Cranial computed tomography demonstrated hemorrhage in the cerebellar vermis and its vicinity. These symptoms gradually resolved within three wee...

متن کاملConsiderations on the mechanisms of alternating skew deviation in patients with cerebellar lesions.
Alternating skew deviation, in which the side of the higher eye changes depending upon whether gaze is directed to the left or the right, is a frequent sign in patients with posterior fossa lesions, including those restricted to the cerebellum. Here we propose a mechanism for alternating skews related to the otolith-ocular responses to fore and aft pitch of the head in lateral-eyed animals. In ...
متن کاملCerebellar skew deviation and the torsional vestibuloocular reflex.
BACKGROUND Skew deviation is typically caused by brainstem damage, and has not been identified with focal cerebellar lesions. This vertical strabismus has been attributed to asymmetric disruption of vestibuloocular reflex (VOR) projections from otolithic receptors of the utricle to ocular motoneurons, but asymmetry of the utriculo-ocular counter-roll reflex has not been detected. METHODS Lesi...
