Пациенты и методы. Под наблюдением находились 12 пациентов (15 глаз) с кератоконусом 1–2-й стадии по классификации Amsler-Kruimerich. Всем пациентам была выполнена процедура УФ-кросслинкинга по стандартному «Дрезденскому» протоколу с 0,1%-ным водным раствором рибофлавина. Для оценки локализации демаркационной линии пациентам проводили оптическую когерентную томографию переднего отрезка глаза с помощью аппарата DRI OCT Triton (Topcon, Япония) в разных зонах роговицы. Результаты. После выполнения стандартного кросслинкинга роговицы демаркационная линия выявлялась в большинстве случаев через 1 месяц (87%). При биомикроскопии демаркационная линия ограничивала передний и средний слои стромы от заднего слоя. Глубина залегания стромальной демаркационной линии по данным ОКТ в центре составляла в среднем 305,73 ± 41,08 мкм (диапазон 282–345 мкм), назально — 215,16 ± 35,5 мкм (диапазон 160–289 мкм), темпорально — 205,23 ± 32,81 мкм (диапазон 190–276 мкм). Отмечено достоверно значимое различие в глубине локализации демаркационной линии в центральной зоне роговицы (глубже) и 6-мм зоне (р &lt; 0,001). Заключение. Демаркационная линия роговицы являетсяодним из показателей глубины фотохимического процесса сшивания коллагена в ткани роговицы. Оптимальные сроки выявления демаркационной линии после кросслинкинга роговичного коллагена составляют от 2 недель до 3 месяцев. Глубина демаркационной линии в исследуемых зонах роговицы различна, в центральной зоне она глубже относительно периферических зон.</p></abstract><trans-abstract xml:lang="en"><p>Purpose: To assess the topographic location of the demarcation line in in different areas of the cornea after standard corneal crosslinking.Patients and methods. 12 patients (15 eyes) with keratoconus of stages 1–2 of Amsler-Kruimerich classification were observed. UV cross-linking was performed in all patients according to the standard Dresden protocol with 0.1% aqueous solution of riboflavin. The patients underwent optical coherence tomography of the anterior segment of the eye on “DRI OCT Triton” (“Topcon”, Japan) in different areas of the cornea to assess the location of the demarcation line. Results. Demarcation line was revealed in1 month after standard corneal cross-linking in most cases (87%). Biomicroscopy showed that DL limited the anterior and middlelaers of the stroma from the posterior one. The stromal demarcation line depth according to OCT averaged 305.73 ± 41.08 μm (range of 282–345 μm) at the center, nasally — 215.16 ± 35.5 μm (range of 160–289 μm) and temporally 205,23 ± 32.81 μm (range of 190–276 μm). A significant difference in the depth of DL localization in the central zone of the cornea and a 6 mm zone (p &lt; 0.001) was noted. Conclusion. The corneal stromal (обычно) demarcation line is one of the indicators of the depth of photochemical process of corneal cross-linking. Optimal timing of detection of DL following corneal collagen crosslinking is 2 weeks — 3 months. The depth of DL in the corneal studied areas is different; it is deeper in the central zone than in the peripheral ones.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кератоконус</kwd><kwd>кератэктазия</kwd><kwd>кросслинкинг роговицы</kwd><kwd>демаркационная линия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>keratokonus</kwd><kwd>keratoectasia</kwd><kwd>corneal crosslinking</kwd><kwd>demarcation line</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.
