HEALTHY RETINA

The retina is nerve tissue that lines the back of the eye.  The lens of the eye helps focus the light on the retina.  The retina has special cells that interpret the light and sends signals to the brain through the optic nerve, allowing us to see.  Because the retina is made of nerve tissue, damage to the retina can cause permanent vision loss.  The retina can be affected by a number of medical conditions including diabetes, macular degeneration, and retinal tears or detachments.
