Всего в рамках открытого проспективного исследования участвовали 64 пациента (67 глаз), из них 27 мужчин и 37 женщин, с первичной открытоугольной глаукомой (ПОУГ). Всем пациентам проведена имплантация дренажа системы Preserflo™ или непроникающая глубокая склерэктомии после ранее выполненных хирургических вмешательств по поводу ПОУГ (НГСЭ и/или имплантация различных моделей дренажей). Пациенты были разделены на 2 группы — группу Preserflo (группа I, 28 пациентов) и группу НГСЭ (группа II, 36 пациентов). Период наблюдения за пациентами составил 1,0 ± 0,1 года.</p></sec><sec><title>Результаты</title><p>Результаты. В исследуемых группах в раннем послеоперационном периоде диагностировали такие осложнения, как гифема (n = 2 в группе I и n = 3 в группе II) и цилиохориоидальная отслойка (n = 1 в группе I и n = 2 в группе II). В группе I отмечали выраженную гипотонию на 1-е сутки после операции (7,4 ± 1,8 мм рт. ст. по сравнению с 31,0 ± 4,7 до операции). В дальнейшем отмечали увеличение ВГД до 18,3 ± 6,1 за период наблюдения 1 год. У 17 пациентов из 28 (60,7 %) ВГД составляло менее 18 мм рт. ст., из них у 2-х — без медикаментозной терапии, что расценивали как «относительный» и «абсолютный» успех соответственно. В группе II в раннем послеоперационном периоде динамика снижения ВГД была менее выраженной (17,5 ± 3,8 мм рт. ст. в первые сутки после операции с дальнейшим увеличением до 26,6 мм рт. ст. через 1 год наблюдений) даже на фоне максимального медикаментозного режима. Через 1 год наблюдения среднее количество используемых препаратов для снижения ВГД в группе I составило 0,94 ± 0,16, а в группе II — 2,28 ± 0,87 (различия статически значимы, p &lt; 0,05). Частота «относительного» успеха в группе I через 6 месяцев и 1 год наблюдений была значимо выше, чем в группе II (43,4 % против 25 % и 53,6 % против 30,6 % соответственно, p &lt; 0,05).</p></sec><sec><title>Заключение</title><p>Заключение. В работе представлены первые в литературе данные по сравнительному анализу эффективности имплантации дренажа Preserflo и непроникающей глубокой склерэктомии у больных с рефрактерной и неоднократно оперированной первичной открытоугольной глаукомой. Показано преимущество имплантации дренажа Preserflo в отношении гипотензивного эффекта и снижения количества инстилляций гипотензивных препаратов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose: сomparative analysis of the effectiveness of PRESERFLO™ microshunt implantation and multiple NPDS in patients with refractory glaucoma.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. A total of 64 patients (67 eyes), including 27 male and 37 female with primary open-angle glaucoma (POAG), were examined and operated on as part of an open prospective study. All patients underwent implantation of the Preserflo™ drainage system or non-penetrating deep sclerectomy after previously performed surgical interventions for POAG (NPDS and/or implantation of various drainage models). The patients were divided into 2 groups — the Preserflo group (group I, 28 patients) and the NPDS group (group II, 36 patients). The follow-up period was 1.0 ± 0.1 years.</p></sec><sec><title>Results</title><p>Results. In the study groups, complications such as hyphema (n = 2 in group I and n = 3 in group II) and ciliochoroidal detachment (n = 1 in group I and n = 2 in group II) were identified in the early postoperative period. In group I, severe hypotension was noted on day 1 after surgery (7.4 ± 1.8 mmHg compared with 31.0 ± 4.7 before surgery). Subsequently, an increase in IOP was noted to 18.3 ± 6.1 during the follow-up period of 1 year. In 17 out of 28 patients (60.7 %), an IOP of less than 18 mmHg was determined, of which 2 were without drug therapy. It was regarded as a “relative” and “absolute” success, respectively. In group II, in the early postoperative period, the dynamics of the decrease in IOP was less pronounced (17.5 ± 3.8 mmHg on the first day after surgery, with a further increase to 26.6 mmHg after a year of follow-up) even against the background of the maximum medication regimen. In the maximum follow-up period, the average number of drugs was used for reducing the IOP in group I was 0.94 ± 0.16, and in group II — 2.28 ± 0.87 (differences are statically significant, p &lt; 0.05). The frequency of “relative” success in group I after 6 months and 1 year of follow-up was significantly higher than in group II (43.4 % versus 25 % and 53.6 % versus 30.6 %, respectively, p &lt; 0.05).</p></sec><sec><title>Conclusion</title><p>Conclusion. The paper presents the first data in the literature on the comparative analysis of the effectiveness of Preserflo drainage implantation and non-penetrating deep sclerectomy in patients with refractory and repeatedly operated primary open-angle glaucoma. The advantage of the implantation of the Preserflo drainage in relation to the antihypertensive effect and reduction of the number of instillations of antihypertensive drugs have been shown.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>глаукома</kwd><kwd>дренаж</kwd><kwd>Preserflo</kwd><kwd>НГСЭ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>glaucoma</kwd><kwd>drainage</kwd><kwd>Preserflo</kwd><kwd>NPDS</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">никто из авторов не имеет финансовой заинтересованности в представленных материалах или методах</funding-statement><funding-statement xml:lang="en">no author has a financial or property interest in any material or method mentioned</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Tham YC, Li X, Wong TY, Quigley HA, Aung T, Cheng CY.
