摘　　要：目的 探索糖尿病及视网膜血管炎的血流动力学改变。方法 对16例正常人(32只眼)、16例糖尿病(32只眼)以及16例视网膜血管炎(32只眼)的中央动脉(CRA)、睫状后动脉(PCA)和眼动脉(OA)进行彩色多谱勒(CDFI)检查。应用CDFI技术分别测量了搏动指数(PI)和阻力指数(RI)。结果 糖尿病组的PI和RI测值均明显高于正常对照组(P<0.01)。而视网膜血管炎组与对照组比较则无显著差异(P>0.01)。此外,眼底检查糖尿病眼底未有血管改变的,PI和RI也明显增加,表明CDFI检查血流动力学改变早于眼底镜下改变。结论 CDFI检查眼底血管是一种既可靠又准确且能早期观察糖尿病微血管病变的有效方法。Objective To study the ocular blood flow in diabetes and retinal vasculitis.Methods Blood flow dynamics of the central retinal artery ( CRA), post ciliary and ophthalmic arteries were observed in 16 normal subjects and 16 patients with diabtes,and 16 patients with retinal vasculitis using CDFI.Results The significant diffrerences of PI and RI values between normal control and diabetes were reflected by blood flow waveforms. The results showed that abnormal ocular blood flow waveforms appeared prior to the typical retinal vascularity changed on ophalmofundoscope, but no marked difference between retinal vasculitis and normal groups. Conclusions CDFI is an effective method neither reliable nor precise and can inspect diabetic retinopathy early.
