Article Abstract
We report 2 patients who had eyelid retraction and eyelid lag with minimal impairment of vertical gaze.In both patients,magnetic resonance imaging demonstrated a circumscribed unilateral lesion immediately rostral and dorsal to the red nucleus involving the lateral periaqueductal gray area. Our clinical and radiological findings support the existence of a premotor eyelid control center in the region of the nucleus of the posterior commissure.
