AIM:To evaluate the clinical efficacy of EX-PRESS aqueous humor drainage nail implantation combined with intravitreous injection of conbercept universal panretinal photocoagulation(PRP)in the treatment of neovascular glaucoma.

METHODS: Totally 21 patients(21 eyes)with neovascular glaucoma who met the inclusion criteria in our hospital from January 2015 to May 2018 were analyzed retrospectively. They were treated with intravitreal injection of conbercept before operation, EX-PRESS aqueous humor drainage nail was implanted after iris neovascularization disappeared 5-10d, and panretinal photocoagulation 2-3wk later. Intraocular pressure(IOP), visual acuity, recurrence rate of iris neovascularization and postoperative complications were observed after 12mo follow-up.

RESULTS: There were significant differences in intraocular pressure at different time before and after EX-PRESS aqueous drainage nail implantation(F=18.513,P<0.05). There was significant difference between preoperative and postoperative visual acuity of EX-PRESS(P=0.008). At the last follow-up, the operation was completely successful in 18 eyes(86%), the condition was successful in 2 eyes(9%), and the total success rate of operation was 95%. Recurrence of iris neovascularization occurred in 1 eye(5%), shallow anterior chamber in 1 eye(5%)and high IOP in 5 eyes(24%).

CONCLUSION: Implantation of EX-PRESS aqueous humor drainage nail combined with PRP can effectively reduce the intraocular pressure of neovascular glaucoma and can be widely used in clinical treatment.
