Measurement of ocular counterrolling (OCR) is well known as a simple method to evaluate the peripheral vestibular organ, especially the otolith organ. But it has rarely been used because of the difficulty in differentiating between pathologically reduced OCR and the wide physiological variation of this parameter.
In this study, the OCR of 55 patients with unclarified vertigo (n = 20), vestibular neuronitis (n = 15), Menière's disease (n = 10), and benign paroxysmal positional nystagmus (n = 10) were evaluated and compared to a control group (n = 30) with the intention of diagnosing peripheral vestibular dysfunction and establishing a differential diagnosis. The test sequence was carried out with Vesta goggles by Panares and included head tilts of 5 degrees, 15 degrees, and 30 degrees to the left and right.
The results show a significantly reduced OCR in patients suffering from peripheral vestibular disorders when compared to the control group.
There is no specific finding for a specific type of vestibular lesion, but otolith function is affected in several disorders as measured by ocular counterrolling.
眼动反向偏斜（OCR）测量是评估外周前庭器官，尤其是耳石器官的一种简单方法，这已广为人知。但由于难以区分病理性降低的OCR与该参数广泛的生理变异，它很少被使用。
在本研究中，对55例眩晕原因不明（n = 20）、前庭神经炎（n = 15）、梅尼埃病（n = 10）和良性阵发性位置性眼震（n = 10）患者的OCR进行了评估，并与一个对照组（n = 30）进行比较，目的是诊断外周前庭功能障碍并建立鉴别诊断。测试序列由帕纳雷斯使用Vesta护目镜进行，包括向左和向右倾斜5度、15度和30度的头部倾斜。
结果显示，与对照组相比，外周前庭疾病患者的OCR显著降低。
对于特定类型的前庭病变没有特异性发现，但通过眼动反向偏斜测量，耳石功能在几种疾病中受到影响。
