A previously healthy 71-year-old woman with hypercholesterolemia and current tobacco use presented with transient painless vision loss in the left eye without other neurologic abnormalities. The 30-second episodes, followed by a recovery, repeated in 2- to 3-minute intervals.¹ Microemboli passing through central retinal artery (CRA) vasculature (Video 1) originated from a complicated atherosclerotic plaque in the left internal carotid artery (Figure). After receiving intravenous thrombolysis 5 hours after symptom onset,² she reported a scotoma in the inferior part of her left eye, which persisted 2 years later. Retinal embolism from carotid artery disease is the most common cause of CRA occlusion.

一名既往健康的 71 岁女性患有高胆固醇血症，目前正在吸烟，左眼出现短暂的无痛性视力丧失，没有其他神经系统异常。30 秒的情节，然后是恢复，以 2 到 3 分钟的间隔重复。¹穿过视网膜中央动脉 (CRA) 脉管系统的微栓子（视频 1）源自左侧颈内动脉中的复杂动脉粥样硬化斑块（图）。症状出现 5 小时后接受静脉溶栓治疗后，²她报告左眼下部出现暗点，2 年后仍持续存在。颈动脉疾病引起的视网膜栓塞是 CRA 闭塞的最常见原因。
