A 62-year-old man reported 6 stereotyped attacks of transient loss of vision in the lateral visual field of the right eye and was subsequently found to have right internal carotid artery occlusion. Fundoscopy revealed an anomalous central retinal artery branching whereby a single stem vessel supplied the superior and inferior nasal quadrants of the retina. Circulatory insufficiency in this anomalous stem could explain the occurrence of vertical monocular hemianopsia as an unusual manifestation of ipsilateral carotid artery atherosclerosis.
一名62岁男性报告右眼外侧视野出现6次刻板发作的短暂性视力丧失，随后被发现右侧颈内动脉闭塞。眼底检查发现视网膜中央动脉分支异常，即由单一主干血管供应视网膜的鼻上象限和鼻下象限。这种异常主干血管的循环功能不全可以解释垂直性单眼偏盲的发生，这是同侧颈动脉粥样硬化的一种不寻常表现。
