摘要
目的了解糖尿病及慢性单纯性青光眼患者眼血流动力学的情况，从而为其眼部微循环提供有效的监测手段。方法利用彩色多普勒图像对３０例（６０只眼）糖尿病人，１８例（３６只眼）慢性单纯性青光眼患者及１８例（３６只眼）正常人的眼动脉（ＯＡ）和视网膜中央动脉（ＣＲＡ）的血流动力学进行了测定。同时将糖尿病患者中出现网膜病变（ＤＲ）与未出现病变者（ＮＤＲ）的血流参数进行对照。结果糖尿病和慢性单纯性青光眼患者眼部动脉的收缩期血流速度（ＰＳＶ）和舒张期血流速度（ＥＤＶ）显著低于正常人（Ｐ值分别＜０．０５及＜０．０１）。血管阻力指数（ＲＩ）较正常人高。同时ＤＲ组与ＮＤＲ组比较的结果为前者的ＰＳＶ和ＥＤＶ值明显低于后者（Ｐ＜０．０５）。结论应用彩色多普勒成像（ＣＤＩ）测定糖尿病和慢性单纯性青光眼患者眼血流参数具有一定的临床价值，ＰＳＶ。
Objective To measure the blood flow dynamics of the eyes in the patients with diabetes mellitus and chronic glaucoma using Color Doppler Imaging and to provide an effective method monitoring microcirculation in their eyes.Methods 60 eyes of patients with diabetes mellitus,36 eyes of patients with chronic glaucoma simplex,and 36 eyes of normal adults were examined using CDI.Results The blood flow velocity of ophthalmic artery and central retinal artery of the patients during systolic (PSV)and dialytic (EDV)phases is obviously slower than that in normal adults(P<0.05 and P<0.01).The resistance index of vessels is higher than normal.The PSV and EDV value of the patients with retinopathy is markedly lower than that of the patients without retinopathy (P<0.05).Conclusion Measurement of blood flow parameters in the patients with diabetes mellitus and chronic glaucoma simplex using CDI has some clinical significance.Perhaps PSV and EDV is the most sensitive parameters.
