Thirteen years after cataract extraction, a patient complained of diminished visual acuity. In the interim visual acuity was 6/6 (20/20), or 6/7.5 (20/25+2). Fluorescein angiography demonstrated cystoid macular edema. Except for vitreous adherence to the inner surface of the cataract wound, no ocular cause for the macular edema was apparent.
