Результаты последних исследований демонстрируют значимые изменения фовеальной аваскулярной зоны (ФАЗ) — ее площади, индекса ациркулярности (ИА), соотношения осей ФАЗ и угла ФАЗ до возникновения офтальмоскопических проявлений. Большое количество работ посвящено оценке сосудистой плотности (СП) на уровне отдельных сосудистых сплетений, причем зачастую авторы используют разные методы обработки изображений, разные количественные и качественные параметры. Не менее важным признаком доклинической ДР является формирование неперфузируемых зон (НЗ). ОКТ-А позволяет не только детектировать их на разных уровнях, но и провести вычисления их площади. Изменение извитости ретинальных сосудов, описанное ранее при анализе изображений глазного дна, может быть зарегистрировано и количественно подсчитано на ОКТ-А сканах. Кроме того, в отдельных исследованиях у пациентов без офтальмоскопических признаков ДР были выявлены микроаневризмы (МА). В представленном обзоре проведен анализ современных подходов к оценке ранних ангиографических изменений сетчатки и оценены перспективы ОКТ-ангиографии в совершенствовании диагностических алгоритмов ДР. </p></abstract><trans-abstract xml:lang="en"><p>The introduction of OCT-angiography was a milestone in studying the early stages of diabetic retinopathy (DR). The latest findings show significant changes in foveal avascular zone (FAZ) parameters (FAZ area, FAZ perimeter, acirculatory index, axis ratio, FAZ angle) in diabetes mellitus (DM) patients with no ophthalmoscopic signs of DR. Many research groups evaluate vessel density (VD) in superficial and deep plexuses in these patients using different methods of image postprocessing, different qualitative and quantitative parameters. Nonperfusion areas (NA) are very important findings at the preclinical stage of DR, which can be detected in superficial and deep layers. With OCT-A it is possible not only to reveal them but also to calculate their area. Vascular tortuosity (VT) was described earlier using fundus photography. Nowadays VT can be assessed at the microcirculation level in OCT-A scans. Microaneurysms are the earliest clinical sign of DR. They can be missed in fundus photos, but easily detected with OCT-A. The aim of the current review is to analyze the latest OCT-A findings at the preclinical stage of DR and to discuss the future diagnostic value of OCT-A in DR. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>доклиническая диабетическая ретинопатия</kwd><kwd>ОКТ-ангиография</kwd><kwd>фовеальная аваскулярная зона</kwd><kwd>индекс ациркулярности</kwd><kwd>сосудистая плотность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>preclinical diabetic retinopathy</kwd><kwd>optical coherence tomography angiography</kwd><kwd>foveal avascular zone</kwd><kwd>vessel density</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">Ivanisević M., Stanić R.
