RESUMEN
@#AIM: To investigate the effect of panretinal photocoagulation(PRP)combined with intravitreal injection of conbercept as an adjuvant to neovascular glaucoma secondary to central retinal vein occlusion(CRVO). <p>METHODS: This was a prospective case-control study. Patients diagnosed with neovascular glaucoma(stage Ⅰor Ⅱ)secondary to CRVO in our hospital from January 2014 to March 2019 were enrolled and randomly divided into two groups. Patients in combination group were treated with both PRP and intravitreal conbercept injection. In the other group(PRP only group)patients were treated with PRP only. Changes of best corrected visual acuity(BCVA), intraocular pressure(IOP)and iris neovascularization(NVI)were observed before treatment, 1wk, 1mo, 3mo, 6mo and 9mo after treatment.<p>RESULTS: Sixty patients 60 eyes were enrolled, with the mean age of 54.45±6.08 years. 56.67% were males. There were no significant difference between two groups in age and gender. After treatment, all the indexes of the two groups improved obviously with significant different(<i>F</i>=154.992, 92.519, 30.696, 82.374, all <i>P</i><0.001), visual acuity improved, IOP decreased, and NVI decreased at different time points. The difference was statistically significant compared with the control group one week after treatment(<i>F</i>=50.870, 24.265, 13.125, 11.829, all <i>P</i><0.001), and it was maintained continuously.<p>CONCLUSION: For eyes with CRVO secondary with neovascular glaucoma, intravitreal injection of conbercept combined with panretinal photocoagulation PRP is better than panretinal photocoagulation PRP only.
