YAG laser treatment of cystoid macular edema.

Fourteen eyes (some aphakic and some with implanted intraocular lenses) underwent neodymium-YAG laser treatment for cystoid macular edema with vitreous incarceration in the corneoscleral wound. Visual acuity improved in all 14 eyes; ten eyes improved at least three Snellen lines and 12 eyes improved at least two Snellen lines. After follow-up periods of one to nine months, 11 eyes had visual acuities of 20/40 or better (only two had had visual acuities of 20/40 preoperatively and none had had a better visual acuity). An additional eye, which had an intraocular lens implant, was treated prophylactically. Visual acuity in this eye remained stable during a nine-month follow-up period. YAG laser treatment produced no adverse side effects or complications in any of the 15 eyes.
