Store What is Macular Degeneration? This entire site is dedicated to information regarding Macular Degeneration, but this page will give you a quick general overview to get you oriented. Macular Degeneration Macular Degeneration is Macular degeneration leading cause of vision loss, affecting more than 10 million Americans — Macular degeneration than cataracts and glaucoma combined.

At present, Macular Degeneration is considered an incurable eye disease. Macular Degeneration is caused by the deterioration of the central portion of the retina, the inside back layer of the eye that records the images we see and sends them via the optic nerve from the eye to the brain.

Illustrations of the anatomy of a normal human eye and loss of central vision: Anatomy of a Normal Human Eye Animation of loss of central vision One can compare the human eye to a camera.

Wet And Dry Forms Of Macular Degeneration

The macula is the central and most sensitive area of the so-called film. When it is working properly, the macula collects highly detailed images at the center of the field of vision and sends them up the optic nerve to the brain, which interprets them as sight.

When the cells of the macula deteriorate, images are not received correctly. In early stages, macular degeneration does not affect vision. Later, if the disease progresses, people experience wavy or blurred vision, and, if the condition continues to worsen, central vision may be completely lost.

People with very advanced macular degeneration are considered legally blind. Even so, because the rest of the retina is still working, they retain their peripheral vision, which is not as clear as central vision.
