Your ophthalmologist or optometrist will inspect the macula, the portion of the retina that is responsible for your central vision, as part of a comprehensive eye exam. If macular degeneration is suspected, a special photographic procedure using dye, called fluorescein angiography, may be performed. The test details the pattern of your eye's blood vessels and can detect a variety of abnormalities.
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.
