Thirty six patients were studied with a classical photoparoxysmal EEG response to intermittent photic stimulation (IPS). Clinical observations and complaints reported by patients during standardised IPS were recorded and compared with historical data. Twenty seven patients experienced impaired consciousness or showed motor phenomena such as involuntary opening of the eyes or jerking on one or both sides of the body. Twenty five patients had sensations such as pain in the eyes, jerking etc. There existed no relation between the duration of the evoked discharges (0.5-3 seconds) and observed signs or complaints. In 11 instances the clinical features found during IPS were not reported in a history taken from the patient and relatives.
对36例对间歇性光刺激（IPS）有典型光阵发性脑电图反应的患者进行了研究。记录患者在标准化IPS期间报告的临床观察结果和主诉，并与历史数据进行比较。27例患者出现意识障碍或表现出运动现象，如不自主睁眼或身体一侧或双侧抽搐。25例患者有眼部疼痛、抽搐等感觉。诱发放电持续时间（0.5 - 3秒）与观察到的体征或主诉之间没有关系。在11例中，IPS期间发现的临床特征在患者及其亲属的病史中未被报告。
