Clinical observation on the efficacy of intravitreal injection of conbercept in the treatment of macular edema

Abstract

Objective To observe the efficacy of intravitreal injection of conbercept in the treatment of macular edema secondary to branch retinal vein occlusion. Methods The data of 33 eyes of 33 patients with macular edema secondary to retinal branch vein occlusion (BRVO-ME) from Jan.2018 to Dec.2018 were retrospectively analysed. The followed-up time was 3 months. Results BCVA(logMAR) were improved at 1, 2, and 3 months after injection, and the difference were statistically significant between before and each time after injection(Z=4.948, 4.642, 4.305, P=0.000, 0.000, 0.000). Central macular retinal thickness (CMT) decreased at 1, 2, and 3 months after injection, and the difference were statistically significant(Z=4.315, 4.404, 4.387, P=0.000, 0.000, 0.000). Conclusion Intravitreal injection of conbercept can improve vision and reduce macular edema in the treatment of retinal branch vein occlusion secondary to macular edema in a short period of time.
