Ocular complications of electroconvulsive therapy.

Multiple cardioversion shocks were recently reported to cause disruption of the iris pigment epithelium. Pigment debris was deposited on the anterior lens surface, iris stroma, corneal endothelium, and trabecular meshwork. Similar findings were observed in 3 of 4 patients receiving more than 10 electroconvulsive therapy shocks and in a fifth patient who became attached to an electrified fence.
