【摘要】 目的　研究视网膜中央静脉阻塞患者眼动脉、睫状后短动脉、视网膜中央动脉和视网膜中央静脉血流动力学变化及其意义。方法　采用美国 Acuson公司 Sequoia5 12型彩色电脑超声诊断仪 ,检测视网膜中央静脉阻塞患者患侧 17眼 ,健侧 17眼及正常对照 6 4眼眼动脉、睫状后短动脉、视网膜中央动脉收缩期峰值流速 ,舒张末期流速、搏动指数、阻力指数和视网膜中央静脉的最大血流速度。结果　视网膜中央静脉阻塞患者患侧眼动脉、睫状后短动脉、视网膜中央动脉的收缩期峰值流速、舒张末期流速明显低于正常对照组 ,而搏动指数、阻力指数明显高于正常对照眼 ;视网膜中央静脉阻塞患者患眼视网膜中央静脉的最大血流速度明显低于健眼 ,健眼睫状后短动脉、视网膜中央动脉的收缩期峰值流速、舒张末期流速明显低于正常对照组。结论　视网膜中央静脉阻塞患者眼血流动力学明显异常 ,彩色多普勒技术可作为研究其血流动力学指标的重要方法更多还原

【Abstract】 Objective To investigate the changes of ocular hemodynamics in patients with central retinal vein occlusion(CRVO).Methods The hemodynamic parameters (PSV, EDV, PI, RI) of OA, PCA and CRA, Vmax of CRV were measured in the involved eyes (n=17) with CRVO and the contralateral clinically healthy eyes (n=17) and in the controlled eyes (n=64) by Color Doppler Flow Imaging (Acuson Sequoia 512).Results In the involved eyes with CRVO, PSV, EDV were significantly lower than those in controlled eyes, PI and RI were significantly higher than those in controlled eyes, Vmax of CRV were significantly lower in the CRVO involved eyes compared with the contralateral clinically healthy eyes, PSV and EDV of PCA, CRA of the contralateral clinically healthy eyes were significantly lower than those in controlled eyes. Conclusion The ocular hemodynamics in the involved eye of central retinal vein occlusion are abnormal significantly. Color Doppler Flow Imaging can be regarded as an important method in studying the hemodynamics parameter of CRVO.更多还原
