彩色多普勒血流显像预测2型糖尿病视网膜早期病变的应用价值

Application of Color Dopple Flow Imaging on early Type 2 diabetic retinopathy

目的探讨彩色多普勒血流显像(CDFI)对眼底尚无改变糖尿病患者视网膜中央动脉(CRA)血流动力学变化的诊断价值。方法利用CDFI对42例(84只眼)糖尿病人和18例(36只眼)正常对照者的视网膜中央动脉血流进行检测。结果糖尿病患者视网膜中央动脉收缩期峰值流速(PS)、舒张期峰值流速(ED)均低于正常对照组(P<0.05);搏动指数(PI)、阻力指数(RI)均高于对照组(P<0.01)。结论彩色多普勒血流显像是检测无眼底改变糖尿病患者CRA血流动力学变化的有效诊断方法。

[Objective] To evaluate the diagnosis value of Color Dopple Flow Imaging （CDF1） in the hemodynamie changes of central retinal artery （CRA） in the diabetic patients without orbital lesions. [Method] The CRA of 84 eyes of patients with diabetic meUitus and 36 eyes of healthy control cases wore examined using CDFI. [Result] The IX3, ED of CRA in diabetic patients are lowr than that in the control group cases （P 〈0.05）, while the PI, RI are higher （P 〈0.01）. [ Conclusion] CDFI is effective diagnosis method for the hemoclyamic changes of CRA in the diabetic patients without orbital lesions.
