'Rotatory nystagmus', in which the visual axis of the eye moves involuntarily in the horizontal and vertical planes describing a closed loop trajectory, was analysed by means of combined video and electro-oculography in a patient with multiple sclerosis having numerous ocular signs of cerebellar disease. The rotations were sporadic, isolated single cycles having stereotyped, crescentiform loop shapes. Each consisted of a combination of a single cycle of vertical ocular flutter, the onset of which was followed 40 to 50 milliseconds later by a single cycle of horizontal ocular flutter. The timing relationship between flutters suggest that the vertical and horizontal systems had become somehow entrained. Rotatory nystagmus is saccadic in nature and arises from a unique timing relationship between vertical and horizontal flutter.
“旋转性眼球震颤”是指眼球视轴在水平和垂直平面上不由自主地移动，描绘出一条闭环轨迹。我们通过视频和眼电图相结合的方法，对一名患有多发性硬化症且有众多小脑疾病眼部体征的患者进行了分析。眼球旋转是间歇性的，孤立的单个周期，呈固定的新月形环路形状。每个周期都由一个垂直性眼球扑动的单周期和一个水平性眼球扑动的单周期组合而成，垂直性眼球扑动开始后40至50毫秒会出现水平性眼球扑动的单周期。扑动之间的时间关系表明，垂直和水平系统在某种程度上已相互关联。旋转性眼球震颤本质上是眼跳性的，由垂直和水平扑动之间独特的时间关系引起。
