Age-Related Macular Degeneration

What is Age-Related Macular Degeneration?

(AMD) is a deterioration of the retina and choroid that leads to a substantial loss in visual acuity (sharpness of vision). AMD is the leading cause of significant visual acuity loss in people over age 50 in developed countries.


The exact cause of AMD is unknown, but the condition develops as the eye ages. There are 2 types of AMD: non-neovascular or dry AMD; and neovascular or wet AMD.In early stages of dry AMD, the hallmark is drusen—pale yellow lesions formed beneath the retina. 


• Distortion (warping) of straight lines
• A decrease in the intensity or brightness of colors
• A gradual or sudden loss of central vision
• Dark, blurry areas in the center of vision.
