Dry Age-Related Macular Degeneration (AMD) is a degenerative eye condition that affects the macula, the part of the eye responsible for central vision. It is the most common cause of vision loss in people over the age of 50. Dry AMD is caused by the gradual breakdown of the macula due to aging. Symptoms of dry AMD include blurred vision, difficulty reading, and difficulty recognizing faces. Treatment for dry AMD includes lifestyle changes, such as quitting smoking, eating a healthy diet, and taking vitamins and supplements.
