Оптическая когерентная томография в диагностике и мониторинге врождённой и ювенильной глаукомы

https://doi.org/10.29413/ABS.2022-7.2.16

Аннотация

Оптическая когерентная томография (ОКТ) в повседневной рутинной практике является методом выбора инструментальной диагностики глаукомы у взрослых. Являясь неинвазивным и безопасным методом визуализации структурных изменений сетчатки и зрительного нерва, метод представляет особую ценность в педиатрической практике. Вместе с тем ОКТ-диагностика у детей сопряжена с определёнными трудностями как при проведении исследования, так и при интерпретации результатов сканирования. В этом обзоре обобщены данные литературы и собственных исследований в диагностике и мониторинге врождённой и ювенильной глаукомы с позиций собственного многолетнего клинического опыта использования оптической когерентной томографии. Рассмотрены физиологические изменения сетчатки и зрительного нерва, акцентировано внимание на необходимости создания педиатрической нормативной базы данных толщины сетчатки, обозначены факторы, определяющие нормальный диапазон полученных данных и позволяющие отличить физиологические процессы от патологических. В качестве примеров представлены клинические случаи, подтверждающие ценность ОКТ при сочетанной патологии.
