彩色多普勒超声对糖尿病视网膜病变眼血流动力学与颈动脉关系的研究

目的通过彩色多普勒超声对糖尿病视网膜病变患者眼血流动力学及颈动脉改变进行研究。方法选择120例患者，分为糖尿病病例组与对照组，进行彩色多普勒检查，比较两组患者视网膜中央动脉、眼动脉及颈动脉的血流动力学情况。结果（1）与对照组（D组）比较，糖尿病病例组中无视网膜病变组（A组）、伴背景型视网膜病变组（B组）、伴增殖型视网膜病变组（C组）视网膜中央动脉Vs、Vd减低，RI增高。（2）与对照组比较，A组、B组眼动脉Vs、vd减低，RI增高。（3）与对照组比较，A组、B组、C组Ds减低，IMT增高。结论采用彩色多普勒对糖尿病眼动脉、视网膜中央动脉及颈动脉进行测定，可早期发现血流参数的改变，对视网膜病变的防治起重要作用。

A clinical study on haemodynamics of ocular and carotid artery in patients with diabetic retinopathy by CDFI

Objective To research the hemodynamic and carotid artery Through the color doppler ultrasonography in patients with diabetic retinopathy. Methods Choose 120 cases of patients, divided into diabetes group and controls group, carry on color Doppler exam, compare two group patients with the haemodynamics of the Central retinal artery, Ophthalmic artery and Carotid artery. Results （ 1 ） Compared with the control group, Vs,Vd of Central retinal artery in group A, B and C is lower than the control group, RI is higher than the control group. （ 2 ） Compared with the control group, Vs, Vd of Ophthalmic artery in group A,B is lower than the control group, RI is higher than the control group. （3）Compared with the control group, Ds of group A,B and C is lower than the control group, IMT is higher than the control group. Conclusion By color doppler to diabetes Ophthalmic arteries, central retinal artery and carotid artery can be determined, the change of the blood flow parameters found early, to the prevention and control of retinopathy plays an important role.
