Под наблюдением находились 85 пациентов (85 глаз) с фокальным ДМО. Пациенты были разделены на две группы в зависимости от применяемого метода лазерного лечения: группу 1 составили 50 пациентов (50 глаз), которым было выполнено навигационное субпороговое лазерное воздействие в микроимпульсном и непрерывном режиме с индивидуальным подбором энергетических параметров по разработанной технологии — проводилась лазерная коагуляция по типу «модифицированной решетки». Лечение осуществляли с помощью навигационной лазерной системы NAVILAS 577S («OD-OS», Германия). Всем пациентам обеих групп была выполнена ОКТ-А высокого разрешения по протоколу Angio Retina 3×3 мм и HD Angio Retina 6×6 мм. Методом ОКТ-А оценивали следующие биомаркеры: сосудистую плотность поверхностного сосудистого сплетения (ПСС), глубокого сосудистого комплекса (ГСК); количество микроаневризм и гиперрефлективных точек; площадь фовеальной аваскулярной зоны, а также кист и зон дезорганизации внутренних слоев сетчатки (ДРИЛ) в различные сроки до и после (1, 3 и 6 мес.) лечения.</p></sec><sec><title>Результаты</title><p>Результаты. По данным ОКТ-А в динамике в результате лечения в группе 1 отмечалось увеличение общей сосудистой плотности с 38,45 ± 0,40 до 44,85 ± 0,66 % в ПСС и с 43,55 ± 0,38 до 44,85 ± 0,66 % в ГСК — к 6 месяцам наблюдения. В группе 2 — общая сосудистая плотность в ПСС увеличилась с 37,40 ± 0,36 до 37,85 ± 0,34 %, в ГСК — с 43,35 ± 0,38 до 44,05 ± 0,41 %. Количество микроаневризм уменьшилось в среднем с 12,00 ± 0,42 до 9,00 ± 0,30 к 3 мес. и до 7,50 ± 0,26 к 6 мес. в группе 1, с 19,00 ± 0,70 до 15,50 ± 0,60 (3 мес.) и 13,00 ± 0,50 (6 мес.) — в группе 2. Количество гиперрефлективных точек уменьшилось в сроки 3 и 6 месяцев в обеих группах. Площадь кист прогрессивно снижалась, а площадь ФАЗ и ДРИЛ была стабильна на протяжении всех сроков наблюдения.</p></sec><sec><title>Заключение</title><p>Заключение. ОКТ-А является высокоинформативным методом диагностики, позволяющим неинвазивно выявлять визуализируемые биомаркеры, а также оценивать результативность навигационного лазерного лечения у пациентов с фокальным ДМО. </p></sec></abstract><trans-abstract xml:lang="en"><p>Purpose — to study visualized biomarkers before and after navigation laser treatment in patients with diabetic macular edema (DMO) using optical coherence tomography-angiography (OCT-A).</p><sec><title>Methods</title><p>Methods. 85 patients (85 eyes) with focal DMO were under observation. The patients were divided into two groups, depending on the method of laser treatment used: group 1 consisted of 50 patients (50 eyes) who underwent navigation sub-threshold laser exposure in micro-pulse and continuous modes with individual selection of energy parameters according to the developed technology (patent RF for invention No. 2752544 of 27.01.2021), in group 2 (35 patients, 35 eyes) laser coagulation was performed according to the type of “modified grid”. The treatment was carried out on the NAVILAS 577S navigation laser system (“OD-OS”, Germany). All patients in both groups underwent high-resolution OCT-A according to the Angio Retina 3×3 mm and HD Angio Retina 6×6 mm protocol. The following biomarkers were evaluated by the OCT-A method: vascular density of the superficial vascular plexus (SCP), deep vascular complex (DCP); the number of microaneurysms and hyperreflective points; the area of the foveal avascular zone, as well as cysts and zones of disorganization of the inner layers of the retina (DRIL), at various times before and after (1, 3 and 6 months) treatment.</p></sec><sec><title>Results</title><p>Results. According to OCT-A, as a result of treatment in group 1, there was an increase in total vascular density from 38.45 ± 0.4 % to 44.85 ± 0.66 % in SCP and from 43.55 ± 0.38 % to 44.85 ± 0.66 % in DCP by 6 months of follow–up. In group 2, the total vascular density in SCP increased from 37.4 ± 0.36 % to 37.85 ± 0.34 %, in DCP from 43.35 ± 0.38 % to 44.05 ± 0.41 %. The number of microaneurysms decreased on average from 12 ± 0.42 to 9 ± 0.3 by 3 months and 7.5 ± 0.26 by 6 months in group 1 and, from 19 ± 0.7 to 15.5 ± 0.6 (3 months) and 13 ± 0.5 (6 months) — in group 2. The number of hyperreflective points decreased in terms of 3 and 6 months in both groups. The area of cysts progressively decreased, and the area of FAZ and DRILS was stable throughout all the follow-up period.</p></sec><sec><title>Conclusion</title><p>Conclusion. OCT-A is a highly informative diagnostic method that allows noninvasively to identify visualized OCT-A biomarkers, as well as to evaluate the effectiveness of navigation laser exposure in patients with diabetic maculopathy with focal diabetic macular edema. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>диабетический макулярный отек</kwd><kwd>оптическая когерентная томография в ангиорежиме</kwd><kwd>навигационное лазерное лечение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diabetic macular edema</kwd><kwd>optical coherence tomography in angio-regime</kwd><kwd>navigation laser treatment</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">Lee R., Wong T.Y., Sabanayagam C.
