Neuro-Ophthalmic Complications of COVID-19 Infection and Vaccination.

The COVID-19 pandemic has led to the identification of new disease phenotypes associated with infection by the SARS-CoV-2 virus. This includes multiple neuro-ophthalmological sequelae, which have been associated with COVID-19 infection and administration of COVID-19 vaccines. Some of these associations have a plausible pathophysiological link to the infection or vaccination but true causation has yet to be established. We review the literature for associations reported between COVID-19 infection or vaccination and neuro-ophthalmic sequelae and review the potential pathophysiological processes that may underlie these associations.
