserve all the care in the world because if you get an eye disease, the world would not only be less interesting but also difficult to live in. A balanced diet and a healthy lifestyle are very important to maintain perfect vision. The deficiency of some nutrients, like vitamins A, C and E, omega-3 fatty acids, minerals like zinc, and antioxidants like lutein and zeaxanthin from your diet can lead to a number of eye diseases in the long run.

So, if you want to avoid everything from dry eyes and night blindness to cataracts and glaucomas, including foods that improve vision in your diet is very important. The best part, according to the American Academy of Ophthalmology (AAO), is that foods that are good for your eyes are also brilliant for your heart. So, include the following seven foods in your diet to improve your eye health:

1. Green leafy vegetables:Green veggies like spinach, kale, lettuce and collard arent just rich in dietary fibre and vitamin C but are also chock full of antioxidants like lutein and zeaxanthin.

2. Carrots:Vitamin A plays a vital role in maintaining vision because it is a component of a protein, rhodopsin, which helps your eyes absorb light. Carrots are also full of beta carotene, which is also essential for eye health.

3. Fish:Oily fish like tuna, salmon, mackerel, anchovies, sardines and trout are not only packed with lean proteins but also have high amounts of omega-3 fatty acids which are highly beneficial for your eyes.

4. Nuts and seeds:Vitamins, minerals, omega-3 fatty acids, antioxidants, phytochemicals - is there anything nuts and seeds have which isnt great for your eyes? Go on and include almonds, walnuts, chia seeds, sesame seeds and peanuts into your daily diet.

5. Citrus fruits:Fruits like oranges, lemons, cantaloupes, grapefruits are full of vitamin C, which is amazing for your eyes. Apart from that, these citrus fruits also pack other vitamins, essential minerals and antioxidants.

6. Eggs:There might be a lot of controversy surrounding the whole egg, but you should know that eggs are packed with healthy fats, vitamins, minerals, omega-3 fatty acids, antioxidants and proteins - and all of these are great for your eyes. So, forget what youve heard about yolks being unhealthy and eat whole eggs (in moderation, of course) for eye health.

7. Legumes:Legumes, also known as dal in India, are great sources of plant-based proteins, and also have high levels of vitamin E and omega-3 fatty acids, which are great for your vision. Make sure you have a bowl of dal every day.

Because of the impact of COVID-19, eSight had to forego a traditional launch of the product and instead move toward a virtual one.

Traditionally, we would be present at conferences where there are physical people, he said. We would also have launch events in localities like for example Florida. Its been a thing that everybody in every kind of business has had to adjust to. I think weve done quite a really good job because we were already in the process before COVID of doing demos online and working with our potential customers through the product remotely.

Don't worry that your dog's world is visually drab.Kevin Short/EyeEm via Getty Images

Do dogs really see in just black and white? Oscar V., age 9, Somerville, Massachusetts

Dogs definitely see the world differently than people do, but its a myth that their view is just black, white and grim shades of gray.

While most people see a full spectrum of colors from red to violet, dogs lack some of the light receptors in their eyes that allow human beings to see certain colors, particularly in the red and green range. But canines can still see yellow and blue.

Different wavelengths of light register as different colors in an animals visual system. Top is the human view; bottom is a dogs eye view. Top: iStock/Getty Images Plus via Getty Images. Bottom: As processed by Andrs Pter's Dog Vision Image Processing Tool

What you see as red or orange, to a dog may just be another shade of tan. To my dog, Sparky, a bright orange ball lying in the green grass may look like a tan ball in another shade of tan grass. But his bright blue ball will look similar to both of us. An online image processing tool lets you see for yourself what a particular picture looks like to your pet.

Animals cant use spoken language to describe what they see, but researchers easily trained dogs to touch a lit-up color disc with their nose to get a treat. Then they trained the dogs to touch a disc that was a different color than some others. When the well-trained dogs couldnt figure out which disc to press, the scientists knew that they couldnt see the differences in color. These experiments showed that dogs could see only yellow and blue.

In the back of our eyeballs, human beings retinas contain three types of special cone-shaped cells that are responsible for all the colors we can see. When scientists used a technique called electroretinography to measure the way dogs eyes react to light, they found that canines have fewer kinds of these cone cells. Compared to peoples three kinds, dogs only have two types of cone receptors.

Not only can dogs see fewer colors than we do, they probably dont see as clearly as we do either. Tests show that both the structure and function of the dog eye leads them to see things at a distance as more blurry. While we think of perfect vision in humans as being 20/20, typical vision in dogs is probably closer to 20/75. This means that what a person with normal vision could see from 75 feet away, a dog would need to be just 20 feet away to see as clearly. Since dogs dont read the newspaper, their visual acuity probably doesnt interfere with their way of life.

Theres likely a lot of difference in visual ability between breeds. Over the years, breeders have selected sight-hunting dogs like greyhounds to have better vision than dogs like bulldogs.

But thats not the end of the story. While people have a tough time seeing clearly in dim light, scientists believe dogs can probably see as well at dusk or dawn as they can in the bright middle of the day. This is because compared to humans, dog retinas have a higher percentage and type of another kind of visual receptor. Called rod cells because of their shape, they function better in low light than cone cells do.

Dogs also have a reflective tissue layer at the back of their eyes that helps them see in less light. This mirror-like tapetum lucidum collects and concentrates the available light to help them see when its dark. The tapetum lucidum is what gives dogs and other mammals that glowing eye reflection when caught in your headlights at night or when you try to take a flash photo.

Dogs share their type of vision with many other animals, including cats and foxes. Scientists think its important for these hunters to be able to detect the motion of their nocturnal prey, and thats why their vision evolved in this way. As many mammals developed the ability to forage and hunt in twilight or dark conditions, they gave up the ability to see the variety of colors that most birds, reptiles and primates have. People didnt evolve to be active all night, so we kept the color vision and better visual acuity.

Before you feel sorry that dogs arent able to see all the colors of the rainbow, keep in mind that some of their other senses are much more developed than yours. They can hear higher-pitched sounds from farther away, and their noses are much more powerful.

Even though Sparky might not be able to easily see that orange toy in the grass, he can certainly smell it and find it easily when he wants to.
