Notes

  1. 1.

    This sign is commonly present in MG patients with unilateral ptosis. The patient is asked to look down, thereby inhibiting the levator muscles. After about 15 seconds, the patient looks up to the examiner’s nose or an object at eye level, and if the sign is present, the previously ptotic lid overshoots and is transiently higher than the other lid. The retracted lid then slowly drops to its previous ptotic position.
