title: Transient eyelid retraction in myasthenia gravis.
abstract: Three patients with myasthenia gravis had transient retraction of the upper eyelids which usually followed prolonged upgaze and which persisted for many seconds. This could result from post-tetanic facilitation, myotonia, or a transient contracture. Retraction of this type is to be distinguished from both the long-standing unilateral retraction associated with ptosis of the contralateral eyelid and the fleeting lid twitch sign.
