Two children manifested EEG discharges which were triggered by blinking and/or eye closure in light and in darkness. The first case demonstrated single focal posterior discharges with eye blinks and repetitive focal posterior sharp wave discharges with eye closures. No photoparoxysmal responses were obtainable. Case 2 manifested generalized epileptic discharges triggered by eye closure which were sometimes associated with clinical seizures. In addition she showed photoconvulsive responses. Since the discharges triggered by eye blink and by eye closure occurred in both bright light and in darkness it is suggested that sensory afferents arising from contraction of the orbicularis oculi muscles may have been the epileptic trigger in Case 1 and could have contributed to the epileptic triggering mechanism in Case 2.
两名儿童表现出脑电图放电，在明处和暗处眨眼和/或闭眼时均可触发。第一例在眨眼时表现为单个局灶性后部放电，闭眼时表现为重复性局灶性后部尖波放电。未获得光阵发性反应。第二例表现为闭眼触发的全身性癫痫放电，有时伴有临床发作。此外，她还表现出光惊厥反应。由于眨眼和闭眼触发的放电在明处和暗处均有发生，提示眼轮匝肌收缩产生的感觉传入可能是第一例的癫痫触发因素，并且可能在第二例的癫痫触发机制中起作用。
