Video Head Impulse Test

The VHIT enables to test all 6 semi-circular canals at high frequency as well as the saccades strategies (overt and covert). VOR Suppression (VORS) tests identify the presence or absence of saccadic eye movement in order to simultaneously test for the co-existence of vestibular and cerebellar pathology and thus diagnose vestibulo-cerebellar disorders.

• Quick test : 10 minutes to independently test the 6 canals and detect saccades (overt and covert)
• Nine axis motion sensor accurately measures the head movement allowing for simultaneous comparison of head and eye movement
• High frame rate camera ( 200 fps) allows precise tracking of eye movements during head impulse
• Lightweight goggle design to reduce slippage (Maximum weight 150 grams)
• Built-in lasers that provide stimulus for calibration and VORS testing
• The unique design of the goggles presents the suppression stimulus from the goggles in order to assess VORS
• Fully integrated and computerized with real time recording of all parameters
• Videos of the eye movement can be viewed after the test
• Detailed, customized reports automatically created in pdf format
