"Double Elevator Palsy"
This name has been given to monocular elevation paresis. It may occur in association with pretectal supranuclear lesions either contralateral or ipsilateral to the paretic eye interrupting efferents from the rostral interstitial nucleus of the medial longitudinal fasciculus to the superior rectus and inferior oblique subnuclei. Bell’s phenomenon may be preserved.
