目的 :应用彩色多普勒显像 (colorDopplerflowimaging ,CDFI)检测糖尿病患者 ,以探讨其血液动力学变化 ,提供有参考价值的数据。方法 :应用CDFI检测了 3 0例糖尿病患者和 50例正常对照组的眼动脉、视网膜中央动脉的收缩期血流峰速、舒张末期流速、平均流速、血管阻力指数和搏动指数。结果 :糖尿病组与对照组比较有 /或无糖尿病视网膜病变 (diabeticretinopathy ,DR)OA和CRA的Vs、Vd降低 (P <0 0 5)、RI增加 (P <0 0 5)。结论 :糖尿病患者的OA和CRA血流速度降低 ,视网膜循环阻力升高 ,视网膜血液供应不良。
OBJECTIVE: To detect diabetic patients by color Doppler flow imaging (CDFI) to explore the hemodynamic changes and provide reference data. Methods: CDFI was used to detect systolic peak flow velocity, end diastolic flow velocity, mean flow velocity, vascular resistance index and pulsatility index in 30 patients with diabetes mellitus and 50 normal controls. Results: Compared with the control group, the Vs and Vd of OA and CRA in diabetic patients and / or diabetic diabetic retinopathy were lower (P <0.05) and RI (P <0.05). Conclusion: The blood flow velocity of OA and CRA in diabetic patients is decreased, the retinal circulation resistance is increased, and the retinal blood supply is poor.
