Neuro-Ophthalmic Manifestations of Covid-19 Infection and Vaccination

We describe cases of visual snow syndrome, optic neuritis, cranial nerve palsies and ocular myasthenia gravis newly diagnosed in the setting of a recent coronavirus disease 2019 (COVID-19) infection or vaccination with Pfizer-BioNTech. We also report the ocular exam findings, workup and treatment of the eight patients with these neuro-ophthalmic manifestations. Recognition of these conditions as possible early manifestation of the infection would result in decreased viral transmission and better diagnosis. Further investigation is recommended to depict the pathogenesis of COVID-19 infection or vaccination and these neuro-ophthalmic manifestations.Funding Information: None.Declaration of Interests: The authors have no financial interest in the subject matter of this manuscript.Ethics Approval Statement: All patients consented to sharing their exam findings with the scientific community.
