The retina is the tissue that lines the back, inner part of your eye, and the light-sensitive cells of the tissue pass along the information converted to the images you see. Some people have a retinal detachment without a known cause, but in some cases, a detachment may stem from an eye injury or disease.

Retinal detachment is a condition where the back of your retina separates from the underlying layers of the eyeball. This separation detaches the retinal tissue from the blood vessels, which then deprives the retina of blood, oxygen and other nutrients.
