Internuclear ophthalmoplegia as a presenting feature in a COVID-19-positive patient

Abstract

A 58-year-old man presented with vertical diplopia for 10 days which was sudden in onset. Extraocular movement examination revealed findings suggestive of internuclear ophthalmoplegia. Investigations were suggestive of diabetes mellitus, and reverse transcription-PCR for SARS-CoV-2 was positive. At 3 weeks of follow-up, his diplopia had resolved. Neuro-ophthalmic manifestations in COVID-19 are increasingly being recognised around the world. Ophthalmoplegia due to cranial nerve palsy and cerebrovascular accident in COVID-19 has been reported. We report a case of internuclear ophthalmoplegia in a patient with COVID-19.
