Catch-Up Saccades in Vestibulo-Ocular Reflex Deficit: Contribution of Visual Information?
Visual information significantly impacts catch-up saccade latency and the relative number of covert saccades during head impulse testing in vestibular deficit. However, in more than 50% of trials involving a visuo-vestibular mismatch, catch-up saccades remained directed in the compensatory direction relative to head movement, that is, they were visually discordant. Therefore, contrary to previously published proposals, visual information does not appear to be the primary component of the multisensory inputs required for the production of catch-up covert saccades in vestibular deficit. Finally, we discuss a new nomenclature of catch-up saccades in case of vestibular deficit introducing the terms of open and closed loop saccades.
