摘　　要：目的检测眼球缺血综合征(OIS)患者颈总动脉、颈内动脉狭窄程度及眼动脉、视网膜中央动脉收缩期血流速峰值(peaksystolicvelocity,PSV),了解其眼部血供特点,通过与正常对照组比较,对其眼血流动力学改变进行探讨。方法应用彩色多谱勒超声成像技术对比研究OIS患者组和正常对照组颈总动脉、颈内动脉、眼动脉、视网膜中央动脉收缩期血流速峰值(PSV)。结果研究组患侧眼动脉PSV为(24.36±5.80)cm/秒,对侧PSV为(30.74±11.00)cm/秒,正常对照组(29.59±4.15)cm/秒,患侧眼动脉PSV明显降低(P<0.05)。研究组患侧视网膜中央动脉PSV为(6.83±2.22)cm/秒,对侧为(10.84±1.00)cm/秒,正常对照组为(11.28±2.42)cm/秒,患侧视网膜中央动脉PSV明显降低(P<0.05)。结论1.眼动脉、视网膜中央动脉收缩期血流速峰值降低是眼球缺血综合征发病的重要机制。2.彩色多谱勒超声成像技术对于定量评价眼球缺血综合征眼部主要血管的血流动力学改变有重要意义。Objective To measurement the peak systolic velocity（PSV） in the common carotid artery and the internal carotid artery and ophthalmic artery and central retinal artery,in order to observe the feature of ocular hemodynamic, and to study the change of hemodynamic in OIS. Methods The patients of study group and normal control group underwented color doppler imaging for the measurement of the peak systolic velocity（PSV）in the common carotid artery and the internal carotid artery and ophthalmic artery and central retinal artery.The results were compared in order to study the mechanism on ocular ischemia. Results The PSV in ipsilateral ophthalmic artery was （24.36±5.80）cm/s.The values were reduced as compared with values of other side and normal group[（30.74±11.00）cm/s and （29.59±4.15） cm/s],P〈0.05. The PSV in ipsilateral central retinal artery was （6.83±2.22） cm/s. The values were reduced as compared with values of other side and normal group[（10.84 ±1.00）cm/s and （11.28±2.42） cm/s],P〈0.05. Conclusion 1. Ocular ischemic syndrome was due to the perfusion defecency of central retinal artery leading by the reduce of peak systolic velocity in the ophthalmic artery and the retinal central artery. 2.Color doppler imaging has value in quantitating hemodynamic characteristics of the retrobulbar major vessels in OIS.
