To critically review data published in the recent past to scrutinize a causal relationship between retinal vascular occlusion and COVID-19.
A comprehensive literature search was performed on Pubmed with the key words retinal vascular occlusion, retinal vein occlusion, retinal artery occlusion, and COVID-19.
A total of 17 case reports were published during this period, and 10 were on retinal vein occlusion and 7 on retinal artery occlusion. Most of the published reports lacked convincing evidences in one or the other aspects, such as insufficient laboratory workup or presence of multiple confounding risk factors.
In this index article, strength of the data is insufficient to establish a definitive cause-and-effect relationship of retinal vascular occlusive disorders with COVID-19. Hence, clinicians can continue to manage these cases according to the standard guidelines until there are more robust evidences to support this association to alter the diagnostic and treatment modalities.
批判性地回顾近期发表的数据，以仔细审查视网膜血管闭塞与 COVID-19 之间的因果关系。
在 Pubmed 上使用关键词“视网膜血管闭塞”、“视网膜静脉阻塞”、“视网膜动脉阻塞”和“COVID-19”进行全面的文献检索。
在此期间共发表了 17 份病例报告，其中 10 份为视网膜静脉阻塞，7 份为视网膜动脉阻塞。大多数已发表的报告在一个或另一个方面缺乏令人信服的证据，例如实验室检查不足或存在多种混杂危险因素。
在本文中，数据的强度不足以确定视网膜血管闭塞性疾病与 COVID-19 之间存在明确的因果关系。因此，临床医生可以根据标准指南继续治疗这些病例，直到有更有力的证据支持这种关联以改变诊断和治疗方式。
