AIM: To evaluate the effect and safety of conbercept combined with trabeculectomy and retinal photocoagulation in the treatment of nevoascular glaucoma.

METHODS: A retrospectively analysis study. The clinical data of 47 patients(47 eyes)with neovascular glaucoma admitted to Shaanxi Eye hospital from January 2018 to December 2020. The patients were followed up for 6mo to observe the changes of visual acuity and intraocular pressure and the occurrence of complications before and after treatment.

RESULTS: At 6mo after compound trabeculectomy, the visual acuity of this group of patients improved in 25 eyes(53%), among which 8 eyes without light perception before operation, visual acuity increased to 0.2 and 0.02 respectively, to hand motion/30cm in 2 eyes,restoring light perception from no light perception 2 eyes; The visual acuity remained unchanged in 19 eyes(40%)and decreased in 3 eyes(6%). 40 eyes of 40 cases did not use any intraocular pressure lowering drugs, the intraocular pressure <21mmHg and the complete success rate was 85% at the 6mo follow up post-operatively. The intraocular pressures were 15.6±6.2, 12.8±5.9, 14.7±5.3, 17.1±6.9, 18.3±6.7mmHg at 1, 7d, 1, 3 and 6mo after compound trabeculectomy, which were different from the intraocular pressure at admission(46.0±11.9mmHg)and intravitreal intraocular pressure(39.9±12.5mmHg)after 3d of intravitreal injection of conbercept were significantly different(F=106.65, P<0.001). Hyphema occurred in 3 eyes after compound trabeculectomy, and completely absorbed within 3-7d after conservative drug treatment.

CONCLUSION: Intravitreal injection of conbercept combined with compound trabeculectomy and retinal photocoagulation is safe and effective in the treatment of neovascular glaucoma.
