目的:研究前部缺血性视神经病变(anterior ischemic optic neuropathy,AION)与颈动脉狭窄的相关性。方法:回顾性总结和分析2007-01/2010-10在我院住院治疗的56例62眼AION患者的视力、眼底、视野、荧光眼底血管造影、头颅CT、双侧颈动脉彩色超声多普勒(CDFI)等检查资料,探讨AION与颈动脉狭窄的关系。结果:共56例62眼经过眼底、视野、FFA检查,头颅CT排除颅内占位性病变,均确诊为AION。其中高血压36例(64%),糖尿病29例(52%),其中高血压并糖尿病17例;高血脂23例(41%),其中高血压并高血脂11例,糖尿病并高血脂4例。患者行双侧颈动脉CDFI检查,发现颈动脉粥样硬化斑块,存在不同程度的狭窄者30例(54%)。结论:AION与颈动脉狭窄具有密切的相关性,临床对于AION行双侧颈部CDFI检查了解颈动脉有无狭窄是非常必要的。

·AIM:To investigate the correlation between anterior ischemic optic neuropathy(AION)and carotid artery stenosis.METHODS:All of 56 inpatients 62 eyes from Jan.2007 to Oct.2010 were retrospectively analyzed.The visual acuity,ocular fundus,visual field,fundus fluorescein angiography(FFA),CT and carotid color Doppler flow imaging(CDFI)were checked to explore the correlation between AION and carotid artery stenosis.RESULTS:All patients were diagnosed with AION.Among 56 patients,36 patients(64%)were with high blood pressure;29 patients(52%)were with diabetics;23 patients(41%)were with hyperlipemia;30 patients(54%)were with carotid artery stenosis for atherosclerosis.CONCLUSION:There is strong correlation between carotid artery stenosis and AION.It is necessary to examine carotid atrery stenosis with carotid CDFI for patients with AION.
