摘　　要：目的评价相干光断层扫描(OCT)在诊断视网膜中央动脉阻塞(CRAO)中的诊断价值。方法回顾分析经眼底检查、荧光素眼底血管造影(FFA)、OCT确诊的16例(16只眼)CRAO患者的临床资料,所有患者发病2周内。结果眼底检查呈现黄斑区樱桃红改变者10只眼,FFA检查显示12只眼视网膜动脉充盈迟缓,血流呈节段状,16只眼OCT图像均见不同程度的黄斑区视网膜增厚、反射增强、光感受器暗区宽带增大。结论 CRAO具有特征性的OCT表现,对于眼底检查、FFA表现不典型者OCT检查不失为一个快速有效的辅助工具,为临床诊断提供客观依据。Objective To evaluate the role of optical coherence tomography （OCT） in the diagnosis of central ret- inal arterial occlusion （CRAO）. Methods The author retrospectively analyzed the clinical data of 16 eyes diagnosed with CRAO from 16 patients who had a course of CRAO within two weeks. Results There were 10 eyes with cherry red spots on the fovea found in funduscopic examination. The fluorescence fundus angiography （FFA） showed delayed filling of reti- nal artery and blood flow occlusion in 12 eyes. OCT images from all of the 16 eyes revealed increased thickness of macular retina, hyper-reflecfivity of the macula, and broadened photoreceptors region. Condusion CRAO had characteristic man- ifestations on OCT. For CRAO patients without typical results in funduscopic examination and FFA, OCT would be a fast and effective tool to help make a definitive diagnosis.
