Abstract:
Objectlve To assess the clinical effects and safety of intravitreal injection of conbercept and macular photocoagulation for non-ischemic macular edema secondary to branch retinal vein occlusion (BRVO).Methods A total of 50 patients (50 eyes) with non-ischemic macular edema following BRVO were retrospectively analyzed.Patients were divided into 2 groups:ICI group (26 eyes) received intravitreal injection of conbercept,laser group (24 eyes) received standard-of-care grid laser for macular edema.The best-corrected visual acuity (BCVA) and central macular thickness (CMT) were observed before and 1 week,1 month,2 months and 3 months after treatment.Then,the changes in pre-treatment and post-treatment were compared,and the related complications were recorded.Results The difference of BCVA before treatment was not significant between two groups (P > 0.05).BCVA at 1 week,1 month,2 months and 3 months after treatment in two groups were all improved,the differences were statistically significant compared with before treatment (all P < 0.05),and the differences were statistically significant between two groups after treatment (all P <0.05).At 3 months after treatment,BCVA of 18 patients (69.23%) in ICI group and 8 patients (33.33%) in ICI group improved 2 lines.The difference of CMT before treatment was not significant between two groups (P > 0.05),CMT at 1 week,1 month,2 months and 3 months after treatment in two groups were all decreased,the differences were statistically significant compared with before treatment (all P < 0.05),and the differences were statistically significant between two groups after treatment (all P <0.05).13 eyes received repeat intravitreal injection in ICI group,including 2 eyes at 1 month,7 eyes at 2 months with CMT >250 μm,and 3 eyes at 3 months.No severe side effect related with drug and intravitreal injection occurred in the two groups.Conclusion Mean BCVA change and CMT change are significantly greater in the intravitreal injection of conbercept than the standard-of-care grid laser group for the macuiar edema secondary to non-ischemic BRVO.
