We reviewed 61 consecutive eyes recently subjected to vitrectomy to determine the incidence and outcome of iatrogenic retinal tears. Iatrogenic retinal tears occurred in 14 eyes(22％). 14 eyes had 22 iatrogenic retinal tears. The incidence of iatrogenic peripheral tears was 6％ and of posterior tears was 16％. Two thirds of tears occurred in the inferior quadrants. 43％ of iatrogenic retinal tears occurred in patients with proliferative diabetic retinopathy. The overall anatomic success was achieved in 10 eyes(71％), 9 eyes of which were successfully treated with the initial operations. With a combination of intraocular gas tamponade, laser photocoagulation, cryopexy, or scleral bucking, 71％ of iatrogenic retinal tears were successfully treated.
