Long-term Outcome of Laser Photocoagulation Combined with Ranibizumab Intravitreal Injection in Macular Edema Secondary to Retinal Vein Occlusion
To investigate the efficacy of laser photocoagulation combined with ranibizumab intravitreal injection in macular edema secondary to retinal vein occlusion in long term.35 eyes with branch retinal vein occlusion (BRVO) and 37 eyes with central retinal vein occlusion (CRVO) treated with or without laser combined with ranibizumab were investigated in this retrospective study. Laser was conducted 7-10 days after the third ranibizumab injection if fluorescein angiography showed ischemic area. In BRVO, patients may receive both macular grid and local peripheral retinal laser. In CRVO, patients just received peripheral retinal laser. We estimated the changes in visual acuity, central retinal thickness (CRT), number of injections and laser over 14 months.
