Supraorbital edema induced by electroconvulsive therapy.

This is a case report of an unusual side effect-unilateral supraorbital edema occurring immediately after electroconvulsive therapy ECT during each treatment occasion-in a depressed patient who was otherwise well. The affected upper eyelid appeared normal before ECT with no history of injury or abnormality. Trauma during ECT, allergic reaction to anesthetic agents, and complications of manual ventilation were found to be unlikely causes. The supraorbital edema occurred as an isolated, benign, complication of ECT and resolved spontaneously.
