Browse the Vision Loss Info Center website to learn more about the leading causes of vision loss. Eye diseases such as cataracts, glaucoma, macular degeneration, and diabetic retinopathy can lead to impaired vision. Early diagnosis and treatment of these conditions can slow progression of these eye diseases.

Cataracts

When the eye’s natural lens becomes sufficiently opaque to interfere with vision, it is known as a cataract. Most people over 70 suffer from cataracts. Younger people may develop cataracts as the result of excessive exposure to ultra-violet radiation.

Glaucoma

The eye continuously produces internal fluid, which is normally drained into the bloodstream through tissue known as the trabecular meshwork, located in the front of the eye. When this tissue is blocked, the excess fluid builds up pressure in the eye that can cause damage to the optic nerve. This eye disease is known as glaucoma.

Macular Degeneration

When tissue thins or deteriorates in the center of the retina, an area known as the macula, the condition is called dry macular degeneration. Wet macular degeneration occurs when abnormal blood vessels leak under the macula, causing it to become distorted. Both types of macular degeneration degrade central vision.

Diabetic Retinopathy

In people with diabetes, abnormal blood vessels may develop and rupture in the viscous material that fills the back of the eye. The leaking of blood and fluid obscures vision. This condition is known as diabetic retinopathy.
