 In addition to the small pupil in the trupy eyelid consisting of a central hornar syndrome, look over here to the right. He has some nystagmus on right gaze, which isn't very prominent. Now look straight ahead, and we see that on making that rapid refixation move that he has a series of very small hypo-metric saccades. Look over here to the left, more saccades. Now look to your straight ahead, and he overshoots. Look over here, straight ahead, and look over here, straight ahead. Again, overshooting. Now look up here, now look straight ahead, and you see that he makes a little hook over toward the right as he looks down. This is called lateral pulsion. Look up here, look right straight up. Now look straight ahead. Now look down here, and look at the camera. And again, he looks over, he hooks over to the right. Now close your eyes loosely, open, and we see that with his eyes closed, his eyes laterally deviate to the right. Now close tightly, and when he scrunches his eyes closed, now open, a much more prominent lateral pulsive move is made.
