What is a retinal detachment?


A retinal detachment occurs when the retina is pulled away from its normal position.  A retinal detachment is a very serious problem that almost always causes blindness unless it is treated promptly.


What causes a retinal detachment?

A clear gel called vitreous fills the middle of the eye.  As we get older, the vitreous may pull away from its attachment to the retina at the back of the eye.  Usually the vitreous separates from the retina without causing problems.  Sometimes the vitreous pulls hard enough to tear the retina in one or more places.  Fluid may pass through the retinal tear, lifting the retina off the back of the eye.
