[A clinical study of vertical saccadic eye movements].
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.
