Проведен ретроспективный анализ данных амбулаторных медицинских карт 62 пациентов (62 глаза) с кератэктазиями и наличием кератотопограммы «клешни краба». Во всех глазах проводили оптическую когерентную томографию роговицы и с помощью Pentacam изучали параметры кератопахиметрии и элевацию роговицы.</p></sec><sec><title>Результаты</title><p>Результаты. Оптическая когерентная томография позволила во всех случаях определить локализацию зоны истончения роговицы. Только 5 из 13 показателей кератопахиметрии имели статистически значимые межгрупповые различия и могут быть использованы в дифференциальной диагностике кератэктазий.</p></sec><sec><title>Заключение</title><p>Заключение. Проведенный анализ показал, что, в отличие от кератотопографии, кератопахиметрия и оптическая когерентная томография роговицы позволяют дифференцировать вид первичной кератэктазии, в отличие от КТГ, КПМ и ОКТ роговицы, которые позволяют дифференцировать вид ПКЭ. Наибольшую ценность в комплексной диагностике ПМДР представляют определение КТГ-паттерна, ОКТ и ΔКПМ. Применение Шеймпфлюг-камеры в обследовании глаз с ПКЭ (первичная кератэктазия) наиболее оправданно, поскольку на основании полученных данных можно не только установить вид ПКЭ, но и оценить роговичный статус в динамике и определить тактику лечения. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose. To analyze the significance of keratotopography, keratopachymetry and optical coherence tomography of the cornea in the differential diagnosis of pellucid marginal corneal degeneration with keratoconus.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. A retrospective analysis of data from outpatient medical records of 62 patients (62 eyes) with keratectasias and the presence of a crab claw keratotopogram was carried out. Optical coherence tomography of the cornea was performed in all eyes and the parameters of keratopachymetry and corneal elevation were studied on the Pentacam.</p></sec><sec><title>Results</title><p>Results. Optical coherence tomography allowed in all cases to determine the localization of the corneal thinning zone. Only 5 out of 13 indicators of keratopachymetry had statistically significant intergroup differences and can be used in the differential diagnosis of keratectasias.</p></sec><sec><title>Conclusion</title><p>Conclusion. The analysis showed that, in contrast to keratotopography, keratopachymetry and optical coherence tomography of the cornea make it possible to differentiate the type of primary keratectasia. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>первичные кератэктазии</kwd><kwd>пеллюцидная маргинальная дегенерация роговицы</kwd><kwd>кератоконус</kwd><kwd>кератотопография</kwd><kwd>кератопахиметрия</kwd><kwd>оптическая когерентная томография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>primary keratectasias</kwd><kwd>pellucid marginal corneal degeneration</kwd><kwd>keratoconus</kwd><kwd>keratotopography</kwd><kwd>keratopachymetry</kwd><kwd>optical coherence tomography</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Бикбов М.М., Бикбова Г.М.
