COVID-19 provoked internuclear ophthalmoplegia in a child with arrested hydrocephalus.

Internuclear ophthalmoplegia (INO) is a neuro-ophthalmic disorder caused by damage in the medial longitudinal fasciculus between the third and sixth cranial nerve nuclei. We present a 4-year-old female diagnosed with INO triggered by coronavirus disease 2019 (COVID-19) infection. The patient had history of neonatal meningitis with hydrocephalus without history of surgical intervention. To the best of our knowledge, this is the first case with combined COVID-19 and chronic hydrocephalus as an etiology for INO in a child. COVID-19 may trigger neurological manifestations as INO in susceptible cases.
