В исследование включены 111 пациентов с СД в возрасте 57,62 ± 11,02 года и 111 человек контрольной группы сопоставимого возраста — 53,74 ± 15,98 года, которые прошли комплексное офтальмологическое обследование. Кроме того, всем участникам проведена оптическая когерентная томография переднего сегмента глаза для измерения центральной толщины роговицы (ЦТР) и ЦТЭР. Регистрировались демографические данные, а также данные о длительности СД и уровне сахара в крови.</p></sec><sec><title>Результаты</title><p>Результаты. Средняя ЦТР была значительно выше у диабетиков (514,8 ± 31,15 мкм), чем в контрольной группе (500,87 ± 32,34 мкм; p = 0,001 с 95%-ным доверительным интервалом от 5,527 до 22,33). Средний CCET был ниже у больных с СД (50,15 ± 4,49 мкм), чем в контрольной группе (50,6 ± 5,67 мкм; p = 0,513), однако это различие не было статистически значимым. Выявлена значительная разница в ЦТР между контрольной группой и пациентами с тяжелой непролиферативной и пролиферативной ДР (p = 0,034), однако значимой разницы в ЦТЭР между подгруппами с разными видами ДР обнаружено не было (p &gt; 0,05). Корреляции между ЦТЭР, уровнями HbA1с и длительностью СД не выявлено.</p></sec><sec><title>Заключение</title><p>Заключение. ЦТЭР не различалась у диабетиков и в контрольной группе. Корреляции между ЦТЭР и уровнем сахара в крови, а также длительностью СД не обнаружено. Следовательно, толщина эпителия роговицы, возможно, не является фактором, способствующим развитию диабетической кератопатии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study: a cross-sectional study was conducted to compare the central corneal epithelial thickness (CCET) between patients with diabetes mellitus (DM) and age and gender matched controls. We also explored correlation between CCET and duration of DM, DM control and severity of diabetic retinopathy (DR).</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 111 diabetics aged 57.62 ± 11.02 years and 111 controls of comparable age — 53.74 ± 15.98 years who underwent a comprehensive ophthalmology evaluation. Optical coherence tomography of anterior segment was performed on all participants to measure the central corneal thickness (CCT) and CCET. Demographic data and data on duration of DM and blood sugar control were recorded.</p></sec><sec><title>Results</title><p>Results. The mean CCT was significantly higher in diabetics (Mean = 514.8 ± 31.15 μm) compared to controls (Mean = 500.87 ± 32.34 μm; p-value = 0.001 with 95% CI 5.527 to 22.33). The mean CCET was lower in cases (Mean = 50.15 ± 4.49 μm) compared to controls (Mean = 50.6 ± 5.67 μm; p-value = 0.513) however, it was not statistically significant. A significant difference in CCT was observed between controls and patients with severe nonproliferative DR and proliferative DR (p = 0.034), but no significant difference in CCET was found between any subgroups of degree of DR (p &gt; 0.05). There was no correlation between CCET and HbA1с levels and duration of DM.</p></sec><sec><title>Conclusion</title><p>Conclusion. CCET showed no significant difference between diabetics and controls. There is no correlation between CCET and blood sugar control and duration of DM. Hence, corneal epithelial thickness may not be a contributory factor for diabetic keratopathy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сахарный диабет</kwd><kwd>центральная толщина эпителия роговицы</kwd><kwd>диабетическая ретинопатия</kwd><kwd>длительность диабета</kwd><kwd>центральная толщина роговицы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diabetes mellitus</kwd><kwd>central corneal epithelial thickness</kwd><kwd>diabetic retinopathy</kwd><kwd>duration of diabetes</kwd><kwd>central corneal thickness</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">Magliano D, Boyko EJ.
