HINTS Examination in Acute Vestibular Neuritis : Do Not Look Too Hard for the Skew

Copyright © 2020 by North American Neuro-Ophthalmology Society..

BACKGROUND: An ocular tilt reaction (OTR) is a triad of a skew deviation, head tilt, and ocular counter-roll that can be partial or complete. An OTR can occur anywhere along the utriculo-ocular motor pathways from the labyrinth to the interstitial nucleus of Cajal but is almost always central in origin. In acute vestibular neuritis (AVN), case reports have described patients with an OTR due to AVN, although it is unclear whether this examination finding is common or rare.

METHODS: The vestibular and ocular motor features of 7 patients presenting with AVN are described.

RESULTS: Each of the 7 patients presented with typical features of AVN, including contralesional unidirectional spontaneous nystagmus and an ipsilesional abnormal head impulse test, although each patient also had a complete OTR. None of the patients had vertical diplopia or a skew deviation that was measurable with alternate cover testing (i.e., abnormal "test of skew" according to the Head Impulse, Nystagmus, Test of Skew examination); however, all had a subtle 1 prism diopter hyperphoria that was only measurable with a Maddox rod test.

CONCLUSION: Seven cases of typical AVN with an OTR are presented, and in the authors' experience, the presence of a subtle OTR is a common feature of AVN in these patients.
