Severe deficits of foveal smooth pursuit and optokinetic nystagmus in all directions were electro-oculographically recorded in an 80 year old woman. Magnetic resonance imaging (MRI) showed an infarct involving the postero-inferior part of the vermis (lobules VI to X) and a portion of the left cerebellar hemisphere, with apparent preservation of the flocculus and the brainstem. The role of the vermal lesion in these pursuit eye movement disorders is discussed.
一名80岁女性经眼电图记录显示，其向各个方向的中央凹平滑跟踪和视动性眼球震颤均存在严重缺陷。磁共振成像（MRI）显示梗死灶累及小脑蚓部后下部（小叶VI至X）及左侧小脑半球的一部分，而绒球和脑干明显未受影响。本文讨论了蚓部病变在这些跟踪性眼球运动障碍中的作用。
