These conditions affect the shape of the eye and, in turn, how the eye sees. They can be corrected by eyeglasses, contact lenses, and in some cases surgery.

Strabismus occurs when the eyes do not line up or they are crossed. One eye, however, usually remains straight at any given time. Common forms of strabismus include:

If detected early in life, strabismus can be treated and even reversed.

If left untreated strabismus can cause amblyopia.

Amblyopia often called lazy eye is a problem that is common in children.

Amblyopia is a result of the brain and the eyes not working together. The brain ignores visual information from one eye, which causes problems with vision development.

Treatment for amblyopia works well if the condition is found early. If untreated, amblyopia causes permanent vision loss.

All people with diabetes, both type 1 and type 2, are at risk for DR. It is caused by damage to blood vessels in the back of the eye (retina). The longer someone has diabetes, the more likely he or she will get DR.

People with this condition may not notice any changes to their vision until the damage to the eyes is severe. This is why it is so important for people with diabetes to have a comprehensive eye exam every year.

There are four stages of DR. During the first three stages of DR, treatment is usually not needed. To prevent progression of diabetic retinopathy, people with diabetes should control their levels of blood sugar, blood pressure, and blood cholesterol. For the fourth stage of DR, called proliferative retinopathy, there are treatments that reduce vision loss, but are not a cure for DR.

Warning signs of diabetic retinopathy includes blurred vision, gradual vision loss, floaters, shadows or missing areas of vision, and difficulty seeing at nighttime.

People with diabetes are at greater risk for cataract and glaucoma as well.

AMD is a disease that blurs the sharp, central vision needed to see straight-ahead. It affects the part of the eye called the macula that is found in the center of the retina.The macula lets a person see fine detail and is needed for things like reading and driving.

The more common dry form of AMD can be treated in the early stages to delay vision loss and possibly prevent the disease from progressing to the advanced stage. Taking certain vitamins and minerals may reduce the risk of developing advanced AMD.

The less common wet form of AMD may respond to treatment, if diagnosed and treated early.

There are different types of glaucoma, but all of them cause vision loss by damaging the optic nerve. Glaucoma is called the sneak thief of sight because people dont usually notice a problem until some vision is lost.

The most common type of glaucoma happens because of slowly increasing fluid pressure inside the eyes.

Vision loss from glaucoma cannot be corrected. But if it is found early, vision loss can be slowed or stopped. A comprehensive eye exam is important so glaucoma can be found early.

A cataract is a clouding of the lens of the eye. It often leads to poor vision at night, especially while driving, due to glare from bright lights.

Cataracts are most common in older people, but can also occur in young adults and children.

Cataract treatment is very successful and widely available.
