Retinal detachment occurs when the retina is torn from its natural place. When the retina is separated, its function is disturbed and as a result the person's vision becomes blurred. That is, as if the film inside the camera is released from its place. Retinal detachment is considered a very important problem because if left untreated, it will lead to blindness in almost all cases. Almost all patients with retinal detachment need surgery to restore the retina to its normal place.
