Milton Flocks, MD, and H. Christian Zweng, MD, of the Division of Ophthalmology, Stanford University School of Medicine, reported results of photocoagulation in 25 patients, 23 of whom were treated with retinal photocoagulation and two with surface photocoagulation to the iris. Most of the cases treated were for peripheral retinal tear.

All but one patient (a retinal detachment case) were treated as outpatients and were allowed to resume essentially normal postoperative activities not involving heavy physical exertion.
