颈动脉闭塞可以引起眼眶血流减少,产生缺血性眼病。眼球前部病变包括巩膜充血、角膜混浊、瞳孔中度扩大,对光反应迟钝或消失、虹膜炎及眼压异常;眼球后部病变包括缺血性视网膜病变、静脉淤血性视网膜病以及眼球动力值减低。本文介绍6例缺血性眼病并经颈动脉造影证实颈动脉闭塞。6例均有视力障碍、患眼视野有不同程度缺损、瞳孔对光反应迟钝成丧失、眼压2例减低4例增高;4例同时伴有一侧肢体感觉或运动障碍。全部病例均有眼底改变(视网膜静脉扩张、火焰状出血、视乳头苍白等等),患眼动力学测定眼动脉压减低;颈动脉造影证明双侧颈内动脉闭塞者2例,右侧颈内动脉狭窄达95%者1例,左颈总动脉闭塞1例,其余2例为一侧颈内动脉闭塞。4例发现眼压增高,Smith报导两
Carotid artery occlusion can cause orbital blood flow reduction, resulting in ischemic eye disease. Anterior eye lesions include scleral hyperemia, corneal opacity, moderate expansion of the pupil, slow or disappear light response, iris and intraocular pressure abnormalities; posterior eye diseases including ischemic retinopathy, venous congestion retinal disease and ocular motility value reduce. This article describes 6 cases of ischemic eye disease and confirmed by carotid artery carotid artery occlusion. All of the 6 cases had visual impairment, with varying degrees of visual field defect, loss of pupillary response to light, loss of intraocular pressure in 2 cases and elevation of 4 cases, and 4 cases with limb sensation or dyskinesia on one side. All patients had fundus changes (retinal vein dilatation, flaming bleeding, optic disc pale, etc.), ocular arterial ophthalmic arterial pressure measurement decreased; carotid artery angiography showed bilateral internal carotid artery occlusion in 2 cases, the right side of the neck In 95% of patients with arterial stenosis in 1 case, left common carotid artery occlusion in 1 case, and the remaining 2 cases of one side of the internal carotid artery occlusion. 4 cases found that intraocular pressure increased, Smith reported two
