The authors studied the vertical saccadic movements of 12 patients with vertical paretic strabismus (< 6 degrees) by Scott's method, comparing the saccade of the paretic muscle with that of its antagonist. The results showed that the former was reduced in amplitude by 15%-50%, averaging 31.5%, and improved to 0%-25%, averaging 8.1%, after operations. The authors proposed that a difference of saccadic amplitude over 15% between a muscle and its antagonist indicated presence of muscle paresis. Besides, the methods of assessing saccadic movements were discussed.
作者采用斯科特法研究了12例垂直性麻痹性斜视（<6度）患者的垂直扫视运动，将麻痹肌的扫视与拮抗肌的扫视进行比较。结果显示，前者的幅度降低了15%-50%，平均为31.5%，术后改善至0%-25%，平均为8.1%。作者提出，肌肉与其拮抗肌之间的扫视幅度差异超过15%表明存在肌肉麻痹。此外，还讨论了评估扫视运动的方法。
