Summary
Age-related macular degeneration (AMD) is a medical condition that results in a gradual loss of vision particularly in people older than 60 years. In this condition, there are macular degenerative changes that involve the central part of the retina, resulting in impaired central vision. This can make reading, driving, and recognizing faces difficult.
