Non-arteritic ischemic optic neuropathy (NAION) is thought to be caused by loss of blood flow to the optic nerve which in turn causes an acute, unilateral and painless vision loss that affects older vasculopathic patients. We report a case of a 43-year-old Hispanic male with the classic presentation of NAION in the setting of a coronavirus disease 2019 (COVID-19) infection. It is well documented that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can cause hypoxemia and thrombophilia in patients, both of which may contribute to the development of NAION. It is uncertain whether the association of NAION and COVID-19 was causal or coincidental but the purpose of this case report is to argue that there is biological plausibility and to help shed light on potential ophthalmologic complications of COVID-19.
非动脉炎性缺血性视神经病变（NAION）被认为是由视神经血流丧失引起的，进而导致急性、单侧且无痛性视力丧失，影响老年血管病变患者。我们报告一例43岁西班牙裔男性，在2019冠状病毒病（COVID-19）感染背景下出现典型的NAION表现。有充分文献记载，严重急性呼吸综合征冠状病毒2（SARS-CoV-2）可导致患者低氧血症和血栓形成倾向，这两者都可能促使NAION的发生。NAION与COVID-19之间的关联是因果关系还是巧合尚不确定，但本病例报告的目的是论证其存在生物学合理性，并有助于阐明COVID-
