[Photic epilepsy]

Fourteen cases of patients with photoconvulsive response during intermitent luminous stimulation (eleven women and three men) are reviewed. The frequency of the photoconvulsive response was higher between 10 and 20 years of age (eleven cases). Most of the patients (twelve) presented some form of epilepsy and only two had psychomotor retardation without epilepsy. Comment is made on differences published by other authors and possible explanations of such differences are proposed.
