Supplementary Material for: Early Manifestation of Benign Paroxysmal Positional Vertigo: A Case Report

we report a case of a 4.5-month-old infant with paroxysmal horizontal nystagmus, provoked by positioning. The clinical findings and successful resolution with repositioning manoeuvres indicate a diagnosis of right lateral semicircular canal lithiasis. This case report contributes to the existing literature by describing BPPV in the youngest age group, as no patients under 5 years have been previously reported. In order to document the case we also present a semi-automatic video analysis pipeline for analyzing abnormal eye movements in a home setting.
