RESUMEN
This study aims to report a case of neuro-ophthalmic manifestation in a coronavirus disease 2019 (COVID-19) patient and a literature review of neuro-ophthalmological manifestation in COVID-19 patients. A 57-year-old male presented with headache, giddiness, and sudden onset of diplopia over two days after having a flu-like illness. Clinical examination revealed bilateral bizarre extraocular movement with right lower motor neuron facial nerve palsy. A polymerase chain reaction test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was positive. Computed tomography (CT) and contrast-enhanced CT of the brain and CT venography were unremarkable. Magnetic resonance imaging (MRI) of the brain, magnetic resonance angiography of the circle of Willis, and MRI of the internal auditory meatus revealed a subacute pontine infarction with no leptomeningeal or cranial nerve enhancement and a normal circle of Willis. The patient received a course of oral prednisolone and clinical symptoms improved gradually. Articles published between December 2019 and June 2022 were included. A total of 23 cases, with 14 male and nine female patients, were summarized. The mean age at presentation was 46.95 years (range = 9-71 years), with the most affected age group ranging from 31 to 70 years (17 of 23 cases, 73.91%). Neuro-ophthalmological symptoms and signs can be isolated or associated with neurological syndromes. The manifestations include optic neuritis, isolated or multiple cranial nerve palsies, acute vision loss, Miller Fisher syndrome, myasthenia gravis, acute disseminated encephalomyelitis, Guillain-Barré syndrome, internuclear ophthalmoplegia, and cerebrovascular events. Diagnosing neuro-ophthalmic complications secondary to SARS-CoV-2 infection is challenging, as there are no pathognomonic symptoms to detect the disease. High clinical suspicion aids in early diagnosis and initiation of treatment may help in relieving the symptoms.
RESUMEN
Corona virus disease 2019 (COVID-19) has been documented to have a spectrum of neuro-ophthalmic manifestations. However, bilateral non-arteritic anterior ischemic optic neuropathy (NAION) post-COVID-19 has not been reported in the literature. We studied the case of a 45-year-old male who presented to our outpatient department (OPD) with bilateral blurring of vision following an episode of COVID-19, 1 month back. Examination and investigations were conclusive of a bilateral NAION. The patient was given a trial of oral steroids. However, the vision loss could not be recovered. Thus, through this case report, we would like to highlight the importance of a close follow-up of patients following COVID-19 infection to detect any sequelae.
