The study included 30 children at the age ranging from 5 to 12 years in whom visual evoked potentials (VEP) were investigated within 2 weeks after the appearance of the first signs of the disease. Latency and amplitude of the P100 peak were compared between the patients with varicella and tick-borne encephalitis. It was shown that the conductivity along the visual pathway was disordered (slowed down) in 30% of the patients (P100 latency lenthening) while the functional activity of neurons of the visual cortex was impaired in 40% of them (P100 amplitude lowering). Severely disturbed conductivity of the visual pathway was documented in 3% of the patients. The comparison of visual evoked potentials in the children presenting with varicella and tick-borne encephalitis failed to reveal a significant difference. The results of the present work suggest considerable resistance to the development of anatomical lesions in the visual pathway and enhanced functional susceptibility of neurons of the visual cortex to the general state of the central nervous system in the children presenting with various clinical forms of viral encephalitis.</p></abstract><trans-abstract xml:lang="ru"><p>Представлены результаты исследования состояния зрительного пути при различных формах вирусных энцефалитов у детей. 30 детям в возрасте от 5 до 12 лет проводилось исследование зрительных вызванных потенциалов. Выявлено, что показатели проведения по зрительным путям нарушаются у 30%, а функциональная активность нейронов зрительной коры снижается у 40% пациентов. У 3% пациентов наблюдается выраженное нарушение проведения по зрительным путям. Сравнение показателей зрительных вызванных потенциалов у пациентов с ветряночным и клещевым энцефалитами не выявило достоверных различий. Полученные данные свидетельствуют о большой устойчивости к поражению зрительного пути при энцефалитах и повышенной функциональной восприимчивости нейронов зрительной коры к общему состоянию ЦНС.</p></trans-abstract><kwd-group xml:lang="en"><kwd>visual evoked potentials</kwd><kwd>viral encephalitis</kwd><kwd>neuroinfections</kwd><kwd>children</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>зрительные вызванные потенциалы</kwd><kwd>вирусные энцефалиты</kwd><kwd>нейроинфекции</kwd><kwd>дети</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Gronqvist S., Flodmark O., Tornqvist K.
