摘要： 目的探讨高频彩超诊断视网膜中央动脉硬化的临床应用可行性。方法对210例缺血性脑血管病患者(420只眼)和80例正常对照者(健康体检者,160只眼)采用彩色多普勒超声仪检测双侧视网膜中央动脉血流频谱,测量收缩期最大血流速度峰值(PSV)、舒张期末血流速度(EDV)及阻力指数(RI)。结果正常组视网膜中央动脉血流频谱图形呈三峰二谷或斜三角形;脑血管病患者频谱形态发生改变,收缩期、舒张期血流速度较正常对照组缓慢,RI值显著增大(P<0.05～0.001)。结论缺血性脑血管病患者视网膜中央动脉血流速度较健康人缓慢,RI值增大;高频彩超可用于视网膜中央动脉硬化的诊断。

Abstract: Objective To explore the feasible of diagnosing ischemic cerebrovascular diseases by detecting central retina artery sclerosis(CRA) with color Doppler ultrasonography.Methods210 patients with ischemic cerebrovascular disease(420 eyes) and 80 healthy volunteers(160 eyes) were examined by color Doppler flow imaging(CDFI) to detect double sides blood frequency spectrum of CRA and hemodynamic parameters of CRA including peak systolic velocity(PSV),end of diastolic velocity(EDV)and resistant index(RI).ResultsThe blood frequency spectrum of CRA showed three apices and two vales or slanting triangle in healthy volunteers.But in patients with ischemic cerebrovascular disease,the blood frequency spectrum changed,and PSV and EDV were slower and RI increased compared with those in the healthy volunteers(PP<0.05～0.001).ConclusionIn patients with ischemic cerebrovascular disease,the blood flow of CRA is slower and RI increases compared with health individuals.The color Doppler ultrasonography can used for diagnosis of CRA sclerosis.
