Abstract Objective: To assess the efficacy of single intravitreal injection of ranibizumab with laser photocoagulation for the treatment of macular edema secondary to branch retinal vein occlusion (BRVO). Methods: In this retrospective study, 52 patients (52 eyes) during June 2014 to December 2016 at Taizhou Municipal Hospital with macular edema secondary to BRVO were diagnosed by fundus fluorescence angiography. The patients were divided into two groups, one receiving laser photocoagulation alone and the other receiving a single intravitreal injection of ranibizumab. The injection group was further divided into two groups,one receiving the injection before laser therapy and one receiving afterwards. The best corrected visual acuity (BCVA) and central macular thickness (CMT) were recorded before the therapy and at one and six
months afterwards. Repeated measurement analysis of variance, one-way analysis of variance, and paired t-tests were used to analyze the data. Results: Before the therapy, and at one and six months after therapy,the total difference of BCVA among the three groups was statistically significant (F=18.28, P=0.011).Objective: To assess the efficacy of single intravitreal injection of ranibizumab with laser photocoagulation for the treatment of macular edema secondary to branch retinal vein occlusion (BRVO).
