vOCR 可以检测耳石眼功能的丧失，而无需指定前庭丧失的一侧。由于 vOCR 是通过简单的头部倾斜操作来测量的，因此它可以与视频头部脉冲测试结合用作床边临床测试。视频眼科描记（VOG）护目镜正在被整合到前庭疾病患者的床边评估中。然而，缺乏评估耳石功能的方法。本研究验证了针对耳石功能丧失的 VOG 测试。使用 VOG 测量 12 名健康对照者、14 名单侧前庭丧失 (UVL) 患者和 6 名静态侧向头部倾斜 30° 的双侧前庭丧失 (BVL) 患者的眼部反滚 (vOCR)。结果与前庭肌源性诱发电位（VEMP）进行了比较，这是一种广泛使用的耳石功能实验室测试。健康对照的平均 vOCR (4.6°) 与 UVL (2.7°) 和 BVL (1.6°) 患者显着不同 (p < 0.0001)。 vOCR 和 VEMP 测量值在受试者之间相关，尤其是点击和点击 oVEMP（点击 oVEMP R = 0.45，点击 oVEMP R = 0.51；p < 0.0003）。接收者操作特征 (ROC) 分析表明 vOCR 和 VEMP 检测耳石功能丧失的效果同样好。 vOCR 检测前庭丧失的最佳阈值是 3°。 UVL 患者中前庭丧失侧和健康侧的 vOCR 值没有差异（2.53° vs 2.8°；p = 0.59）。
vOCR can detect loss of otolith-ocular function without specifying the side of vestibular loss. Since vOCR is measured with a simple head tilt maneuver, it can be potentially used as a bedside clinical test in combination with video head impulse test. Video-oculography (VOG) goggles are being integrated into the bedside assessment of patients with vestibular disorders. Lacking, however, is a method to evaluate otolith function. This study validated a VOG test for loss of otolith function. VOG was used to measure ocular counter-roll (vOCR) in 12 healthy controls, 14 patients with unilateral vestibular loss (UVL), and six patients with bilateral vestibular loss (BVL) with a static lateral head tilt of 30°. The results were compared with vestibular evoked myogenic potentials (VEMP), a widely-used laboratory test of otolith function. The average vOCR for healthy controls (4.6°) was significantly different from UVL (2.7°) and BVL (1.6°) patients (p < 0.0001). The vOCR and VEMP measurements were correlated across subjects, especially the click and tap oVEMPs (click oVEMP R = 0.45, tap oVEMP R = 0.51; p < 0.0003). The receiver operator characteristic (ROC) analysis showed that vOCR and VEMPs detected loss of otolith function equally well. The best threshold for vOCR to detect vestibular loss was at 3°. The vOCR values from the side of vestibular loss and the healthy side were not different in UVL patients (2.53° vs 2.8°; p = 0.59).
