Prévost sign (eyes)

The Prévost sign refers to deviation of the eyes away from the hemiparesis in acute cortical hemiparetic stroke. Therefore, the eyes are deviated towards the involved hemisphere and may be exaggerated when the head is turned in the same direction. It is most pronounced with non-dominant hemisphere (thus right) lesions. 

History and etymology

It is named after Jean Louis Prévost, Swiss physician (1838-1927).
