本文报告1980至1986年华西医大附一院神经内科脑电图室1015例儿童癫痫患儿的光活化反应。共出现光搐搦反应89例,占癫痫患儿的8.77%;光敏感癫痫4例,占癫痫患儿的0.39%。结合文献讨论认为光活化反应中,光肌阵挛反应临床意义不大,光搐搦反应和光敏感癫痫都支持癫痫的诊断,且异常脑电还具有定位价值。据本组资料,PCR 的最有效频率为8～25Hz,PSE 的最有效频率为12～21Hz。 This article reports the photoactivation of 1015 children with epilepsy in the EEG Room of the First Affiliated Hospital of Huaxi University from 1980 to 1986. A total of 89 cases of seizures reaction, accounting for 8.77% of children with epilepsy; light-sensitive epilepsy in 4 cases, accounting for 0.39% of children with epilepsy. According to the literature discussion, it is considered that the clinical significance of myoclonus in photoactivation is not significant, and the seizures and photic epilepsy support the diagnosis of epilepsy, and the abnormal EEG also has the value of localization. According to this group of information, the most effective PCR frequency of 8 ~ 25Hz, PSE, the most effective frequency of 12 ~ 21Hz.
