A retinal detachment occurs when the retina is separated from its normal position at the back of the eye. The retina does not work when it is detached.
People with retinal detachments often describe blurry vision or a curtain blocking part of the vision. A shower of new floaters or small flashes of light may occur as well. Usually there is no pain associated with retinal detachments.
Retinal detachments often lead to blindness if they are not repaired, so prompt evaluation by an eye doctor is important. Treatment of retinal detachments may involve a laser, gas bubble in the eye, an encircling band around the eye, and/or removal of the vitreous gel that fills the back of the eye.
