Age-related macular degeneration (AMD) is a degenerative eye disease that causes damage to the macula, the central part of the retina at the back of the eye that allows us to see fine details clearly. AMD can impair central vision. People who are affected by AMD may have problems reading, driving, and performing activities that require clear central vision. In severe cases, AMD makes close work like threading a needle or reading a book difficult or impossible. When the macula does not function correctly, we experience blurriness or darkness in the center of our vision. Although AMD reduces vision in the central part of the retina, it does not tend to affect peripheral vision.
