There is an increasing body of knowledge regarding how COVID-19 may be associated with ocular disease of varying severity and duration. This article discusses the literature on the ocular manifestations associated with COVID-19, including appraisal of the current evidence, suggested mechanisms of action, associated comorbidities and risk factors, timing from initial infection to diagnosis and clinical red flags. The current literature primarily comprises case reports and case series which inevitably lack control groups and evidence to support causality. However, these early data have prompted the development of larger population-based and laboratory studies that are emerging. As new data become available, a better appraisal of the true effects of COVID-19 on the eye will be possible.

COVID-19 的眼部表现


关于 COVID-19 与不同严重程度和持续时间的眼部疾病之间的关系，人们的了解越来越多。本文讨论了有关 COVID-19 相关眼部表现的文献，包括对当前证据的评估、建议的作用机制、相关合并症和危险因素、从初次感染到诊断的时间以及临床危险信号。目前的文献主要包括病例报告和病例系列，不可避免地缺乏对照组和支持因果关系的证据。然而，这些早期数据促进了正在出现的更大规模的基于人群的实验室研究的发展。随着新数据的出现，将有可能更好地评估 COVID-19 对眼睛的真实影响。
