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 patients with chronic vertigo or dizziness, we asked whether the asymmetry ratio of oVEMP (normal, right side pathological, left side pathological) could predict the SVV deviation (normal, rightward deviation, leftward deviation) or BCR (normal, cyclorotation to the right, cyclorotation to the left). There was no correlation between oVEMP and SVV and between oVEMP and BCR, while SVV and BCR correlated highly. Although both oVEMP and SVV measure aspects of utricular function, our findings demonstrate that oVEMP and SVV are not redundant and may reflect different utricular pathologies. The role of fundus photographic BCR may be relegated to only confirm unclear SVV results in vestibular diagnostic workup.
眼前庭诱发肌源性电位（oVEMP）、主观视觉垂直（SVV）以及眼底照相测量的双眼旋转（BCR）是评估眩晕或头晕患者椭圆囊功能的诊断测试。在138例慢性眩晕或头晕患者中，我们探讨了oVEMP的不对称率（正常、右侧病变、左侧病变）是否能够预测SVV偏差（正常、向右偏差、向左偏差）或BCR（正常、向右旋转、向左旋转）。oVEMP与SVV之间以及oVEMP与BCR之间均无相关性，而SVV与BCR高度相关。尽管oVEMP和SVV均测量椭圆囊功能的某些方面，但我们的研究结果表明，oVEMP和SVV并非冗余，可能反映不同的椭圆囊病变。眼底照相BCR的作用可能仅在于在眩晕诊断检查中确认不清楚的SVV结果。
