The Most Common Causes of Blindness

Glaucoma is the second most common cause of blindness in the U.S. It affects 2.7 million Americans and typically affects people who are over 40. However, infants are also at risk of developing this disease. Amblyopia is another condition that affects vision.

Amblyopia

Amblyopia is a common vision disorder that begins during childhood. Up to 3 out of 100 kids will experience some level of vision loss in their lifetimes. It can be prevented by receiving early treatment. Doctors can diagnose amblyopia using a number of screening methods, including testing for farsightedness, nearsightedness, and eye turn.

As a result, the eye looks normal, but the brain focuses more light on one eye than on the other. If the problem is left untreated, amblyopia can lead to vision problems and eventual blindness. Fortunately, treatment for amblyopia can be very effective in strengthening the vision of affected children. However, early diagnosis is critical to preventing permanent vision loss.

Glaucoma

Glaucoma is a group of eye diseases that cause damage to the optic nerve, which is crucial for good vision. This damage results in a gradual loss of vision. This condition is among the leading causes of blindness worldwide. Although the disease can develop at any age, older people are more susceptible. Many forms of glaucoma cause no visible symptoms in the early stages. As a result, early diagnosis and treatment is important.

A family history of glaucoma increases the risk of developing this eye disease. The risk of developing glaucoma also increases with age. People of African descent and Hispanics are more likely to develop this eye disease than Caucasians. People with certain medical conditions may also be at risk for glaucoma, such as high nearsightedness or high blood pressure.

Diabetic Retinopathy

The damage to the retina is irreversible and can cause blindness. It is one of the leading causes of blindness among adults in the U.S.

Treatment for diabetic retinopathy can include laser surgery to shrink abnormal blood vessels, or laser treatment to seal leaking vessels. Injections are also used to slow down the growth of abnormal blood vessels in the retina. These treatments are effective in preventing or reversing vision loss caused by diabetic retinopathy.

Cataracts

Cataracts are caused by the clouding of the eye's natural lens, which is responsible for focusing light in the eye. Normally, this lens is transparent, which allows light to enter the eye and focus on the retina for clear vision. As we age, our lenses gradually lose their flexibility, becoming thicker and cloudier. This causes light to scatter instead of reaching the retina, which is responsible for seeing sharp images.

The symptoms of cataracts are often asymptomatic and can even be mistaken for other eye problems. However, it's important to see a doctor if you notice any of these symptoms. Cataracts often affect a person's near-and-far vision, making it difficult to read, drive, or do other activities that require clear vision. This condition can also result in frequent eyeglass prescription changes
