Different time course of compensation of subjective visual vertical and ocular torsion after acute unilateral vestibular lesion

Abstract: Purpose Time course of the recovery of otolithic dis-function caused by superior vestibular neuritis has been examined in fifteen patients. Methods The subjective visual vertical (SVV) and the ocular cyclotorsion (OT) have been measured four times after the acute episode up to 1 year Results In most of the patients the SVV tilt returned to control values within few months (3-6 months) after the acute episode, while OT remained out of normal range in almost all patients a year later. Conclusion The abnormal OT … Show more

“…The involvement of the vestibular system in the perception of the vertical has also been revealed by clinical tests (for review Brandt and Dieterich, 1994 ). When the injury occurs at the peripheral level, the subjective perception of verticality is deflected ipsilesionally (Friedmann, 1970 ; Böhmer and Mast, 1999 ; Vibert and Häusler, 2000 ; Lopez et al, 2007 ; Faralli et al, 2021 ).…”

“…The OTR test includes head tilt (HT), skew deviation (SD), ocular torsion (OT), and subjective visual vertical (SVV) tilt. In previous studies, the rates of abnormal HT, SD, abnormal OT, and abnormal SVV in patients with acute peripheral vestibular syndrome were 4-20%, 14-29%, 19-82%, and 50.6-94% (7)(8)(9)(10)(11), respectively. The rates of abnormal HT, SD, abnormal OT, and abnormal SVV in ACVV patients were 3-38%, 29-31%, 57-83%, and 74.1-94% (12)(13)(14), respectively.…”

“…16 However, the deviation of the subjective visual vertical from the vertical line is a clinical sign of static vestibular disfunction. 17 Ipsilesional deviation of the subjective visual vertical indicates damage within the peripheral vestibular system, 18 and contralateral deviation can be a sign of damage to the central vestibular system. 19 Our hypothesis is that studying the two functions in a sample of patients suffering from unilateral vestibular neuritis in the acute phase (less than 72 hours from onset) and some days after the onset of symptoms using ocular vestibularevoked myogenic potentials and subjective visual vertical could give different results.…”
