A common carotid artery occlusion (CCAO) is very rare and the clinical features of CCAO have rarely been described. Since the blood supply of the eye and orbit is derived from the internal carotid artery, a CCAO may present with various ophthalmological symptoms, ranging from incidental findings to complete visual loss but also other neuro-ophthalmological abnormalities.
A 61-year-old woman presented with acute monocular vision loss and an elevation deficit of the right eye. Fluorescein angiography showed delayed filling of both the retinal and choroidal vasculature, without occlusion/embolisms of the retinal arteries. Vascular imaging showed a right CCAO.
CCAO has a variable presentation. In patients with acute unilateral visual loss a CCAO should be considered, especially when ocular motility deficits are present. Fluorescein angiography examination can aid in the localization and diagnosis of the vascular insult. Urgent referral for a systemic work-up is essential.
颈总动脉闭塞（CCAO）非常罕见，其临床特征鲜有描述。由于眼和眼眶的血液供应源自颈内动脉，CCAO可能表现出各种眼科症状，从偶然发现到完全失明，还可能伴有其他神经眼科异常。
一名61岁女性出现急性单眼视力丧失及右眼上睑下垂。荧光素血管造影显示视网膜和脉络膜血管系统充盈延迟，视网膜动脉无阻塞/栓塞。血管成像显示右侧颈总动脉闭塞。
CCAO表现多样。对于急性单侧视力丧失的患者，应考虑CCAO，尤其是存在眼球运动障碍时。荧光素血管造影检查有助于血管损伤的定位和诊断。紧急转诊进行全面的系统检查至关重要。
