摘要
目的：应用彩色多普勒超声研究白内障患者眼部血管的血流动力学改变。方法：将60例白内障患者分为2组，30例单纯患白内障（Ⅰ组）及30例白内障合并糖尿病和/或高血压（Ⅱ组）。与30例健康者作为对照组（Ⅲ组）进行比较，分别检测眼动脉（OA）、睫状后动脉（PCA）及视网膜中央动脉（CRA）的收缩期血流速度（Vs）、舒张末期血流速度（Vd）及血管阻力指数（RI）。结果：Ⅱ组中OA、PCA、CRA的Vs、Vd均明显减低，血管RI均明显增高，血流频谱呈低流速高阻力状况，与Ⅲ组比较差异有统计学意义（P<0.05）。Ⅰ组中OA、PCA、CRA的Vs、Vd及血管RI血流频谱均无明显变化，与Ⅲ组比较差异无统计学意义（P>0.05）。结论：眼部血管的血流动力学改变与患白内障无关，与患糖尿病、高血压有关。应用彩色多普勒超声能够准确反映白内障患者眼部血管的血流动力学改变情况，它为临床提供重要参考价值。
Abstract
Objective: To explore ophthalmic vascular hemodynamic changes with color Doppler ultrasound in patients with cataract. Methods: 60 patients with cataract were divided into 2 groups, 30 cases with simple cataract(group Ⅰ) and 30 cases with cataract mergeing diabetes mellitus and/or hypertension(group Ⅱ). 30 cases of healthy volunteers was as the control group(group Ⅲ). Detected in ophthalmic artery(OA) and posterior ciliary artery(PCA) and central retinal artery(CRA) systolic blood flow velocity(Vs), end-diastolic blood flow velocity(Vd) and resistance index(RI). Results: The systolic blood flow velocity (Vs) and end-diastolic blood flow velocity(Vd) of OA, PCA, CRA of group Ⅱ were significantly lower, vascular RI were significantly increased, the condition of low velocity and high resistance of blood flow spectrum. There was statistically significant difference compared with group Ⅲ(all P<0.05). Vs, Vd and vascular RI of OA, PCA, CRA of group Ⅰ were no obvious changes of blood flow spectrum. There was no statistically significant difference compared with group Ⅲ(all P>0.05). Conclusions: Eye vascular hemodynamics change associated with diabetes and hypertension, not cataracts. Application of color Doppler ultrasound can accurately reflect the changes of ocular vascular hemodynamics in patients with cataract and provides an important reference for clinical value.
