To assess mean changes in visual acuity, central retinal thickness and macular volume as well as to determine the duration of clinical choroidal neovascularization inactivity after single aflibercept injection in neovascular age-related macular degeneration (nAMD) patients switched from ranibizumab (preliminary date). Methods. Open-label prospective study. The study enrolled 23 patients with nAMD previously treated with ranibizumab.</p> <p><bold>Results</bold>. Mean age of patients was 70.5 years, 16 were women. Mean number of ranibizumab injections given prior to switching to aflibercept was 8.7. After single aflibercept inravitreal injection mean visual acuity has significantly improved from 0.40 to 0.47 Snellen chart. Mean central retinal thickness has significantly reduced from 323.1 to 246.9 μm and mean macular volume has significantly reduced from 7.71 to 6.74 mm3. Duration of choroidal neovascularization (CNV) inactivity was 2.91 months.</p> <p><bold>Conclusion</bold>. Single aflibercept intravitreal injection has resulted in significant visual gain as well as in significant central retinal thickness (CRT) and macular volume reduction. This provides evidence of aflibecept efficacy in nAMD patients previously treated with anti-VEGF. Duration of CNV inactivity provides clinical data supporting aflibercept injection every 8 weeks in nAMD patients.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цели работы</bold>. Оценить изменения функциональных и анатомических показателей макулы, а также определить продолжительность интервала до возобновления признаков экссудативной активности хориоидальной неоваскуляризации после однократного введения афлиберцепта у пациентов с «влажной» возрастной макулярной дегенерацией, ранее получавших антиангиогенную терапию ранибизумабом в условиях реальной клинической практики (предварительные данные).</p> <p><bold>Методы исследования</bold>. Проведено открытое проспективное исследование; группу составили 23 пациента (из них 16 женщин) в возрасте от 50 до 89 (в среднем 70,5 ± 2,3) лет. Перед сменой препарата на афлиберцепт пациенты получили в среднем по 8,7 ± 1,1 инъекции ранибизумаба.</p> <p><bold>Результаты</bold>. После проведения однократной инъекции афлиберцепта было установлено статистически достоверное (p &lt; 0,05) повышение остроты зрения с 0,40 до 0,47. Выявлено достоверное уменьшение центральной толщины сетчатки с 323,1 до 246,9 мкм (p &lt; 0,05), а также объёма макулы с 7,71 до 6,74 мм3 (p &lt; 0,05). Продолжительность подавления активности хориоидальной неоваскуляризации составила 2,91 месяца.</p> <p><bold>Заключение</bold>. При анализе результатов однократного интравитреального введения афлиберцепта выявлено значительное улучшение анатомических и функциональных показателей у пациентов с вВМД, ранее получавших анти-VEGF-терапию. Данные исследования могут свидетельствовать о высокой эффективности афлиберцепта при терапии пациентов с вВМД, имевших опыт предшествующей антиангиогенной терапии. Установлена значительная продолжительность подавления активности хориоидальной неоваскуляризации, указывающая на возможность увеличения интервала между инъекциями афлиберцепта, что соответствует результатам клинических исследований.</p></trans-abstract><kwd-group xml:lang="en"><kwd>neovascular (“wet”) age-related macular degeneration</kwd><kwd>aflibercept</kwd><kwd>switching</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>неоваскулярная («влажная») возрастная макулярная дегенерация</kwd><kwd>афлиберцепт</kwd><kwd>переключение</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
