Eyelid myoclonia with absences (EMA) in two monovular twins.

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).
