Non-steroidal anti-inflammatory agents for treating cystoid macular edema following cataract surgery.

Cataract surgery is the most common ambulatory incisional surgery performed in the USA. Cystoid macular edema (CME), the accumulation of fluid in the central retina due to leakage from dilated capillaries, is the most common cause of vision impairment following cataract surgery. Acute CME, defined as CME of less than four months' duration, often resolves spontaneously. CME that persists for four months or longer is termed chronic CME. Non-steroidal anti-inflammatory drugs (NSAIDs) have been used to treat CME. This update adds new evidence and analyses to the previously published review.
