Although the exact causes of AMD are not fully understood, the Age-Related Eye Disease Study (AREDS
) has shown
that some antioxidant vitamins and zinc may reduce the impact of AMD in some people.
The study found that people at risk for developing advanced stages of AMD lowered their risk by
about 25% when
treated with a high-dose combination of vitamin C, vitamin E, and zinc. Among those who have either

Deposits under the retina called drusen, are a common sign of AMD. Drusen alone usually do not

but when they increase in size or numbers, this generally indicates an increased risk of developing
