The injection technique demonstrated that the dispersed dye is found at all levels of trabecular outflow in the area of trabecular meshwork scraping compared with the intact area, where the dye spread is limited by the trabecular meshwork and Schlemm canal.</p> <p><bold>CONCLUSION:</bold> This experimental study of the trabecular meshwork after manual trabeculotomy suggests a possible improvement in aqueous outflow.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Изучение морфологических изменений трабекулярного аппарата, возникающих после выполнения механического трабекулопилинга, представляет собой интерес с целью обоснования гипотензивного эффекта данной процедуры.</p> <p><bold>Цель исследования.</bold> Оценка изменений трабекулярного аппарата угла передней камеры после экспериментального моделирования механического трабекулопилинга <italic>ex vivo</italic>.</p> <p><bold>Методы.</bold> После экспериментального моделирования <italic>ex vivo </italic>механического трабекулопилинга 4 кадаверных глаза были использованы для изучения морфологии трабекулярного аппарата с помощью сканирующей электронной микроскопии, 4 кадаверных глаза — для визуализации путей оттока внутриглазной жидкости с использованием инъекционной методики.</p> <p><bold>Результаты.</bold> Анализ результатов сканирующей электронной микроскопии показал, что механический трабекулопилинг приводит к частичному слущиванию увеальной части трабекулы с полной сохранностью эндотелия роговицы. В результате инъекционной методики выявлено, что в зоне воздействия трабекулоскреппером дисперсный краситель обнаруживается на всех уровнях трабекулярного пути оттока внутриглазной жидкости в отличие от интактной зоны, где распространение туши ограничивается трабекулой и шлеммовым каналом.</p> <p><bold>Заключение.</bold> Результаты экспериментального исследования трабекулярного аппарата глазного яблока после выполнения механического трабекулопилинга позволяют нам сделать вывод о возможном улучшении проходимости путей оттока внутриглазной жидкости.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>trabecular meshwork</kwd><kwd>manual trabeculotomy</kwd><kwd>trabecular meshwork scraper</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>трабекулярная сеть</kwd><kwd>механический трабекулопилинг</kwd><kwd>трабекулоскреппер</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Nesterov AP.
