“…It is unclear whether these vestibular effects are of central or peripheral origin, or whether this varies across individuals. However, in view of the present findings, brainstem vestibular nuclei, cortical regions of visual-vestibular overlap (47) and/or peripheral vestibular structures seem more likely sites of abnormality than the vestibulo-cerebellum, although the latter cannot be ruled out.…”

Ocular Motor Measures in Migraine with and Without Aura

et al. 2006

The purpose of this study was to examine basic ocular motor function in individuals with migraine. We used an infrared eye-tracking system to measure horizontal smooth pursuit to a sinusoidal target, saccades to horizontal target displacements of 5-20 degrees , and the stability of fixation in 19 migraine without aura (MoA), 19 migraine with aura (MA) and 19 headache-free control (C) subjects. Eye movement measurements were made at two target displacement rates and against both homogeneous grey and patterned backgrounds. We found no statistically significant differences between migraine and control subjects in any of the eye movement parameters measured, but did find highly significant effects of both target speed and background pattern in all groups. Our results do not provide support for subclinical cerebellar impairment in migraineurs, and do provide evidence that previously described visual abnormalities in migraine are not artefacts of abnormal fixation or eye movements.
