The horizontal optokinetic nystagmus (NOC) has been studied during 5,000 otoneurological investigations. In 16.25% of all our cases, the NOC was found to be either weakened in both directions, or only in one direction. There has been no constant relationship between intensity of the spontaneous nystagmus and NOC asymmetry in case of peripheral vestibular lesion. NOC asymmetry seems to be a reliable sign of the evolution of a lesion. Cases without peripheral hypofunction have been divided into three groups: ocular disturbances, brain stem lesions and hemispherical lesions. In these cases the value of the localization of the asymmetry in NOC and nystagmus induced by vestibular tests has been studied. In hemisperical lesions, when asymmetry affected exclusively the NOC, the direction of the weakened NOC was always towards the healthy side. When asymmetry affected not only NOC but even nystagmus induced by vestibular stimulations, this weakened side of the nystagmus was less significant.
在5000例耳神经学检查中对水平视动性眼震（NOC）进行了研究。在我们所有的病例中，16.25%的患者被发现NOC在两个方向上均减弱，或仅在一个方向上减弱。在周围性前庭病变的情况下，自发性眼震的强度与NOC不对称之间不存在恒定关系。NOC不对称似乎是病变进展的可靠标志。无周围性功能减退的病例被分为三组：眼部障碍、脑干病变和半球病变。在这些病例中，研究了NOC不对称和前庭试验诱发的眼震的定位价值。在半球病变中，当不对称仅影响NOC时，减弱的NOC方向总是朝向健康侧。当不对称不仅影响NOC，甚至影响前庭刺激诱发的眼震时，眼震减弱的一侧则不太明显。
