A: AMD is a macular disease, marked by cell death, which causes central vision deterioration. The macula is part of the retina, which is the light-sensitive tissue lining the back of the eye. Located in the center of the retina, the macula consists of photoreceptors and is responsible for processing sharp, direct vision. AMD affects the macula’s light-sensing functionality, thus disrupting the ability to distinguish objects, and perform activities, such as reading and driving.
