These videos address each individual class of eye movement, and the proper technique to evaluate each. The videos themselves are narrated with regard to how to perform the maneuvers. VOR (slow and fast): Slow VOR: Since smooth pursuit and VOR systems are both active, if eye movements are choppy with this maneuver this implies deficits in both pursuit and the vestibular system as in CANVAS; Fast (HIT): Since smooth pursuit fails at high frequencies and high speeds, the VOR is isolated during the HIT even with the lights on; if the eyes initially move with the head during the HIT and then make a “catch-up” saccade back to the examiner’s nose (in the opposite direction to the head movement), this is a + HIT toward the side of the rapid head movement and generally indicates a peripheral localization This video is part of the NOVEL Exam Collection in NOVEL, the Neuro-Ophthalmology Virtual Education Library.
