Acute Abducens Nerve Palsy Following the Second Dose of the AstraZeneca COVID-19 Vaccine

The authors report the case of an otherwise healthy 65-year-old man who presented with an acute right abducens nerve palsy 3 days after receiving the second dose of the AstraZeneca coronavirus disease 2019 (COVID-19) vaccine. Abducens nerve palsies typically results from microvascular disease or compressive tumors, although they are known to arise following routine vaccinations. Given the lack of preexisting risk factors, normal computed tomography scan results, and the timing of the symptoms, the abducens nerve palsy was believed to be related to the vaccination. This report highlights the potential neurologic adverse effects associated with COVID-19 vaccines. [ J Pediatr Ophthalmol Strabismus . 2021;58(6):e49–e50.]
