| 摘 要： | 应用彩色多普勒检测了２２例正常人４４只眼和２２例糖尿病患者３５只眼的眼动脉（ＯＡ）、视网膜中央动脉（ＣＲＡ）及睫状动脉（ＰＣＡ）的血流频谱形态和血流动力学特点。结果表明：糖尿病组的峰值流速（ＰＳ）和舒张末期流速（ＥＤ）均明显低于正常对照组（Ｐ＜０．０１），而阻力指数（ＲＩ）明显高于正常对照组（Ｐ＜０．０１），呈低流速高阻力型血流状态。其中１６只眼眼底镜检查未见有血管改变的血流动力学和频谱形态也发生改变。提示应用彩色多普勒血流显像（ＣＤＦＩ）检查眼部血管是一种既可靠又准确且能早期观寨糖尿病微血管病变的有效方法。

| Abstract: | The ophthalmic artery(OA), centralretinal artery (CRA), and posterior ciliary artery(PCA) of 44 healthy controls and 35 diabetic patients were examined by CDFI and those Dopplerspectra and now characteristics were observed. Theresults showed that PS and ED were significantlylower in the diabetics than that of the control, andRI was significantly higher in diabetics than that ofthe control. The changes of Doppler spectra andflow characteristics were discovered in 16 normal orbits which were examined on ophalmofundscope.We suggests that CDFI is a reliable and accurate diagnosis method for early diabetic microvessel disease. |
