Amy Atcha, 47, began to suspect there was something wrong when her 72-year-old mother, Judith Arcy, wasn't able to read a menu or see the numbers on her cell phone. After a visit to the ophthalmologist, her mother's diagnosis turned out to be age-related dry macular degeneration (AMD), a chronic, degenerative eye disease that causes central vision loss.
AMD "doesn't come on all of a sudden," explains David M. Kleinman, MD, MBA, associate professor of ophthalmology at the Flaum Eye Institute, University...
To catch eye conditions early and help prevent vision loss, your doctor may recommend an eye exam every two years or more often after age 60, or if you are at high risk for an eye problem.
Here's what you should know about these threats to your eyesight.
Your Eyes and Age-Related Macular Degeneration
Age-related macular degeneration (AMD) damages, then destroys, central vision, your "straight-ahead," finely detailed vision. This eye disease takes two forms, dry and wet. About 90% of AMD cases are dry. The remaining 10% are wet, a more advanced form. Wet AMD is more damaging, causing about 90% of serious vision loss.
AMD is painless. It may worsen slowly or rapidly. Dry AMD may affect central vision within a few years. Wet AMD can cause sudden and dramatic changes in vision. In either case, early detection and treatment are key to slowing vision loss. See your eye doctor right away if you notice:
Straight lines appearing wavy, a symptom of wet AMD
Blurred central vision, the most common dry AMD symptom
Trouble seeing things in the distance
Problems seeing colors correctly
Difficulty seeing details, like faces or words on a page
Dark or "blank" spots blocking your central vision
Treatment of AMD
Wet AMD treatment may include:
Special drug injections (by far the most common treatment)
Dry AMD treatment is aimed at monitoring or slowing the progression of the disease. Vision loss from advanced dry AMD cannot be prevented. But taking certain dietary supplements may help stabilize the disease in some patients. One large study has shown that taking high doses of the antioxidantsvitamin C, vitamin E, lutein, and zeaxanthin, along with zinc may help slow AMD progression in cases of:
High risk of progressing to advanced AMD
Advanced AMD in just one eye
However, this regimen did not prevent AMD onset or slow its progression in early-stage disease.
