If any part of the retina is lifted or pulled from its normal position, it is considered detached and will cause some vision loss. A detached retina is a very serious problem that almost always causes blindness unless it is treated. Usually the vitreous separates from the retina without causing a problem. But sometimes the vitreous pulls hard enough to tear the retina in one or more places. Fluid may pass through the retinal tear and lift the retina off the back of the eye like wallpaper can peel off a wall.
Retinal detachment can occur at any age, but it is more common in midlife and later.
It affects more men than women, and more Caucasians than African-Americans. This information is not a tool for self-diagnosis or a substitute for professional care.
