严重急性呼吸系统综合征冠状病毒2型(SARS-CoV-2)于二零一九年十二月首次出现,并迅速蔓延,导致二零一九年冠状病毒病(COVID-19)大流行。最近的单细胞RNA-Seq分析表明,在人类角膜、角膜缘和结膜浅表上皮中存在SARS-CoV-2进入因子,这表明人类眼表可能是SARS-CoV-2的额外入口和感染中心。在这篇文章中,我们回顾了COVID-19的眼部临床表现和眼表特征,这些特征可能强调了整体低眼部SARS-CoV-2感染。我们批判性地评估了在非人灵长类动物、离体器官培养眼模型、干细胞衍生的眼类器官中进行的研究,以及在人眼表上皮不同部位观察到的感染效率差异。最后,我们强调了需要进行的额外工作,以了解眼表对SARS-CoV-2感染的免疫反应,这可以转化为可应用于其他器官系统的预防性治疗。示意图显示SARS-CoV-2通过眼表上皮感染(左手侧图)或全身途径(右手侧图)进入眼睛的可能性。
Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) first emerged in December 2019 and spread quickly causing the coronavirus disease 2019 (COVID‐19) pandemic. Recent single cell RNA‐Seq analyses have shown the presence of SARS‐CoV‐2 entry factors in the human corneal, limbal, and conjunctival superficial epithelium, leading to suggestions that the human ocular surface may serve as an additional entry gateway and infection hub for SARS‐CoV‐2. In this article, we review the ocular clinical presentations of COVID‐19 and the features of the ocular surface that may underline the overall low ocular SARS‐CoV‐2 infection. We critically evaluate the studies performed in nonhuman primates, ex vivo organ culture ocular models, stem cell derived eye organoids and the differences in infection efficiency observed in different parts of human ocular surface epithelium. Finally, we highlight the additional work that needs to be carried out to understand the immune response of the ocular surface to SARS‐CoV‐2 infection, which can be translated into prophylactic treatments that may be applied to other organ systems.
