The retina is the film in the back of the eye that light rays and images are focused on. Tiny photoreceptor cells pick up those images and transmit them to electrical impulses that are sent via the optic nerve to the brain, where visual images are interpreted.
The center of the retina is called the macula. This is the most sensitive area of the retina. It is used for reading and straight-ahead vision.
Retinal and specifically macular diseases can cause clouding and distortion of vision, loss of peripheral vision and eventually blindness.
There are many types of retinal disease. They can be devastating to the eye, and often affect your vision. At the first sign of any visual disturbance, including flashes, floaters, a curtain over your eye, or the sudden or gradual onset of blurred vision, your eye doctor should be consulted immediately.
