Abstract： 目的观察放射状视神经切开术(RON)治疗视网膜中央静脉阻塞(CRVO)的临床效果.方法回顾分析5例经平坦部玻璃体途径行RON治疗的CRVO患者的临床资料.其中,2例患者手术前确诊为CRVO,手术前后分别进行视力、眼底照相、荧光素眼底血管造影(FFA)、彩色超声多谱勒(CDI)血流扫描、电脑视野及光相干断层扫描(OCT)等检查;3例患者因玻璃体积血接受手术治疗,手术中确诊为CRVO所致.5例均有明显黄斑水肿.对比观察患者手术前后视力、眼底检查及手术后眼底照相和OCT检查结果.手术后随访12个月.结果除1例患者视力下降外,其余4例患者视力均有不同程度提高.眼底照相和(或)FFA、OCT检查显示手术后1个月时黄斑水肿均明显消退,手术后2个月时眼底出血基本吸收,1例行视野检查者显示手术后视野改善.1例手术后出现玻璃体积血,2例手术中穿刺视盘时出血.结论RON可有助于CRVO患者改善患眼黄斑水肿,减少眼底出血,防止新生血管形成,并能一定程度地提高视力,对治疗CRVO具有一定可行性及临床价值.但尚需要较大规模、多中心的随机临床对照观察来进一步研究证实.
