摘　　要：目的:通过彩色多普勒超声观察糖尿病眼球后血管的血流动力学,研究其诊断价值。方法:共用彩色多普勒超声检查了正常人眼球、糖尿病视网膜病变(diabetic retinopathy,DR)及有糖尿病但无糖尿病视网膜病变(non-diabeticretinopathy,NDR)眼球的球后血管并与荧光素眼底血管造影及检眼镜对比。结果:随着DR的进展,糖尿病患者眼球后血管血流动力学改变的趋势是眼球后动脉的血流速度下降,阻力升高;球后静脉流速增高伴搏动性增强。结论:彩色多普勒超声技术为定量评价DR,判断其预后提供了重要的参考价值。Objective： To observe the hemodynamic changes of retroocular and evaluate the diagnostic valuation of color Doppler ultrasound in diabetes.Methods： Retroocular hemodynamics were measured in normal and diabetic retinopathy（DR） and non-diabetic retinopathy（NDR） on color Doppler flow imagining and compared with fundus fluorescein angiography（FFA） and Ophthalmoscope.Results： In the progress of DR,the flow’s decrease and the resistance’s increase of retroocular artery were detected in this research,the increase of flow and pulsatility index of retroocular vein were observed too.Conclusion： Color Doppler ultrasound is of important reference value for not only prognosis but also quantitative analysis of diabetic retinopathy.
