AIM: To explore the safety and effectiveness of 532nm laser + Nd: YAG laser in peripheral iridectomy treatment for early pupil closure glaucoma. METHODS: Fifty-six cases of pupil closure glaucoma who complied with the standards were selected and numbered randomly, and then devided into group A and B, group A(28 cases)took ND: YAG laser, group B (28 cases) took 532nm laser + ND: YAG laser treatment. The results of visual acuity, intraocular pressure (IOP), laser hole, vision and a cornerstone were observed, and the key observation was IOP control. RESULTS: After two years of clinical follow-up, IOP: (28.32 (plus or minus) 3.43) mmHg for group A before the operation, and (24.82 (plus or minus) 3.27) mmHg after the operation, using matching f-test (t (A) = 3.256, P>0.05), the results had no statistically significant differences, IOP control for group A was not ideal; (28.79 (plus or minus) 3.63)mmHg for group B before the operation, and (15.31 (plus or minus) 3.18) mmHg after the operation, using matching t-test (t(B) = 26.315, P<0.05), the results had statistically significant differences, the results of laser treatment for IOP control on group A and B, the difference was statistically significant ((chi)(2) = 42.23, P<0.05). Vision: by t-test, group A: t(A) =2.375, group B: t(B) = 2.362. Neither the vision changes for group A and B nor the difference between group A and B had statistical significance ((chi)(2) = 3.845). Complications: neither group A nor B had serious complications. CONCLUSION: 532nm laser + ND: YAG laser treatment is a safe and effective method for peripheral iridectomy on early pupil closure glaucoma, it could significantly reduce IOP, preserve the visual function.
