Definition of Retinal diseases
The retina is a thin layer of tissue on the inside back wall of your eye, containing millions of light-sensitive cells and other nerve cells that receive and organize visual information. Your retina sends this information to the brain through your optic nerve, enabling you to see.
Retinal diseases can affect the area of the retina that serves your central vision (the macula and the fovea at the center of the macula). Many retinal diseases share common symptoms and treatments, but each has unique characteristics. The goal of retinal disease treatments is to stop or slow disease progression and preserve, improve or restore vision.
