Retinal detachment describes an emergency situation in which a critical layer of tissue (the retina) at the back of the eye pulls away from the layer of blood vessels that provides it with oxygen and nourishment.
Retinal detachment leaves the retinal cells lacking oxygen. The longer retinal detachment goes untreated, the greater your risk of permanent vision loss in the affected eye.
Fortunately, retinal detachment often has symptoms that are clear warning signs. Early diagnosis and treatment of retinal detachment can save your vision. If you suspect you may have a retinal detachment, contact an eye specialist (ophthalmologist) as soon as warning signs appear.
