Brief, bright flashes of light – these flashes may be most noticeable when you move your eyes in the dark.The sudden appearance of “floaters” (dark, semi-transparent, floating shapes) in the field of vision.As more of the liquid vitreous collects behind the retina, the extent of the retinal detachment can progress and involve the entire retina, leading to a total retinal detachment. The buildup of fluid behind the retina is what separates (detaches) the retina from the back of the eye. Once the retina has torn, liquid from the vitreous gel can then pass through the tear and accumulate behind the retina. The vitreous is a clear gel that fills two-thirds of the inside of the eye and occupies the space in front of the retina. These retinal breaks may occur when the vitreous gel pulls loose or separates from its attachment to the retina, usually in the peripheral parts of the retina. Most retinal detachments are a result of a retinal break, hole or tear. Retinal detachment is a medical emergency and requires prompt treatment. ![]() When your retina becomes detached, its cells may be deprived of oxygen. This causes loss of vision that can be partial or total, depending on how much of the retina is detached. ![]() Retinal detachment occurs when the retina is separated or pulled away from its normal position in the back of the eye. The retina works with the cornea, lens and other parts of the eye and the brain to produce normal vision. The retina converts the image to signals that it sends to the brain through the optic nerve. When light passes through the eye, the lens focuses an image on the retina. The retina is a light-sensitive membrane located at the back of the eye.
