Antioxidant Vitamins and Zinc Reduce Risk of Vision Loss from Age-Related Macular Degeneration
High levels of antioxidants and zinc significantly reduce the risk of advanced age-related macular degeneration (AMD) and its associated vision loss. These findings from a nationwide clinical trial are reported in the October 2001 issue of Archives of Ophthalmology.
|Vision with AMD|
People with early AMD have, in one or both eyes, either several small drusen or a few medium-sized drusen; these people do not have vision loss from AMD.
These two forms of advanced AMD can cause serious vision loss. Scientists are unsure about how or why an increase in the size and/or number of drusen can sometimes lead to advanced AMD, which affects the sharp, central vision required for the 'straight ahead' activities in our daily routine, such as reading, driving, and recognizing faces of friends.
One observation is that the larger and more numerous the drusen, the higher the risk of developing either form of advanced AMD. People who have advanced AMD in one eye are at especially high risk of developing advanced AMD in the other eye. The formulation used in the study contained several antioxidant vitamins, which are nutrients that can help maintain healthy cells and tissues. They also contained zinc, which is an important mineral incorporated into many body tissues.
