反射性癫癎(reflexepilepsy)是指主要由某种特殊因素触发的癫癎发作。而光敏性癫癎(photosensitiveepilepsy,PSE)是反射性癫癎中最常见的一种形式,由视网膜受刺激所诱发,于1885年由Gower首次报道。PSE在西欧国家十分常见(占癫癎患者的2%～10%),其中60%的患者首次发作由看电视引起。其他刺激如:电脑屏幕,舞厅的灯光,穿过树林的阳光,水面反光等亦常有报道。PSE在我国相对少见,近年来,由于我国城乡电视机、个人电脑及游戏机日益普及,PSE的研究理应受到重视。以下就近年来国外对PSE的研究进展作一综述。
Reflex epilepsy (reflexepilepsy) refers to the epileptic seizures triggered mainly by some special factors. Photoepilepsy (photoelepsy, PSE) is the most common form of reflex epilepsy induced by irritation of the retina, first reported by Gower in 1885. PSE is very common in Western European countries (2% to 10% of epileptic patients), of which 60% of the patients first episode caused by watching TV. Other stimuli such as: computer screens, ballroom lighting, sunlight through the woods, surface reflections, etc. are also often reported. PSE is relatively rare in our country. In recent years, due to the increasing popularization of urban and rural TV sets, personal computers and game consoles in our country, PSE research deserves our attention. The following summarizes the research progress of PSE abroad in recent years.
