The effects of lesions of the dorsal 'oculomotor' cerebellar vermis on binocular oculomotor functions in three monkeys were examined. Prominent findings included (1) a convergence bias during monocular fixation, i.e., an 'esodeviation' in the absence of disparity cues, (2) a loss of comitancy, i.e., alignment varies more with orbital position, (3) abnormal saccade yoking producing saccade disconjugacy, and (4) defects in prism-induced phoria adaptation. There was also a suggestion of a disturbance in the dynamic properties of disparity-induced vergence. These findings point to a role for the 'oculomotor' vermis in binocular aspects of the control of eye movements.
研究了三只猴子背侧“动眼神经”小脑蚓部损伤对双眼动眼功能的影响。主要发现包括：（1）单眼注视时存在集合偏差，即在无视差线索时出现“内斜视”；（2）一致性丧失，即眼球位置随眼眶位置变化更大；（3）异常的扫视联带运动导致扫视非共轭；（4）棱镜诱导性隐斜适应缺陷。此外，还有证据表明视差诱导性辐辏的动态特性受到干扰。这些发现表明“动眼神经”蚓部在眼球运动控制的双眼方面发挥作用。
