Persistent Cortical Blindness Following Posterior Reversible Encephalopathy Syndrome (PRES) as a Complication of COVID-19 Pneumonia.

ABSTRACT

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic emerged in China in December 2019. Since then, there have been growing reports of coronavirus disease 2019 (COVID-19) cases with neurological involvement. We present a case of a 54-year-old woman who presented with confirmed SARS-CoV-2 pneumonia, complicated by a prolonged intensive care stay and posterior reversible encephalopathy syndrome (PRES). This resulted in persistent cortical blindness (Anton's syndrome). PRES has only rarely been reported in relation to SARS-CoV-2 infection and no patients have developed persistent cortical blindness. We summarise the clinical presentation of the patient and review the current literature.
