Macular degeneration, or age-related macular degeneration (AMD) is a leading cause of vision loss in Americans 60 and older. It is a disease that destroys your sharp, central vision. You need central vision to see objects clearly and to do tasks such as reading and driving. AMD affects the macula, the part of the eye that allows you to see fine detail. While AMD is not a totally blinding condition, it can be a source of significant visual disability.
