The retina is a layer of nervous tissue that lines the inside of the back of the eyeball. Light stimulates the retina and messages are relayed via the optic nerve to the brain. Two retinal disorders among many are more common and will be addressed here:
Retinal Detachment service
When a hole or tear forms in the retina, fluid can get under this nerve layer and can lift if off the back of the eyeball. Retinal function of the elevated or "detached" retina is compromised which will be permanent unless the retina is reattached, usually with surgery...
Macular Degeneration & Diabetic Retinopathy service
The central part of the retina (for central, straight-ahead vision), called the macula, too often is affected in the older age groups by degenerative disease. Age-related macular degeneration (ARMD) can result in a profound loss of central vision but does not lead to total blindness, as the periphery of the retina is not involved. ..
