Macular Degeneration - Dry AMD

Dry AMD

Central geographic atrophy, the “dry” form of advanced AMD, results from atrophy of the retinal pigment epithelial layer below the retina, which causes vision loss through loss of photoreceptors (rods and cones) in the central part of the eye. No medical or surgical treatment is available for this condition; however, vitamin supplements with high doses of antioxidants, lutein and zeaxanthin, have been suggested by the National Eye Institute and others to slow the progression of dry macular degeneration and, in some patients, improve visual acuity. However, recent advancements within the field of stem cell research in the United States has led to the first human embryonic stem cell trial for dry AMD, which reports positive results.

Higher beta-carotene intake was associated with an increased risk of AMD.
