A male infant with myoclonic astatic epilepsy showed myoclonic seizures of the eyelids by closing of the eyes. There was no photosensitivity in EEG with flash‐stimulation and he could induce seizures even in total darkness. The latency between a lid closure and onset of seizure discharges on EEG was relatively long (0.3‐0.5 second). Epileptic seizures in this patient may be induced via a brainstem reticular formation, and elevated Bell's position seems to be the necessary stimulus to produce seizures.
