Over the last decade, ocular vestibular evoked myogenic potentials (oVEMPs) have evolved as a new clinical test for dynamic otolith (predominantly utricular) function. The aim of this review is to give an update on the neurophysiological foundations of oVEMPs and their implications for recording and interpreting oVEMP responses in clinical practice.
Different lines of anatomical, neurophysiological, and clinical evidence support the notion that oVEMPs measure predominantly contralateral utricular function, while cervical cVEMPs are an indicator of ipsilateral saccular function. Bone-conducted vibration (BCV) in the midline of the forehead at the hairline (Fz) or unilateral air-conducted sound (ACS) are commonly used as stimuli for oVEMPs. It is recommended to apply short stimuli with short rise times for obtaining optimal oVEMP responses. Finally, this review summarizes the clinical application and interpretation of oVEMPs, particularly for vestibular neuritis, Ménière's disease, superior canal dehiscence and "challenging" patients.
在过去十年中，眼震前庭诱发肌源性电位（oVEMP）已发展成为一种用于评估动态耳石（主要是椭圆囊）功能的新临床测试方法。本综述的目的是更新oVEMP的神经生理学基础及其在临床实践中对oVEMP反应记录和解读的意义。
不同的解剖学、神经生理学和临床证据支持这样一种观点，即oVEMP主要测量对侧椭圆囊功能，而颈肌前庭诱发肌源性电位（cVEMP）则是同侧球囊功能的指标。在前额发际线中线（Fz）处进行骨传导振动（BCV）或单侧气导声音（ACS）通常用作oVEMP的刺激。建议应用上升时间短的短刺激以获得最佳的oVEMP反应。最后，本综述总结了oVEMP的临床应用和解读，特别是在前庭神经炎、梅尼埃病、半规管裂和“疑难”患者中的应用。
