摘　　要：目的探讨激光治疗视网膜分支静脉阻塞(Branch Retinal Vein Occlusion,BRVO)的疗效。方法确诊为BRVO并经激光光凝治疗的患者35例(35眼),观察治疗前后的视力、眼底及眼底荧光血管造影(Fundus Fluorescein Angiography,FFA)的变化。结果激光治疗后视力提高者13眼(37%),不变16眼(46%),下降6眼(17%)。初始视力为0.2或更差的患者激光治疗后视力预后较初始视力为0.2以上的患者差。经1-3次光凝治疗,35眼中31眼视网膜出血水肿及新生血管消退,FFA显示渗漏及毛细血管无灌注区消失(88.6%)。无玻璃体出血、新生血管性青光眼、增生性玻璃体视网膜病变等并发症发生。结论激光光凝治疗能加速视网膜出血的吸收,消除黄斑水肿,有助于视力的恢复;初始视力与视网膜分支静脉阻塞的预后密切相关。Objective To study the effect of laser photocoagulation on branch retinal vein occlusion（BRVO）.Methods Changes of visual acuity,ocular fundus and its fluorescein angiography（FFA） in 35 patients（35 eyes） diagnosed as BRVO were observed before and after laser photocoagulation.Results The visual acuity was improved in 13 eyes（37%）,unchanged in 16 eyes（46%） and decreased in 6 eyes（17%） after laser photocoagulation.The prognosis of visual acuity was poorer in patients with their initial visual acuity ≤0.2 than in those with their initial visual acuity 0.2.Retinal hemorrhage and edema as well as angiopoiesis were disappeared in 31（88.6%） out of the 35 eyes after 1-3 times of laser photocoagulation.FFA showed that the leakage at macular area was disappeared with no complications,such as vitreous hemorrhage,secondary neovascular glucoma and proliferative vitreoretinopathy.Conclusion Laser photocoagulation can accelerate the absorption of retinal hemorrhage and eliminate macular edema,thus contributing to the recovery of visual function.Initial visual acuity is closely related with the prognosis of BRVO.
