Electro-oculograms for monitoring eye movements and eye positions were performed in patients having a prolonged episode of acute peripheral vestibulopathy. During the course of such illness counterdrifting eye movements have been observed. Counterdrifting is defined as slow eye movements which develop in the direction opposite to the primary drift (i.e. the slow phase of spontaneous nystagmus), that occur when lateral gaze is attempted in the dark at eye positions on the side ipsilateral to the vestibulopathy. Counterdrifting appears always to be accompanied or followed by some recovery of labyrinthine function on the side of vestibular failure, and in 2 patients it was associated with so-called recovery nystagmus. It has not been observed after vestibular neurectomy. The hypothesis is put forward that counterdrifting could be an oculomotor phenomenon--centripetal drifting--similar to that underlying Alexander's modification of acute vestibular spontaneous nystagmus.
对患有急性外周前庭病长期发作的患者进行了用于监测眼球运动和眼位的眼电图检查。在这类疾病的病程中观察到了反向漂移的眼球运动。反向漂移被定义为在黑暗中试图向患侧眼位侧方凝视时，朝着与原发性漂移（即自发性眼球震颤的慢相）相反方向发展的缓慢眼球运动。反向漂移似乎总是伴随着前庭功能衰竭侧迷路功能的某种恢复或随后出现这种恢复，并且在2例患者中它与所谓的恢复性眼球震颤有关。在前庭神经切除术后未观察到这种现象。有人提出这样的假说，即反向漂移可能是一种眼球运动现象——向心性漂移——类似于亚历山大对急性前庭自发性眼球震颤进行改良的基础。
