How is macular oedema treated?



Macular oedema is treated with laser surgery. This procedure is called focal laser treatment. Your doctor places up to several hundred small laser burns in the areas of retinal leakage surrounding the macula. These burns slow the leakage of fluid and reduce the amount of fluid in the retina. The surgery is usually completed in one session. Further treatment may be needed.

A patient may need focal laser surgery more than once to control the leaking fluid. If you have macular oedema in both eyes and require laser surgery, generally only one eye will be treated at a time, usually several weeks apart.

Focal laser treatment stabilises vision. In fact, focal laser treatment reduces the risk of vision loss by 50%. In a small number of cases, if vision is lost, it can be improved. Contact your eye care professional if you have vision loss.
