Обследованы 57 беременных (114 глаз): 28 с СД, из них 17 с диабетической ретинопатией (ДР), и 29 без сопутствующей соматической патологии. С помощью оптической когерентной томографии — ангиографии (ОКТА) оценивали общую площадь зон неперфузии с использованием программного обеспечения прибора, кроме того, проводили объективную оценку изменений доли зон ретинальной неперфузии с помощью предложенного метода с использованием графического редактора.</p></sec><sec><title>Результаты</title><p>Результаты. На протяжении беременности и через 3 мес после родов у пациенток с прогрессированием ДР отмечалось значимое увеличение общей площади зон неперфузии. В III триместре в группе СД показатели доли зон неперфузии по обоим сплетениям были больше, чем в контроле. Установлено увеличение доли зон неперфузии по обоим сплетениям и динамическое увеличение общей площади зон неперфузии сетчатки от I триместра к III и через 3 мес после родов в подгруппе прогрессирования ДР.</p></sec><sec><title>Заключение</title><p>Заключение. ОКТА позволяет оценивать изменения зон неперфузируемой сетчатки у беременных, страдающих СД. Метод объективной оценки динамики зон ретинальной неперфузии дает возможность проводить количественную оценку изменений участков неперфузируемой сетчатки раздельно по поверхностному и глубокому ретинальным сплетениям.</p></sec></abstract><trans-abstract xml:lang="en"><p>Purpose of the study was to investigate the possibility of assessing the dynamics of retinal non-perfusion zones in pregnant women with diabetes mellitus (DM) using a standard and the proposed objective method.</p><sec><title>Material and methods</title><p>Material and methods. Fifty-seven pregnant women (114 eyes) were examined: 28 with DM, including 17 with diabetic retinopathy (DR), and 29 without concomitant somatic pathology. Using optical coherence tomography angiography (OCTA), the total area of non-perfusion zones was assessed using the device software. In addition, an objective assessment of changes in the proportion of retinal non-perfusion zones was performed using the proposed method with a graphic editor.</p></sec><sec><title>Results</title><p>Results. Throughout pregnancy and 3 months after delivery, patients with DR progression showed a significant increase in the total area of non-perfusion zones. In the third trimester, the proportion of non-perfusion zones in both plexuses was higher in the DM group than in the control. An increase in the proportion of nonperfused zones in both plexuses and a dynamic increase in the total area of retinal nonperfused zones from the first trimester to the third trimester and at 3 months postpartum were found in the subgroup with progressive DR.</p></sec><sec><title>Conclusion</title><p>Conclusion. OCTA allows for the assessment of changes in nonperfused retina in pregnant women with DM. This method of objectively assessing the dynamics of retinal nonperfusion zones enables quantitative assessment of changes in nonperfused retina areas separately for the superficial and deep retinal plexuses.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>оптическая когерентная томография — ангиография</kwd><kwd>зоны ретинальной неперфузии</kwd><kwd>диабетическая ретинопатия</kwd><kwd>беременность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>optical coherence tomography — angiography</kwd><kwd>retinal nonperfusion zones</kwd><kwd>diabetic retinopathy</kwd><kwd>pregnancy</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">Филиппов В.М., Петрачков Д.В., Будзинская М.В., Сидамонидзе А.Л.
