Macular degeneration (AMD) is caused by deterioration of the central portion of the retina. This central portion, the macula, is the part of the eye with the highest visual sharpness. It greatly influences our ability to read, drive a car, recognize faces and colors, and see objects in fine detail.
In its early stages, macular degeneration does not significantly affect vision. As the disease progresses, objects may appear distorted. wavy, or blurry. In more advanced stages, central vision may be significantly impaired, or even lost.
