Cystoid macular edema following photorefractive keratectomy complicated by presumptive infectious keratitis.

A 71-year-old man developed cystoid macular edema (CME) following photorefractive keratectomy (PRK). He had a history of CME following cataract surgery in both eyes, which had responded well to topical steroid and nonsteroidal antiinflammatory drops. The cataract surgery in the left eye had resulted in a hyperopic surprise, with secondary anisometropia and visual discomfort. For this reason, the patient elected to have PRK. Three weeks after the procedure, he returned, complaining of visual loss. Optical coherence tomography and fluorescein angiography confirmed the presence of CME. This responded well to topical and sub-Tenon's corticosteroids and nonsteroidal antiinflammatory drops.
