Cystoid macular edema in pseudophakia

Abstract

Cystoid macular edema after cataract surgery, with or without intraocular lens implantation, has been reported to develop in more than 50% of patients as detected by fluorescein angiography. It is associated with reduced visual acuity in up to 8% of cases. Analysis of ongoing clinical trials at the Wilmer Institute indicates that clinically significant cystoid macular edema develops in a lower percentage of cases (2% total incidence and 0.3% persistent cystoid macular edema) if the intraocular lens implantation was uncomplicated. The factors associated with cystoid macular edema and the importance of considering clinically significant rather than just fluorescein-proven cystoid macular edema are discussed. Results of intraocular lens studies reported to the Federal Drug Administration are updated, and results of an ongoing study of prostaglandin inhibitors at the Wilmer Institute are reported.
