Rapid response of cystoid macular edema related to Nd:YAG laser capsulotomy to 0.5% ketorolac.

A 68-year-old woman who had had cataract surgery several years previously presented with decreasing visual acuity and posterior capsular opacification. She underwent an Nd:YAG laser capsulotomy, but developed decreased visual acuity secondary to cystoid macular edema 2 months after the procedure. She was immediately administered 0.5% ketorolac drops. Several days after initiating treatment, she noted an improvement in her vision. Eight days later, her vision had improved from 20/400 to 20/60. Three weeks later, her vision returned to her baseline of 20/30 and a fluorescein angiogram showed resolution of the edema. This may indicate that cystoid macular edema related to Nd:YAG laser capsulotomy is caused by prostaglandin release, and that it may be responsive to topical nonsteroidal drops.
