AIM: To appraise the therapeutic effect of dual laser(micro-pulse laser and traditional laser)and single intravitreal injection with conberceptin on macular edema secondary to ischemic branch retinal vein occlusion.METHODS: A prospective cohort study was conducted. 83 patients(83 eyes)participated in the study from November 2017 to November 2018. They were randomly divided into two groups. Group A(42 eyes)accepted the treatment of dual laser and single intravitreal injection with conbercept and group B(41 eyes)accepted only traditional laser treatment and single intravitreal injection with anti-VEGF, and the aim is to analysis the data including BCVA, CMT in follow-up visit after treatment 1, 3, 6mo.RESULTS: After 1mo: in group A, BCVA improved from 0.88±0.11 to 0.43±0.19(PPPPP>0.05). After 3mo: in group A, BCVA raised to 0.13±0.07(PPP=1.00), CMT retained 395.80±34.53μm(P=0.99). The improvement of BCVA and CMT were better in group A(PPP=0.02); in group B, BCVA rebounded to 0.77±0.15(PPPCONCLUSION: The treatment of dual laser and single intravitreal injection with conbercept for macular edema secondary to ischemic branch retinal vein occlusion can maintain good effect more than 3mo.
