The visual-ocular and vestibulo-ocular reflexes in vestibular migraine.

Abstract

Vestibular migraine is a disease from the border of neurology and otoneurology. The diagnosis depends on patient history. There are no valuable laboratory or imaging tests, therefore the examination of visual-ocular and vestibulo-ocular reflexes is very useful in this group of patients. The material was collected from patients diagnosed due to dizziness at the Department of Otolaryngology and Oncology with the Subdepartment of Audiology and Phoniatrics, CM UMK in Bydgoszcz in 2019-2021. We considered patients with vestibular migraine and analyzed videonystagmographic tests in this study. The most common VNG abnormalities in patients suffering from vestibular migraine were an increased labyrinthine response, increased time constant of the rotational response and abnormal optokinetic response. There was not a single case of canal paresis in the group of patients with vestibular migraine.
