Retinal Detachment


A retinal detachment is a separation of the retina from its connection at the back of the eye. The separation typically occurs with a tear or rip in the retina. The tear may be caused by separation of the vitreous humor from the retina, usually along the outside edges of the eye. The vitreous is a transparent, colorless gel that lies behind the lens and in front of the retina and fills the center of the eyeball, holding the retina in place. If the retina is weak when the vitreous pulls away, the retina will tear. Left untreated, retinal detachment can cause significant damage to the vision. Retinal detachment can also arise from either direct tugging from scar tissue (called tractional detachment) or fluid leaking from the retina vessels (exudative detachment).
