She complained of decreased vision for 4 months. The decrease in vision was a result of infectious mononucleosis and conjunctivitis. During the initial examination, typical signs of hysterical amblyopia were observed: a bilateral decrease in visual acuity, loss of field to tubular, and a corresponding impaired orientation in the surrounding space. Reversible changes in visual evoked potentials (VEP) were noted, indicating functional changes in the visual system, impaired color perception. A complete ophthalmological examination was performed, including standard methods and electrophysiological studies. Upon repeated examination after 1 day, complete relief of signs of hysterical amblyopia was noted, namely, an increase in visual acuity to 1.2, expansion of the boundaries of the visual field to normal values, normal binocular and accommodation functions, and normal trichromasia. This case was unique because of the complete restoration of visual functions that occurred spontaneously within 1 day. For the first time, reversible changes in visual evoked potential<bold> </bold>that were not previously described in the literature were revealed, and an undifferentiated violation of color perception was described.</p></abstract><trans-abstract xml:lang="ru"><p>Описан случай истерической амблиопии у девочки 10,5 лет. Больная обратилась с жалобами на снижение зрения в течение 4 месяцев. Связывает снижение зрения с перенесённым инфекционным мононуклеозом и сопутствующим конъюнктивитом. Проведено полное офтальмологическое обследование, включающее стандартные методы, электрофизиологические исследования, оценку цветоощущения. При первичном осмотре выявлено двустороннее снижение остроты зрения до сотых долей, сужение границ поля зрения до трубчатого с соответствующими нарушениями ориентации в окружающем пространстве. Отмечены обратимые изменения в зрительных вызванных потенциалах (ЗВП), свидетельствующие о функциональных изменениях в зрительной системе, нарушение цветоощущения. При повторном осмотре через 1 день отмечалось полное купирование признаков истерической амблиопии: повышение остроты зрения до 1,2, расширение границ поля зрения до нормальных значений, нормальные бинокулярные и аккомодационные функции, нормальная трихромазия, нормальные значения ЗВП. Необычность случая заключается в том, что полное восстановление зрительных функций произошло спонтанно в течение одного дня. Впервые описаны обратимые изменения зрительных вызванных потенциалов, ранее не встречавшиеся в литературе, а также недифференцированное нарушение цветоощущения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hysterical amblyopia</kwd><kwd>hysterical visual loss</kwd><kwd>nonorganic visual loss</kwd><kwd>functional visual loss</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>истерическая амблиопия</kwd><kwd>снижение зрения</kwd><kwd>утрата зрения</kwd><kwd>потеря зрения</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Avetisov ES.
