Abstract
We report 2 patients who had eyelid retraction and eyelid lag with min imal impairment of vertical gaze. In both patients, magnetic resonance imaging demonstrated a circumscribed unilateral lesion immediately ro stral and dorsal to the red nucleus involving the lateral periaqueduct al gray area. Our clinical and radiological findings support the exist ence of a premotor eyelid control center in the region of the nucleus of the posterior commissure.
