Eye closure epilepsy, report of an uncomplicated case.

A case of a 5 year-old male, who has uncomplicated eye closure epilepsy, is reported. Always, at the lowering of the eyelids, he presented diffuse discharges of polyspikes, accompanied by myoclonic fits. There was not loss of awareness, and this phenomenon happened both in darkness and with passive eye closure. The neurological examination was negative. Previously reported cases, all already epileptic, showed a polymorphism of triggering mechanisms such as motor or sensory processes or both together. The lowering of the eyelids is complex, and a great variety of factors must be involved in the triggering of this kind of epilepsy.
