Age-related macular degeneration (AMD) is the foremost cause of vision loss in the U.S., with millions of Americans showing some sign of the disorder. AMD is uncommon in people younger than 55. If you are over 65, macular degeneration may already affect your central vision -- the vision you need for driving as well as close work like reading and sewing.
AMD occurs in two forms:
Dry: Most common
Wet: Less common, but requires immediate medical attention to preserve central vision
Researchers have identified both hereditary and environmental factors. Although you can't change your genes, you can help preserve your delicate retina if you stop smoking and reduce harmful UV ray exposure from sunlight by wearing protective eyewear.
Most vision loss from ARMD is the result of leakage from abnormal blood vessels that grow underneath the retina. Prompt treatment is essential, so tell your mother to test her vision regularly with the Amsler Grid, which she can get from her eye doctor. Have her tape the grid to the bathroom mirror or the refrigerator door, and notify her eye doctor immediately if she notices any changes in how well she sees the lines on the grid.
As for supplements, certain amounts of vitamins C and E, beta carotene, zinc, and copper reduced participants' risk of developing advanced ARMD by 25%, according to the National Eye Institute's Age-Related Eye Disease Study.
