Background and Importance: Additional time is needed to determine the exact impact of COVID-19 on acute cerebrovascular disease incidence, but recently published data has correlated COVID-19 to large vessel occlusion strokes. Clinical Presentation: We report the first case of central retinal artery occlusion (CRAO) as the initial manifestation of COVID-19 infection. Subsequent neuroimaging revealed a large thrombus extending into the internal carotid artery. Conclusion: This case illustrates the need to suspect COVID-19 infection in patients presenting with retinal arterial occlusion, including individuals who are asymptomatic or minimally symptomatic for COVID-19 infection.

单眼视力丧失是 COVID-19 感染的主要症状

背景和重要性：需要更多时间来确定 COVID-19 对急性脑血管病发病率的确切影响，但最近发表的数据已将 COVID-19 与大血管闭塞性卒中相关联。临床表现：我们报告了第一例视网膜中央动脉闭塞 (CRAO) 作为 COVID-19 感染的初始表现。随后的神经影像学检查显示有一个大血栓延伸到颈内动脉。结论：该病例表明有必要怀疑出现视网膜动脉阻塞的患者感染 COVID-19，包括无症状或症状轻微的 COVID-19 感染患者。
