The silicone oil samples showed the presence of saturated and unsaturated fatty acids. During emulsification of silicone the ratio of fatty acids changed: the content of stearic fatty acid in the samples of emulsified oil was higher than in the samples without emulsification by 16.7 % (p = 0.03); there was a tendency to increase the content of linolenic acid against the tendency to decrease myristic, palmitic, palmitoleic, oleic and docosadiene acids. Intravitreal silicone oil is not completely biologically inert and is able to absorb lipophilic substances.</p></abstract><trans-abstract xml:lang="ru"><p>Проанализировано 22 образца силиконового масла после тампонады витреальной полости на содержание жирных кислот с помощью газовой хроматографии. В образцах силиконового масла было выявлено наличие насыщенных и ненасыщенных жирных кислот. При эмульгировании силикона соотношение жирных кислот изменялось: содержание стеариновой жирной кислоты в образцах проэмульгированного масла было больше, чем в образцах без эмульгации на 16,7 % (<italic>р</italic> = 0,03); отмечалась тенденция к повышению содержания линоленовой кислоты на фоне тенденции к снижению миристиновой, пальмитиновой, пальмитолеиновой, олеиновой и докозадиеновой кислот. Интравитреальное силиконовое масло не является полностью биологически инертным и способно поглощать липофильные вещества.</p></trans-abstract><kwd-group xml:lang="en"><kwd>retinal detachment</kwd><kwd>silicone oil</kwd><kwd>emulsification</kwd><kwd>fatty acids</kwd><kwd>gas chromatography</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>отслойка сетчатки</kwd><kwd>силиконовое масло</kwd><kwd>эмульгация</kwd><kwd>жирные кислоты</kwd><kwd>газовая хроматография</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Kulikov A.N., Danilenko E.V., Kuznetsov A.R.
