Это проявляется накоплением в хрусталике продуктов свободно-радикального окисления. Снижение водорастворимости белков ведет к сорбции незаряженных белков на мембранах клеток, в результате чего нарушается регулярная укладка хрусталиковых мембран. Рассеяние света на складчатых поверхностях мембран хрусталиковых волокон рассматривается в качестве основной причины помутнения хрусталика при катаракте. Наибольшее количество осложнений возникает при экстракции осложненной катаракты, т.к. её развитие связано с наличием какого-либо фонового заболевания, дополнительной глазной патологией и воздействием внешних факторов. </p><sec><title>Цель</title><p>Цель. Повышение эффективности лечения катаракты у пациентов с метаболическим синдромом. </p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Обследованы 115 пациентов (230 глаз) с катарактой различного генеза. Всем пациентам выполнено детальное клиническое и комплексное офтальмологическое обследование, по результатам которого они распределены по группам в зависимости от генеза катаракты. В первой группе (возрастная катаракта) общесоматические расстройства выявлялись только в 4,5% случаев, а во второй группе (осложненная катаракта) — в 100% случаев. Материалом исследования служили слезная жидкость и кровь. В слезе исследовали содержание активного пероксиредоксина 6 (PRDX6) и/или фрагментов его распада, а в крови определяли маркеры метаболического синдрома. </p></sec><sec><title>Результаты</title><p>Результаты. Исследована экспрессия ферментов защиты от окислительного стресса в образцах слезной жидкости и дана сравнительная оценка уровня активности ферментов-антиоксидантов слезной жидкости при окислительном стрессе на фоне терапевтического лечения и после различных видов оперативных вмешательств (факоэмульсификация/ФЭК и экстракапсулярная экстракция катаракты). В послеоперационном периоде у пациентов с возрастной катарактой определяется повышение уровня PRDX6, что подтверждается отсутствием осложнений ФЭК. При осложненной катаракте содержание PRDX6 оказалось в 6 раз ниже, чем у пациентов с возрастной катарактой. </p></sec><sec><title>Заключение</title><p>Заключение. Динамическая оценка лабораторных тестов у пациентов с осложненной катарактой позволила подтвердить или опровергнуть наличие проявлений расстройств общего метаболизма и возможность развития окислительного стресса. На основании исследования протеомного статуса слезы и показателей расстройств метаболизма крови обоснован селективный выбор препаратов местного и системного антиоксидантного действия для предотвращения и стабилизации помутнений хрусталика. </p></sec></abstract><trans-abstract xml:lang="en"><p>Exhaustion of anti-oxidative potential and oxidative stress are considered as trigger mechanisms of cataract development. Products of free radical oxidation are accumulated in lens. Decrease in water solubility of proteins results in the sorption of uncharged proteins on cellular membranes. This affects regular lenticular membrane folding. Light scattering on folded membranes of lenticular fibers is considered as a primary cause of lens opacities in cataract. Most problems occur in complicated cataract surgery as its development is associated with background diseases, ocular pathology, and external factor exposure. </p><sec><title>Aim</title><p>Aim. To increase the efficacy of cataract treatment in metabolic syndrome patients. </p></sec><sec><title>Materials and methods</title><p>Materials and methods. 115 cataract patients (230 eyes) were examined. All patients have undergone detailed clinical and complex eye examination and were divided into 2 groups depending on cataract genesis. In group 1 (age-related cataracts), somatic disorders were diagnosed in 4.5% of cases, in group 2 (complicated cataracts), somatic disorders were diagnosed in 100% of cases. Tear and blood tests were performed. Tear level of active peroxiredoxin 6 (PRDX6) and/or its breakdown fragments in fluid and blood level of metabolic syndrome markers were studied. </p></sec><sec><title>Results</title><p>Results. The expression of oxidative stress protective enzymes in tear fluid was investigated. Comparative assessment of tear antioxidant enzyme activity under oxidative stress in therapeutic and surgical procedures (phaco and ECCE) was performed. Post-operatively, PRDX6 increase was revealed in age-related cataract patients. This is confirmed by the absence of phaco complications. In complicated cataract, PRDX6 level was 6 times lower than in age-related cataract patients. </p></sec><sec><title>Conclusions</title><p>Conclusions. Dynamic analysis of laboratory tests in complicated cataract patients confirmed or disproved the presence of general metabolic disorders and oxidative stress development. Tear proteomic profile and blood metabolic disorder parameters served as a basis for selective choice of topical and systemic antioxidant agents to prevent and stabilize lens opacities. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>окислительный стресс</kwd><kwd>катаракта</kwd><kwd>пероксиредоксин 6.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oxidative stress</kwd><kwd>cataract</kwd><kwd>peroxiredoxin 6.</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">Mirzabekova K.A.
