В трех независимых группах изучали вариации калибра ретинальных сосудов (РС) при градиенте гликемии (фактора прогрессирования ДР), после ВЭ без ПЛК и после ИВИ (факторов регресса ДР/ПДР). Изображения сетчатки получали с помощью Heidelberg Retinal tomograph HRT II (Germany).</p></sec><sec><title>Результаты</title><p>Результаты. При повышении уровня гликемии тенденция к увеличению диаметра РС при СД1 и СД2 была выявлена как в глазах без ДР, так и при наличии ДР. Однако при ДР изменения были значимыми. После ВЭ без ПЛК на глазах с ПДР диаметр вен уменьшился на 7 % через 2 месяца после ВЭ и на 14 % — через 18 месяцев (p &lt; 0,01); артерии имели стойкие и значимые изменения калибра уже через 2 месяца. После ИВИ афлиберцепта калибр ретинальных сосудов при диабетическом макулярном отеке (ДМО) значимо уменьшался от первой к третьей инъекции.</p></sec><sec><title>Заключение</title><p>Заключение. Пациенты с СД представляли неоднородную группу по выраженности ретинальных сосудистых реакций в зависимости от наличия или отсутствия ДР. Во всех группах исследования после лечения максимальная корригированная острота зрения повышалась на фоне сужения РС. После ВЭ без ПЛК имелось стойкое и значимое уменьшение диаметров РС. Таким образом, динамика калибра РС может отражать фазы эволюции ДР/ПДР: прогрессирования или регресса. Стойкая ремиссия ПДР может быть достигнута без ЛК «аваскулярных зон» сетчатки.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to study retinal vascular reactions (RVR) with a glycemic gradient, vitrectomy (VE) without panretinal photocoagulation (PRP) and after IVI aflibercept in patients with diabetes mellitus (DM).</p></sec><sec><title>Methods</title><p>Methods. In three independent groups, variations in retinal vessel (RV) caliber were studied with a glycemic gradient (DR progression factor), after VE without PRP and after IVI (DR/PDR regression factors). Retinal images were obtained using Heidelberg Retinal tomograph HRT II (Germany).</p></sec><sec><title>Results</title><p>Results. With an increase in the level of glycemia, the tendency to increase the diameter of the RV in DM1 and DM2 was revealed both in eyes without DR and in the presence of DR. However, only in DR were the changes significant. After VE without PRP in the eyes with PDR, the diameter of the veins decreased by 7 % 2 months after VE and by 14 % after 18 months (p &lt; 0.01); the arteries had persistent and significant changes in caliber after 2 months. After IVI aflibercept, the caliber of retinal vessels in DMO significantly decreased from the first to the third injection.</p></sec><sec><title>Conclusion</title><p>Conclusion. Patients with DM initially represent a heterogeneous group in terms of the severity of RVR, depending on the presence or absence of ДР. After treatment, BCVA indicators improved against the background of retinal vasoconstriction in all study groups. After VE without PRP there was a persistent and significant reduction of PV diameters. Thus, the dynamics of retinal vessel caliber may reflect the phases of DR/PDR evolution: progression or regression. Persistent PDR remission can be achieved without lasercoagulation of the retinal “avascular zones”.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>диабетическая ретинопатия</kwd><kwd>ремиссия</kwd><kwd>калибр сосудов</kwd><kwd>аваскулярные зоны</kwd><kwd>регресс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diabetic retinopathy</kwd><kwd>remission</kwd><kwd>vascular caliber</kwd><kwd>avascular zones</kwd><kwd>neurovascular regression</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">Root H, Mirsky S, Ditzel J.
