摘　　要：目的应用声诺维(超声微泡)测定非动脉炎性前部缺血性视神经病变(nonarteritic anterior ischemic optic neuropathy,NAION)患者睫状后动脉血流速度。方法选取经临床确诊的非动脉炎性前部缺血性视神经病变患者28例(33只眼)和正常人28例(28只眼)设为观察组与正常对照组,分别行声诺维造影,观察睫状后动脉的血管分布和和m流速度,并对结果进行统计学分析。结果观察组睫状后动脉血流速度为(2.82±0.88)cm/s.正常组睫状后动脉m流速度为(4.90±1.00)cm/s,差别具有统计学意义(P<O.01)。结论本实验为临床诊断非动脉炎性前部缺血性视神经病变及评价睫状后动脉血流状态提供了一种直观的、实时动态的新技术手段,增加了超声诊断非动脉炎性前部缺血性视神经病变的客观性和可行性。Objective To test the blood flow velocity of posterior ciliary artery of patients with nonarteritic ante- rior ischemic optic neuropathy（NAION）by SonoVue （ultrasound microbubble）. Methods SonoVue was performed on 28 NAION patients （33 eyes） with the clinically diagnosed and 28 normal cases （28 eyes） as control The distribution, status and the flow velocity of postciliary artery was observed. Results The flow velocity of posterior ciliary artery of the NAION group was （2.82~0.88） cm/s, and that of normal group was （4.90±1.00） cm/s. All of the result has statistically significant difference （P〈0.01）. Conclusions This study provides a new visualized and real time technol-ogy for the diagnosis of NAION and the evaluation of the flow velocity of posterior ciliary artery, meanwhile it en-hances the objectivity and feasibility of Ultrasonic diagnosis on the nonarteritic anterior ischemic optic neuropathy.
