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.
Age-related macular degeneration is an eye disease with onset at any age, usually after age 60, that progressively destroys the macula, the central portion of the retina that helps with focus. It rarely causes total blindness as only the center of vision is affected. There are two types of AMD: wet and dry.
