Retinal Detachment
The retina is to the eye what film is to the camera. This very important structure is a thin membrane in the back of the eye that contains the rod and cone cells which are responsible for light and color perception. The cells then send neurochemical messages to the brain where the information is processed into images. A serious occurrence known as retinal detachment refers to the actual physical separation, or "peeling away" of the retina from the back of the eye. This could be compared to loosening wallpaper as it separates from a wall. Retinal detachment occurs most often in older people. Retinal detachment can also follow trauma to the eye. Fluid (or blood) leaks behind the retina, causing it to separate from its much needed blood supply. Without prompt correction the retina will deteriorate and leave the patient with impaired vision.
THIS IS AN OPHTHALMOLOGICAL EMERGENCY.
The ophthalmologist will use a general or local anesthesia in an attempt to reattach the retina to its blood supply. In most cases, this type of surgery is done with a laser. If the surgery is performed early, it is successful in up to 90% of cases. Common symptoms of retinal detachment include seeing "flashing lights" or a "curtain" blocking out part of the visual field. Patients also describe seeing "spider webs" or "coal dust" drifting across the visual field. There is NO PAIN associated with retinal detachment.
