We performed a retrospective analysis of 17 children with photosensitive seizures (PSS) who had been followed for more than 3 years (mean: 9 years). PSS were verified in all patients by simultaneous video-EEG monitoring. The seizures were precipitated by flickering stroboscopes (14 patients) or were induced by patients themselves (3) with head-nodding in front of illumination, blinking at television or close viewing of striped patterns. PSS consisted of myoclonic seizures (eight patients), generalized tonic-clonic convulsions (5), partial seizures (3) or atypical absence (1). According to the International Classification of Epileptic Syndrome, three patients were classified as having severe myoclonic epilepsy in infancy and five as having juvenile myoclonic epilepsy. The remaining nine could not be categorized as any specific epileptic syndrome. Children with age of the onset of epilepsy at 7 years or younger tended to suffer intellectual deficit in addition to intractable seizures.
我们对17例光敏性癫痫（PSS）患儿进行了回顾性分析，这些患儿的随访时间超过3年（平均9年）。所有患者均通过同步视频脑电图监测确诊为PSS。癫痫发作由闪烁的频闪仪诱发（14例患者），或由患者自身诱发（3例），表现为在光照下点头、看电视时眨眼或近距离观看条纹图案。PSS包括肌阵挛发作（8例患者）、全身强直阵挛性惊厥（5例）、部分性发作（3例）或不典型失神发作（1例）。根据国际癫痫综合征分类，3例患者被归类为婴儿严重肌阵挛性癫痫，5例为青少年肌阵挛性癫痫。其余9例无法归类为任何特定的癫痫综合征。癫痫发病年龄在7岁及以下的儿童除了有难治性癫痫发作外，还容易出现智力缺陷。
