Retinal detachment caused by injury to eye

[Hina Muqadas]

The retina is the light-sensitive structure at the back of the eye. Blunt injury may cause part of the retina or the entire retina to tear or to separate (detach) from its underlying surface at the back of the eyeball.
(See also Overview of Eye Injuries.)
Usually, only part of the retina detaches (often the outside edge, or peripheral part, of the retina), but if treatment does not occur shortly after the injury, more of the retina can detach. When the retina detaches, it separates from part of its blood supply. Unless the retina is reattached soon, it may be permanently damaged by lack of blood.
