彩色多普勒成像技术对高血压患者眼部血流动力学研究

目的:了解高血压患者的眼部血流动力学。方法:应用彩色多普勒成像技术(color Doppler image,CDI)对71例142眼高眼压患者的眼动脉(ocular artery,OA)、视网膜中央动脉(central retinal artery,CRA)和睫状后短动脉(short posterior ciliary artery,SPCA)的血流动力学指标进行检测,并取无高血压的健康人30例作为对照组。结果:高血压患者眼血管血流速度减慢,阻力指数(resistance index,RI)明显增高,呈低流速高阻力状况。结论:本研究可较准确地反映外周血管的阻力和血供情况,对高血压病的疗效观察和预后评估有重要意义。

Color Doppler imaging analysis of the ocular hemodynamics in patients with hypertension

AIM:To assess the ocular hemodynamics in patients with hypertension. ·METHODS: This study included 71 patients(142 eyes) with hypertension.The hemodynamics criteria of the ocular artery (OA),central retinal artery (CRA) and short posterior ciliary artery(SPCA) were measured by color Doppler image(CDI). Thirty patients without hypertension were taken as control group. ·RESULTS: The ophthalmic bloodstream speed decreased,and resistance index (RI) increased obviously.The ophthalmic blood vessels of hypertension were in a state of low bloodstream and high resistance. ·CONCLUSION: The examination of ophthalmic vascular ultrasound,which can accurately reflect the peripheral vascular resistance and the blood supply,is of great significance to the observation of curative effect and the assessment of prognosis.
