In the United States, an estimated 11 million Americans have some form of age-related macular degeneration (AMD), which is a common eye condition and a leading cause of central vision loss among people age 60 and older. According to the National Eye Institute, approximately 2.1 million Americans have the advanced form of the disease, a leading cause of irreversible blindness and visual impairment worldwide.
The rate at which AMD advances may differ among individuals. For some, AMD advances so slowly that it takes a long time before they lose vision. In others, AMD progresses faster and may lead to a loss of vision in one or both eyes. While AMD limits central vision, it does not affect your peripheral (side) vision.
