Description |
Following an acute lesion of one cerebral hemisphere, the eyes usually deviate conjugately toward the side of the lesion (Prevosts or Vulpians sign). Gaze deviations are more common after large strokes involving predominantly the right postrolandic cortex. Visual hemineglect often accompanies such gaze deviations. Gaze deviation that occurs after a stroke usually resolves within a few days to a week; if gaze deviation persists, there may be a previous lesion in the contralateral frontal lobe. In general, for comparably sized lesions, ocular motor defectsboth pursuit and saccadesare more profound when the lesion is in the nondominant hemisphere. |
