A case that combines cerebral eyelid ptosis and blepharospasm secondary to cerebral hemisphere infarction is shown. EMG recording from the facial and eyelid muscles revealed lack of the levator palpebrae superioris, orbicularis oculi and corrugator muscles activity. Any voluntary opening attempt lead to a simultaneous contraction of the three muscles. Blink reflex responses were normal although showed facilitation features on the right side and mild inhibition characteristics from the left side. Median nerve SEP revealed a loss of precentral components (P22-N30) as well as a delay and amplitude decrease of N20. Transcranial magnetic stimulation disclosed a complete lesion of corticospinal pathway for right upper limb. In this case, a right hemisphere lesion caused an unusual eyelid motor abnormality: cerebral eyelid ptosis and blepharospasm induced by the voluntary eyelid opening.
