9. How is macular edema treated?

Research found that that prompt treatment of macular edema with anti-VEGF drugs, with or without laser treatment, resulted in better vision than laser treatment alone or steroid injections. When injected into the eye, these drugs reduce fluid leakage and interfere with the growth of new blood vessels in the retina.

In some cases, focal laser treatment is used along with the eye injections. Your doctor places up to several hundred small laser burns in the areas of the retina around the macula that are leaking.

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.
