What is retinal detachment?
The retina is a light-sensitive membrane located at the back of the eye. When light passes through your eye, the lens focuses an image on your retina. The retina converts the image to signals that it sends to your brain through the optic nerve. The retina works with the cornea, lens, and other parts of your eye and brain to produce normal vision.
Retinal detachment occurs when the retina separates from the back of your eye. This causes loss of vision that can be partial or total, depending on how much of the retina is detached. When your retina becomes detached, its cells may be seriously deprived of oxygen. Retinal detachment is a medical emergency. Call your doctor right away if you suffer any sudden vision changes.
There’s a risk of permanent vision loss if retinal detachment is left untreated or if treatment is delayed.
