AIM: The current world has changed in all shapes since the emergence of the novel coronavirus (nCoV-2) also known as COVID-19. Among the extra-pulmonary manifestations of nCoV-2, ophthalmic symptoms have less been systematically studied. The so far existing body of evidence indicates that nCoV-2 has the potential to affect both anterior and posterior chambers of the eye. Albeit, the exact mechanisms which underlie ophthalmic manifestations of nCoV-2 are yet to be elucidated. METHODS: The present brief review is an attempt to put together and highlight the significant yet limited number of studies which have spotlighted ophthalmic issues in nCoV-2 patients using a systematic literature search strategy. RESULTS: All case series or reports (including both published and preprint articles) which described ocular manifestations of patients with COVID-19 and/or documented testing of SARS-COV-2 in ocular secretions via various sampling or detection methods were sought to be included. CONCLUSION: The ophthalmic presentations in SARS-COV-2 are often found to be salient. Raising awareness in this respect may help defining evidencebased protective measures in today’s practice of ophthalmology and allied disciplines.
