颈动脉粥样硬化常发生一过性脑缺血发作和卒中。但眼部症状在临床上常作为重要监测项目,其中最常见的是一过性黑蒙,即突然单眼失明,几秒或几分钟内自行恢复。此现象常归咎于视网膜血管血栓,但颈动脉血流动力学改变造成单侧视网膜血流量减少也可出现单眼一过性管状视野或失明。亮光刺激这类病人的眼睛也能引起暂短的单限失明,即所谓亮光黑蒙。作者报告2例病人经颈外动脉再通术解除此症状。例1,男,59岁.6个月来右眼视力障碍,每天约出现3次,多发生在迅速变换体位时,尤其是走出室 Carotid atherosclerosis often occurs in transient ischemic attacks and strokes. However, eye symptoms are often used as important monitoring items in clinical practice. The most common one is transient amaurosis, which is sudden monocular blindness and self-recovery in seconds or minutes. This phenomenon is often blamed on retinal vascular thrombosis, but the hemodynamic changes in the carotid arteries caused by unilateral retinal blood flow reduction may also occur monocular transient tubular vision or blindness. Light to stimulate the eyes of such patients can also cause temporary short-term blindness, the so-called light darkness. The authors report two patients with external carotid artery recanalization to relieve this symptom. Example 1, male, 59 years old .6 months to right eye dysfunction, about 3 times a day, occurred in the rapid change of position, especially out of the room
