Retinal detachment is a disorder of the eye in which the retina peels away from its underlying layer of support tissue. Initial detachment may be localized or broad, but without timely treatment the entire retina may detach, leading to vision loss and blindness. It is a medical emergency, because permanent damage may occur if the detachment is not repaired within 24 �72 hours. Risk factors for retinal detachment include a family history of the condition, previous eye surgery, high myopia, and certain eye injuries. Symptoms of retinal detachment include sudden onset of floaters, flashes of light, and a loss of peripheral vision. Treatment for retinal detachment typically involves surgical repair of the retina.
