Title: Otoconial loss a new important diagnosis - explanation for residual dizziness and chronic imbalance

Abstract

Subjective Visual Vertical and Horizontal (SVV/SVH), Binocular Cyclorotation (BCR) measured by fundus-photography and ocular Vestibular Evoked Potentials (oVEMPs) are available as simple tests to measure utricular function in ambulant settings. Often, these tests reveal contradictory results. There is no proven disease or lesion explaining these differences, but two hypotheses are around a) isolated hypofunction of utricular type 2 hair cells or otoconial loss. The arguments for both hypotheses will be discussed. It will be explained why otoconial loss seems the more reasonable explanation in most cases.
