Of these, 415 children (23%) were born at the extreme gestational term (GA ≤ 26 weeks). Regarding the period of hospital stay, the studied patients were divided into two groups: group 1 had 785 children with GA of 23–32 weeks (average, 27.9 ± 1.8 weeks) for 2009–2011, and group 2 had 1016 children with GA 22–32 weeks (average, 28 ± 2.3 weeks) for 2012–2014. The screening and monitoring for ROP were performed in accordance with federal clinical guidelines.</p> <p><bold>Results: </bold>The frequency of ROP in deeply premature infants over the years of observation increased by 31.4%, from 42.8% to 74.2%. ROP prevailed in children with GA 22–26 weeks (92%) compared with more mature (GA 27–32 weeks) newborns–(59.2%). Also, the threshold stages of the disease (Type 1 ROP) developed more often among children (28.9%) with GA up to 27 weeks, and only in 7.1% of cases in children with GA 27–32 weeks. In addition, the number of adverse outcomes in children with stages 3–4 ROP was 4.3% and 1.1%, respectively). This indicator was affected by a significant increase (by 11.4%) in the survival of children with GA 22–24 weeks. At the same time, in children with GA 27–32 weeks, this indicator remained stable for six years.</p> <p><bold>Conclusion: </bold>An increase in the survival rate of deeply premature babies with GA of 22–26 weeks was expected to lead not only to an increase in the incidence of ROP, but also to its severe stages (by 12.2%) and, as a result, an increase in the level of visual impairment from early childhood.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель. </bold>Ретроспективный сравнительный анализ частоты и тяжести проявления ретинопатии недоношенных (РН) в зависимости от срока гестации пациентов в условиях неонатального центра Санкт-Петербурга за периоды 2009–2011 гг. и 2012–2014 гг.</p> <p><bold>Материал и методы.</bold> За период с 2009 по 2014 гг. под нашим наблюдением находился 1801 недоношенный ребенок группы риска РН с гестационным возрастом (ГВ) пациентов 22–32 недели (в среднем 28,0 ± 2,1 недель), из них 415 детей (23%) родились на крайних сроках гестации (ГВ ≤26 недель). Относительно периода пребывания в стационаре исследуемые пациенты были разделены на две группы: 1-я группа – 785 детей с ГВ 23-32 недели (в среднем 27,9 ± 1,8) за период 2009-2011 гг.; 2-я группа – 1016 детей с ГВ 22-32 недели (в среднем 28 ± 2,3) за период 2012-2014 гг. Скрининг и мониторинг РН осуществляли в соответствии с Федеральными клиническими рекомендациями.</p> <p><bold>Результаты.</bold> Частота РН у глубоко недоношенных младенцев за годы наблюдения увеличилась на 31,4% — с 42,8% до 74,2%. РН преобладала у детей с ГВ 22-26 недель (92%) по сравнению с более зрелыми новорожденными (ГВ 27–32 недель) — 59,2%. Пороговые стадии заболевания (РН тип 1) также чаще развивались среди детей (28,9%) с ГВ до 27 недель, а у детей с ГВ 27-32 недель — лишь в 7,1% случаев, как и число неблагоприятных исходов (РН IV–V стадии) (4,3 и 1,1%, соответственно). На данный показатель повлиял существенный рост (на 11,4%) выживаемости детей с ГВ 22–24 недели. В тоже время, у детей с ГВ 27–32 недели эти показатели оставались стабильными в течение шести лет.</p> <p><bold>Заключение. </bold>Увеличение выживаемости глубоко недоношенных детей с ГВ 22–26 недель ожидаемо привело не только к росту частоты РН, но и ее тяжелых стадий (на 12,2%) и, как следствие, повышению уровня инвалидности по зрению с раннего детства.</p></trans-abstract><kwd-group xml:lang="en"><kwd>retinopathy of prematurity</kwd><kwd>active phase</kwd><kwd>gestational age</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ретинопатия недоношенных</kwd><kwd>активная фаза</kwd><kwd>гестационный возраст</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">Katargina LA.
