应用彩色多普勒血流显像（ＣＤＦＩ），检测４０例非胰岛素依赖型糖尿病（ＮＩＤＤＭ）患者的眼动脉（ＯＡ）血流动力学参数。结果表明：ＮＩＤＤＭ患者ＯＡ血流呈低流速、低流量、高阻力型；血流动力学参数中，血管阻力指数（ＲＩ）增高，而舒张末期血流速度（Ｖｄ）降低；糖尿病视网膜病变（ＤＲ）患者改变更明显；糖尿病病程≥５年、合并高血压者改变明显，差异均有显著性（Ｐ＜０．０５）。因此，ＲＩ和Ｖｄ是反映ＯＡ血流动力学的基本指标。ＮＩＤＤＭ患者ＣＤＦＩ检测可动态观察ＯＡ的血流动力学的改变，早期发现ＤＲ，并为ＤＲ的治疗提供客观依据。
Color Doppler flow imaging (CDFI) was used to measure the hemodynamics of ophthalmic artery (OA) in 40 patients with non-insulin dependent diabetes mellitus (NIDDM). The results showed that in patients with NIDDM, the blood flow velocity of OA was low flow rate, low flow rate and high resistance type. In the hemodynamic parameters, the vascular resistance index (RI) increased while the end diastolic flow velocity (Vd) decreased. The diabetic retinopathy ) Had more obvious changes in patients. The course of diabetes was more than 5 years and the patients with hypertension had significant changes (P <0.05). Therefore, RI and Vd reflect the basic indicators of OA hemodynamics. CDFI in patients with NIDDM can dynamically observe the hemodynamic changes of OA, early detection of DR, and to provide an objective basis for the treatment of DR.
