Age-related macular degeneration, often called AMD, usually affects older adults and results in a loss of vision in the center of the visual field (the macula) because of damage to the retina. It occurs in âdryâ and âwetâ forms, and is a major cause of blindness and visual impairment in adults over 50 years of age.
There is currently no treatment available to reverse dry macular degeneration. However, dry macular degeneration is usually slowly progressive and most patients with this condition are able to live relatively normal, productive lives. Often one eye is affected more than the other. Once dry AMD reaches the advanced stage, no form of treatment can prevent further vision loss.
