EMA (eyelid myoclonia with absences) consists of brief seizures triggered by eyelid closure and characterized by absence and palpebral myoclonia. The EEG shows brief discharges with 3 per second spike and wave complexes. The present report describes the cases of 2 monovular twins who started to have this form of epilepsy at the age of 4 1/2 years. Their seizures, after 2 years of follow-up, are greatly reduced with combined therapy of valproic acid and benzodiazepines (Clobazam).
