Macular degeneration also referred to as age-related macular degeneration (AMD or ARMD), is a disease that can blur your vision. It affects the sharp, central vision you need for activities like reading, watching TV, and driving. Because it has an impact on visual acuity, recognizing faces, using a computer, and other visual tasks that require us to see fine detail can become distorted. It is caused by changes in the macula, which is the part of the retina responsible for clear vision. As the condition becomes more advanced, the center of your field of view may appear blurry, distorted, or even dark.

About 90 percent of cases involve dry AMD. Dry AMD is a condition in which layers of the macula get progressively thinner. And the other 10 percent of cases involve wet AMD. Wet AMD is caused by abnormal blood vessels that leak fluid or blood into the macula.
