Optokinetic Nystagmus is a test of smooth pursuit with quick resetting saccades. Use a tape with repeating shapes on it and ask the patient to look at each new object as it appears as you run the tape between your fingers to the right, left, up, and down. The patient will have brief pursuit eye movements in the direction of the tape movement with quick saccades or jerks in the opposite direction. The resetting saccades are easier to observe than the brief pursuit movement.
