Normal Saccades

"Stationary targets, such as the examiner's fingers, are held in front of the subject. The subject is instructed to look back and forth between the targets on verbal commands. The eye movements are conjugate, rapid, and accurate. The observer looks for any differences in speeds of the eye movements between the eyes and different directions. He evaluates the accuracy and the ability to quickly initia te saccades on command. Slight overshooting of saccades during refixations to center gaze targets are often present in normal subjects. Small amplitude secondary saccades are made to correct the slight inaccuracy. Slight undershooting during large amplitude refixations to eccentric targets is also normally found. "
