The presumed cause of anterior ischemic optic neuropathy is atherosclerotic vascular changes. Small-vessel occlusive vascular disease most likely causes occlusion of one or more posterior ciliary arteries, compromising blood flow to the optic nerve head and choroid. We present the case of a 59-year-old black man with cholesterol emboli within the retinal vasculature combined with a clinical picture of anterior ischemic optic neuropathy and choroidal nonperfusion demonstrated by i.v. fluorescein angiography. We believe this is evidence that, in a rare case, embolic phenomena may be the cause of anterior ischemic optic neuropathy.
前部缺血性视神经病变的推测病因是动脉粥样硬化性血管改变。小血管闭塞性血管疾病很可能导致一条或多条睫状后动脉闭塞，影响视神经乳头和脉络膜的血流。我们报告一例59岁黑人男性病例，其视网膜血管系统内有胆固醇栓子，并伴有前部缺血性视神经病变的临床表现以及经静脉荧光素血管造影显示的脉络膜无灌注。我们认为这是一个罕见病例中栓塞现象可能是前部缺血性视神经病变病因的证据。
