Актуальным остается поиск контрастирующего агента, имеющего максимальный профиль безопасности, при этом интенсивно и селективно окрашивающего структуры стекловидного тела и витреоретинального интерфейса.</p><sec><title>Цель исследования</title><p>Цель исследования: провести исследование жизнеспособности клеток культуры фибробластов мыши линии NIH/3T3 при сравнительном воздействии традиционных агентов для хромовитрэктомии и суспензии «Витреоконтраст» изолированно и в условиях эндовитреального освещения.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В культуру фибробластов мыши линии NIH/3Т3 вносили агенты для хромовитрэктомии (MembraneBlue® Dual, Триамцинолона ацетонид (ТА), суспензию «Витреоконтраст»). Тестовый планшет подвергали облучению осветителем «Photon II», рабочее расстояние 5 мм. Контрольный планшет с внесенными препаратами облучению не подвергали. Далее клетки промывали и инкубировали, после чего оценивали морфологию и лизис клеток, а также количество пролиферирующих относительно отрицательного контроля фибробластов с помощью витального красителя PrestoBlue® Cell Viability Reagent. Отрицательным контролем служила полная ростовая среда для культивирования фибробластов мыши линии NIH/3T3. Полученные результаты цитотоксической реакции культуры фибробластов мыши линии NIH/3Т3 интерпретировали с использованием таблицы «Степень ответной реакции клеток».</p></sec><sec><title>Результаты</title><p>Результаты. Проведенные исследования показали, что облучение источником эндовитреального освещения не влияет на цитотоксическое действие суспензии ТА и красителя MembraneBlue® Dual. Суспензия ТА как после облучения, так и без облучения оказывает умеренное цитотоксическое действие, а MembraneBlue® Dual не оказывает цитотоксического действия на культуру фибробластов мыши линии NIH/3T3. Без облучения суспензия «Витреоконтраст» не оказывает цитотоксического действия на культуру фибробластов мыши линии NIH/3T3. Облучение в течение 1 ч повышает цитотоксичность суспензии «Витреоконтраст» до уровня нерезкой цитотоксичности, допустимого ГОСТ ISO 10993-5-2011.</p></sec><sec><title>Заключение</title><p>Заключение. Профиль безопасности агентов для хромовитрэктомии MembraneBlue® Dual и «Витреоконтраст» позволяет рекомендовать их для использования в ходе эндовитреальной хирургии. Продемонстрированная в эксперименте цито- и фототоксичность суспензии ТА может снижать функциональные исходы хирургии сетчатки. </p></sec></abstract><trans-abstract xml:lang="en"><p>Intravitreal use of vital dyes in combination with the action of endoillumination can induce a cyto- and phototoxic effect on posterior eye segment structures. The search for a staining agent with a maximum safety profile to retinal structures, intensively and selectively coloring vitreous body and vitreoretinal interface structure, remains relevant.</p><sec><title>Objective</title><p>Objective: to determine comparative viability of NIH / 3T3 mouse fibroblast cell culture with traditional agents for chromovitrectomy and “Vitreocontrast” suspension with and without endovitreal illumination.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. NIH / 3T3 mouse fibroblast cultures contacted with agents for chromovitrectomy (MembraneBlue® Dual, Triamcinolone acetonide, “Vitreocontrast” suspension) and the corresponding controls in a volume of 50 μl / well. The test plate was irradiated with a Photon II illuminator (Synergetics, USA), working distance of 5 mm. The control tablet with the introduced preparations was not exposed to light. Next, the cells were washed and incubated, after which the morphology and lysis of the cells, as well as the number of proliferating relatively negative control of fibroblasts, were evaluated using the vital dye PrestoBlue Cell Viability Reagent. Negative control was the complete growth medium for the cultivation of mouse fibroblasts of the NIH / 3T3 line. The results of the cytotoxic reaction of a culture of mouse fibroblasts of the NIH / 3T3 line were interpreted using the table “The degree of cell response”.</p></sec><sec><title>Results</title><p>Results. Studies have shown that exposure to a source of endovitual illumination does not affect the cytotoxic effect of TA suspension and MembraneBlue® Dual dye. The TA suspension, both after light source and without it, has a moderate cytotoxic effect, and MembraneBlue® Dual has no cytotoxic effect on the culture of mouse fibroblasts of the NIH / 3T3 strain. Without light, “Vitreocontrast” suspension does not have cytotoxic effect on mouse fibroblasts culture NIH / 3T3 line. Light irradiation for 1 h increases the cytotoxicity of “Vitreocontrast” suspension to the level of unsharp cytotoxicity allowed by ISO Standard 10993-5-2011.</p></sec><sec><title>Conclusion</title><p>Conclusion. The safety profile of MembraneBlue® Dual and “Vitreocontrast” suspension allows them to be recommended for use in endovitreal surgery. The cyto- and phototoxicity demonstrated in the experiment with TA suspension can reduce the functional outcomes of retinal surgery. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>витреоконтраст</kwd><kwd>интравитреальные красители</kwd><kwd>триамцинолона ацетонид</kwd><kwd>витреомакулярный интерфейс</kwd><kwd>внутренняя пограничная мембрана</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vitreocontrast</kwd><kwd>intravitreal dyes</kwd><kwd>triamcinolone acetonide</kwd><kwd>vitreomacular interface</kwd><kwd>inner boundary membrane</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">Chow D.R.
