Acute Severe Bilateral Visual Loss as Presenting Symptom of COVID-19 Infection

 Coronavirus disease 2019 (COVID-19) has emerged as a pandemic and is accompanied by extraordinary morbidity and mortality. Critically ill COVID-19 patients have frequent thrombotic problems and laboratory evidence of hypercoagulability. The spectrum of presentations and complications of COVID-19 is still evolving. We describe a patient with unusual visual symptoms as the presenting signs of COVID-19.

 In this case report, we describe a patient who presented with acute severe bilateral visual loss and headache. On neurological examination, cranial nerves were normal. There was no motor and sensorial abnormality. While the patient was in the emergency room, he was tested positive for COVID-19 via nasopharyngeal swab polymerase chain reaction (PCR) as part of COVID-19 surveillance. An unenhanced brain CT scan showed infarction in the occipital cortex bilaterally due to ischemic stroke involving the Posterior Cerebral Artery (PCA). A few hours later, oxygen saturation was 42%, and a sudden decline of consciousness was observed, progressing to coma. The neurosurgery intervention failed to change the patient's status, and he was pronounced dead in the next few hours.

 This case illuminates a wide range of COVID-19-related symptomatology and highlights the need for clinicians to be aware of different clinical appearances associated with this infection.
