Horizontal smooth pursuit eye movements were quantitatively evaluated in forty patients with various neurological diseases (chronic alcoholism, acusticusneurinom and multiple sclerosis) as well as in twenty-four healthy subjects. Different frequency sinusoidal targets with an amplitude of 20 degrees were used. The quantitative analysis was possible after calculating the pursuit value as the difference between the saccadic part and the maximal amplitude of the recorded eye movement. Maximal and minimal P-values of 0.5, 0.7 and 0.9 Hz were chosen in the discriminant analyses. It is suggested that these parameters are very helpful in distinguishing between the groups of patients and the group of subjects.
对40例患有各种神经系统疾病（慢性酒精中毒、听神经瘤和多发性硬化症）的患者以及24名健康受试者进行了水平平滑跟踪眼球运动的定量评估。使用了振幅为20度的不同频率正弦目标。在计算跟踪值（作为记录的眼球运动的扫视部分与最大振幅之间的差值）后，进行定量分析成为可能。在判别分析中，选择了0.5、0.7和0.9赫兹的最大和最小P值。结果表明，这些参数对于区分患者组和受试者组非常有帮助。
