На фоне широкого применения в современной офтальмологической практике интравитреальных инъекций в настоящее время активно изучается осложняющее их внедрение в полость глаза капель силиконового масла, являющегося смазкой шприцев однократного применения, которыми выполняются манипуляции. Среди нежелательных эффектов их присутствия жалобы пациентов на зрительный дискомфорт, связанный с плавающими помутнениями, а также потенциальная связь с эпизодами внутриглазного воспаления и повышением офтальмотонуса.</p></sec><sec><title>Цель</title><p>Цель: оценить распространённость наличия капель силиконового масла в стекловидном теле у пациентов, получавших лечение многократными интравитреальными инъекциями.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено одноцентровое ретроспективное когортное исследование. Критерий включения: лечение с применением многочисленных (не менее 5) интравитреальных инъекций растворов лекарственных препаратов, выполненных по зарегистрированным показаниям. Исследуемую группу составили 86  глаз 85  пациентов (56  женщин, 29  мужчин; возраст – от 36 до 89 лет, средний – 71,7 года), получивших в среднем 13,2 инъекции растворов различных лекарств.</p></sec><sec><title>Результаты</title><p>Результаты. Капли силиконового масла были обнаружены с помощью биомикроскопии в 57 глазах (66,28 %), с помощью ультразвука – в 76 (88,37 %). Совпадение результатов применения методов зафиксировано в 73,26  % наблюдений. У 7 (8,1 %) пациентов выявлены характерные жалобы. Четыре человека (4,7  %) имели эпизоды асептического витреита в анамнезе. Подтверждена гипотеза о том, что вероятность попадания капель силиконового масла в стекловидное тело возрастает с увеличением числа интравитреальных инъекций. Аналогичная зависимость установлена применительно к вероятности появления у пациентов характерных жалоб, обусловленных наличием капель, и эпизодов асептического витреита.</p></sec><sec><title>Заключение</title><p>Заключение. Выпуск капель силиконового масла из шприцев при интравитреальных инъекциях является актуальной проблемой, требующей дальнейшего изучения. В Российской Федерации ситуация усугубляется отсутствием предзаполненных шприцев с препаратами, разрешёнными для введения в полость глаза, а также отсутствием моделей шприцев, разработанных для применения в офтальмологии. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. At present, intraocular drops of silicone oil, which is a lubricant for disposable syringes used for intravitreal injections, are being actively studied. Among the undesirable effects of their presence are patient’s complaints of visual discomfort associated with floating opacities, as well as a potential connection with episodes of intraocular inflammation and increased intraocular pressure.</p></sec><sec><title>The aim</title><p>The aim: to assess the prevalence of silicone oil droplets in the vitreous in patients treated with multiple intravitreal injections.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A single-center retrospective cohort study was carried out. Inclusion criterion: treatment with multiple (at least 5) intravitreal injections of drug solutions performed according to registered indications. The study group consisted of 86 eyes of 85 patients (56 women, 29 men; age – from 36 to 89 y.o., average – 71.7 y.o.), who received an average of 13.2 injections of solutions of various drugs.</p></sec><sec><title>Results</title><p>Results. Drops of silicone oil were detected by biomicroscopy in 57 eyes (66.28 %) and by ultrasonography in 76 (88.37 %). The coincidence of the results of applying the methods was recorded in 73.26 % of observations. Seven (8.1 %) patients had characteristic complaints. Four patients (4.7  %) had a history of aseptic vitreitis. The  hypothesis was  confirmed that the possibility of silicone oil droplets getting into the vitreous increases with the number of intravitreal injections. A similar relationship was established in relation to the possibility of the appearance of characteristic complaints in patients due to the presence of drops and episodes of aseptic vitreitis.</p></sec><sec><title>Conclusion</title><p>Conclusion. The release of drops of silicone oil from syringes during intravitreal injections is an urgent problem that requires further study. In the Russian Federation, the situation is aggravated by the lack of prefilled syringes with drugs approved for administration into the eye cavity, as well as the lack of syringe models designed for use in ophthalmology. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>интравитреальная инъекция</kwd><kwd>капли силиконового масла</kwd><kwd>шприц</kwd><kwd>биомикроскопия</kwd><kwd>ультразвуковое исследование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>intravitreal injection</kwd><kwd>silicone oil droplets</kwd><kwd>syringe</kwd><kwd>biomicroscopy</kwd><kwd>ultrasonography</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">Ramulu PY, Do DV, Corcoran KJ, Corcoran SL, Robin AL.
