Independent Measures of Utricular Function: Ocular Vestibular Evoked Myogenic Potentials Do Not Correlate With Subjective Visual Vertical or Fundus Photographic Binocular Cyclorotation

Ocular vestibular evoked myogenic potentials (oVEMPs), subjective visual vertical (SVV), and fundus photographically measured binocular cyclorotation (BCR) are diagnostic tests to assess utricular function in patients with vertigo or dizziness. In 138 chronic dizziness, we asked whether the asymmetry ratio of oVEMP (normal, right side pathological, left pathological) could predict SVV deviation rightward deviation, leftward deviation) BCR right, left). There was no correlation between BCR, while correlated highly. Although both measure aspects function, our findings demonstrate that not redundant may reflect different pathologies. The role photographic be relegated only confirm unclear results workup.
