В исследование включены 34 пациента с ПДР и осложненной начальной катарактой, разделенных на две группы. В I группе первый этап — ВРХ с силиконовой тампонадой, второй этап — ФЭК c имплантацией ИОЛ одновременно с плановым удалением силиконового масла (СМ). Во II группе первый этап — ФЭК с имплантацией ИОЛ одномоментно с ВРХ + силиконовая тампонада. Второй этап — удаление СМ из витреальной полости. У пациентов обеих групп исследованы образцы СЖ до операции и на 2-е сутки после первого этапа хирургического лечения.</p></sec><sec><title>Результаты</title><p>Результаты. Во II группе по сравнению с I группой на 2-е сутки после первого этапа хирургического лечения повышены в 2,5–5 раз концентрации в СЖ IL-8, MCP-1, ICAM-1.</p></sec><sec><title>Заключение</title><p>Заключение. Повышение концентрации цитокинов IL-8, MCP-1 и ICAM-1 в СЖ после одновременного выполнения ФЭК с имплантацией ИОЛ и ВРХ в сравнении с просто ВРХ указывает на необходимость дальнейшего изучения роли воспалительного компонента в патогенезе развития послеоперационных осложнений у пациентов с далеко зашедшей стадией ПДР.</p></sec></abstract><trans-abstract xml:lang="en"><p> The purpose is to estimate the content of pro- and anti-inflammatory cytokines (IL-1 , IL-8, IL-10, MCP-1, ICAM-1, VEGF) in the tear liquid of patients with advanced proliferative diabetic retinopathy (PDR) and  complicated primary cataract after phacoemulsification and IOL implantation performed simultaneously with vitreoretinal surgery vs. vitreoretinal surgery  alone. </p><sec><title>Material and methods</title><p>Material and methods. 34 patients  with PDR and complicated primary  cataract were divided into two groups. Group 1 received a two-phase  surgical procedure: (a) vitreoretinal surgery (VRS) with silicone oil tamponade followed by (b) phacoemulsification surgery, IOL implantation and silicone oil removal. Group 2 was subjected to (a) phacoemulsification simultaneously with vitreoretinal surgery and silicone oil tamponade and (b) silicone oil  removal from the vitreous cavity. Both groups had their tear liquid samples examined before the surgery and on the 2nd day after the 1stphase. </p></sec><sec><title>Results</title><p>Results. Group 2 revealed a 2 to 2.5 times higher concentration of IL-8, MCP-1 and ICAM-1 as compared to Group 1. </p></sec><sec><title>Conclusion</title><p>Conclusion. Increased concentrations of IL-8, MCP-1, and ICAM-1 in the tear  after phacoemulsification surgery and IOL implantation coupled with  vitreoretinal surgery as compared to vitreoretinal surgery alone requires additional research of the role played by the inflammatory component in the  pathogenesis of postsurgical complications in advanced PDR patients. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>цитокины</kwd><kwd>пролиферативная диабетическая ретинопатия</kwd><kwd>витреоретинальная хирургия</kwd><kwd>факоэмульсификация катаракты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cytokines</kwd><kwd>proliferative diabetic retinopathy</kwd><kwd>vitreoretinal surgery</kwd><kwd>phacoemulsification</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">Петрачков Д.В., Казаков И.С., Артемов М.А., Аржуханов Д.Д.
