The retina is the layer of nerve tissue at the back of your eye, on the inner wall. It allows the light that enters your eye to be turned into an image, by sending a message along the optic nerve to your brain. When this light sensitive layer becomes separated from the inner wall of the eye it is called retinal detachment. If this happens, your vision is affected because the retina is unable to function properly. Many retinal detachments happen as a result of a tear or hole developing in the retina. This often occurs when the retina becomes thin, particularly among those who are short sighted. Retinal detachment can also be brought on by other health conditions such as diabetes, surgery for cataracts, and occasionally after a serious blow to the eye.

Procedure: If the eye surgeon thinks that retinal detachment has occurred, they will give you a full eye examination. They will have a look at your eye using an indirect ophthalmoscope, which is an instrument that allows the surgeon to see the back of your eye using a beam of light and mirrors.

 

This is done without anything actually touching your eye. Retinal holes or tears can be treated with either lasers or cryotherapy (freezing treatment). These treatments only require a local anaesthetic as they are not painful procedures. Both treatments work by making the eye create scar tissue that then seals the hole. These procedures can often prevent retinal detachment. However, if retinal detachment has occurred, the only way of reattaching the retina is with surgery. If the retina is not reattached, a complete loss of vision is almost certain.

 

Surgery for retinal detachment is usually done under a general anaesthetic, and requires a short stay in hospital (1-2 days). There are two types of surgery currently used: scleral buckling (also referred to as using encircling bands) and Vitrectomy. Scleral buckling is a procedure that involves putting pressure on the retinal detachment from the outside of the white of the eye. Fine bands of silicone rubber or sponge are stitched on, pushing in against the hole in the retina. These bands can be left on the eye, and should not be noticeable after the operation.


Vitrectomy works by removing of the vitreous (jelly-like substance) from the eye, and then replacing it with either, air, gas or silicone oil. This closes the hole in the retina from the inside. Tiny stitches are then used to close the wound, which will not need to be removed.
 

Results:
An improvement in vision should be noticeable during the weeks following the surgery however your eyesight cannot always be completely restored. This depends largely on how much of the retina was detached, and for how long.
