ABSTRACT
The authors evaluated the limitation of iridocyclectomy in primate eyes. Six-clock-hour resections were tolerated and the intraocular pressure was reestablished to preoperative levels (17 mm Hg) within 1 month after surgery. Seven- to eight-clock-hour resections were also tolerated by the eyes, but the intraocular pressure remained low (7-10 mm Hg) for the extent of the study (5 months). Eyes in which the vitreous fluid was replaced with Healon showed a trend toward faster recovery of the intraocular pressure than those having a physiologic saline solution.

We have developed an intraocular laser coagulator using a low-loss single-fiber probe system connected to an argon-krypton laser. Coagulation can be accomplished at distances of 3 mm or greater from the retina, permitting easy control of lesion size, location, and intensity. The probe can be fired rapidly without overheating and can also be fired into air without damage to the tip.
