INTRODUCTION: Although intermittent photic stimulation (IPS) is a widespread and routinely used procedure in EEG laboratories, only relatively recently has a standardization of the IPS method been proposed. IPS is an activation method used during EEG procedure that may trigger either physiological or potentially pathological responses. Historically, the term photosensitivity is referred to abnormal responses to stroboscopic light during EEG. OBJECTIVE: The purpose of this publication was to provide an overview of the diagnostic aspects of IPS procedure, based on data presented at Consensus Meetings held in Heemstede, the Netherlands, in 1996, with the purpose of facilitating the detection of photosensitive patients.
