A possible cause of chronic cystic maculopathy.

An apparent increase in incidence of chronic cystic maculopathy following cataract surgery in our patients prompted an analysis of changes in surgical procedure. The important change was in the increased amount and duration of exposure to the operating lights. Previous animal research by various authors suggested to us the precipitating factor was a photic maculopathy. Various methods of avoiding excessive exposure of the patient's eye to the operating lights are discussed.
