Cerebral Ptosis

Abstract

Ptosis, unilateral or bilateral, partial or complete, occurring in cases of cerebral ischemic or hemorrhagic stroke, trauma or tumor without involvement of brainstem or oculo-sympathetic mechanism can be termed as cerebral ptosis. Such eyelid dysfunction can occur with hemispheric involvement of either side. It is associated with higher frequency of gaze preference to side of lesion as well as upgaze limitation compared to patients without cerebral ptosis. Here, we present our observations in four such patients with stroke and discuss its evaluation and implications with a brief review of literature.
