Abstract

To evaluate the efficacy and immediate complications of Q-switched Nd:YAG laser iridotomy in the treatment of angle closure glaucoma, Q-switched Nd:YAG laser iridotomy using coherent model 7900(U.S.A.)was performed on 50 eyes, 43 patients with angle closure glaucoma between Feb. 1987 and Mar. 1988. Forty-six eyes of Thirty-nine Patients had been followed up {or more than 2 months. Four eyes were lost to follow-up. Among 50 treated eyes, 46 required a single laser session for patency and four eyes required two sessions. Intraocular pressure was significantly decreased after Q-switched Nd: YAG laser iridotomy and the continuous use of previous glaucoma medications as necessary(p<0.01). Immediate postoperative intraocular pressure elevation was seen in two Nd:YAG-treated eyes. Thirty-five eyes treated with the Nd:YAG laser had minimal bleeding from the iridotomy site. Forty-four Nd:YAG-treated eyes had transient iritis.
