摘　　要：目的:通过彩色多普勤对糖尿病视网膜中央动脉血流参数的检测,寻找早期诊断糖尿病视网膜病变的敏感指标。方法:利用彩色多普勒超声诊断仪,对108例胰岛素依赖型糖尿病患者和60例健康者进行视网膜中央动脉血流参数检测并作对比分析。结果:（1）糖尿病患者视网膜中央动脉的收缩末期血流速度（ESV）、舒张末期血流速度（EDV）明显低于对照组,ESV为 9.06±1.76cm/s:10.4±2.4cm/s,EDV为3.32±0.76cm/s:4.58±1.76cm/s,P均<0.01;（2）糖尿病组搏动指数（PI）、阻力指数（RI）均高于对照组,但均无显著差异。结论:糖尿病患者视网膜出现病理改变之前,血流参数ESV、EDV已发生明显改变,是检测糖尿病视网膜早期病变的敏感手段。Objective: Examination of the central artery of retina in patients with diabetes was executed. look for thesensitive diagnostic index of early retina pathological change in patients with diabetes. Methods:The blood parameters of the central artery of retina in patients with diabetes were inspected by color Doppler ultrasonography. Results: The blood parameters of patient with diabetes were different from those in normal control group, end-systolic velocity of blood flow (ESV) and end-diastolic velocity of blood flow (EDV) significantly increased (P<0. 01), resistent index (RI) and pulsitive index (PI) slightly increased (P>0. 05). Conclusion: ESV and EDV have already obvious abnormal change before the retina to appear the pathology changes. It is sensitive index to examine the pathological change of retina in patients with diabetes. .
