RETINAL DETATCHMENT

The retina is a thin membrane made up of nerve cells that line the back 60% of your eyeball. The nerve cells in the retina detect light and send signals to the brain about what your eye sees. The retina consists of two layers that line the back portion of the eye. The sensory retina contains nerve cells that process visual information and send it to the brain. In a normal retina, the two layers lie in contact with each other. Retinal detachment occurs when the sensory retina becomes separated from the retinal pigment epithelium or RPE and the wall of the eye. Fluid from the eye flows into the space between the two layers, further separating them.

Retinal detachment most often results from posterior vitreous detachment, a harmless condition that commonly affects older adults. Injury to the eye, a blow to the head, eye disease, and conditions such as diabetes can lead to retinal detachment at any age. Tears or holes in the retina form which may lead to retinal detachment by allowing fluid from the middle of the eye to collect under the retina. Traction on the retin


Vision loss from retinal detachment can progress from minor to severe or total if the person does not seek treatment. Some detachments do not get worse, but many spread to include other parts of the retina within a few hours or days. Retinal detachment almost always demands urgent care. Retinal tears and holes, however, often do not need treatment because many of them will not lead to retinal detachment. The retina sometimes develops small, round holes as it ages. These holes are often not a problem.

Treatment for retinal detachment always involves surgery. Surgery can repair most retinal detachments and restore good vision in many cases. Treatment for retinal tears also involves surgery using lasers or other methods. Tears that occur with symptoms like floaters are more likely to lead to a retinal detachment and to require treatment. In these cases, repairing the tear can often prevent detachment and potential vision loss. The retina can be reattached about 90% of the time. How well a person sees after surgery depends on other factors. The longer a person waits f
