Characteristics of vestibular corrective saccades in patients with slow visual saccades, vestibular disorders and controls: A descriptive analysis.

摘要: Objective Our aim was to determine whether overt catch up saccades (OS) provoked by vestibular stimuli, as observed in the video head impulse test (vHIT), have comparable metrics visually triggered horizontal (VS), indicating a common saccadic brainstem generator. Methods Three groups of patients were studied: with neurological disorders causing slow (group 1, n = 12), peripheral lesions 2, 43), and normal controls 3, 24). All underwent vHIT Videooculographic testing. OS velocity, acceleration, amplitude duration VS velocity this group compared between groups. Results There significant reduction guided expected from patient selection constraints study. Group 1 also exhibited which longer reduced acceleration when subjects without slowing visual targets (Group 2 3). There positive correlations both saccade (2 3) not (1). Conclusions The measured are similar saccades. This supports hypothesis that associated stimuli share circuitry metrics.
