Peripheral iridoplasty with doubled-frequency Nd:YAG laser as treatment for angle-closure glaucoma / 浙江大学学报·医学版

ABSTRACT

OBJECTIVE: To examine the effects and safety of doubled-frequency NdYAG laser peripheral iridoplasty(LPI) for angle-closure glaucoma (ACG) with relieving the pupillary block. METHODS: Thirty-seven eyes of 29 patients of ACG with mean intraocular pressure (IOP) of (33.5+/-9.3)mmHg, were treated by LPI. In the follow-up of 5 approximate, equals 35 months, the IOP, angle and complications from LPI were examined. RESULTS: The mean IOP of the patients was reduced to (17.2+/-5.3)mmHg (P<0.0001). Thirty-three eyes of 25 patients, who had negative of dark room provocative test, maintained the angle opened without adjunctive antiglaucoma treatment. Four eyes of 4 patients continued to developed angle closure and had a high IOP. CONCLUSION: Peripheral iridoplasty doubled frequency NdYAG laser is a safe and effective method for treatment of ACG.
