Конвергенционная недостаточность представляет собой распространенное расстройство бинокулярного зрения и характеризуется утомляемостью глаз, головными болями и затуманиванием зрения при выполнении зрительных задач на близком расстоянии. Вмешательства, основанные на зрительной терапии, включающие вергентную и окуломоторную тренировку, направлены на улучшение бинокулярной координации и уменьшение сопутствующих симптомов. Новые данные свидетельствуют о том, что краткосрочные структурированные программы зрительной терапии способны улучшить конвергентную функцию и зрительный комфорт, что подчеркивает клиническую значимость эффективных терапевтических подходов для лиц, испытывающих высокие зрительные нагрузки на близком расстоянии.</p></sec><sec><title>   Цель</title><p>   Цель: оценить эффективность краткосрочной программы целенаправленной зрительной терапии в улучшении ближней точки конвергенции и уменьшении симптомов конвергенционной недостаточности у молодых взрослых.</p></sec><sec><title>   Материалы и методы</title><p>   Материалы и методы. Было набрано тридцать участников (18–25 лет), распределенных на две группы: экспериментальную (n = 15), в которой проводилась зрительная терапия, и контрольную (n = 15), без вмешательства. Ближняя точка конвергенции оценивалась до и после обследования с использованием линейки Королевских военно-воздушных сил (RAF, Royal Air Force). Объективную рефракцию определяли с помощью ретиноскопа, также исследовали субъективную рефракцию. Для оценки тяжести состояния использовали опросник симптомов конвергенционной недостаточности (CISS, Convergence Insufficiency Symptom Survey). Экспериментальная группа прошла трехнедельную программу зрительной тренировки, включавшую вергентные и окуломоторные упражнения. Нетерапевтические релаксационные активности использовались только в качестве подготовительных заданий.</p></sec><sec><title>   Результаты</title><p>   Результаты. После трехнедельного вмешательства в экспериментальной группе отмечено уменьшение ближней точки конвергенции с 8,4 ± 1,1 до 7,6 ± 1,0 см, тогда как в контрольной группе наблюдалось незначительное изменение (с 8,3 ± 1,2 до 8,2 ± 1,1 см). Показатели опросника симптомов конвергенционной недостаточности (CISS) значимо снизились в экспериментальной группе (с 33,0 ± 3,8 до 14,0 ± 2,9), при этом в контрольной группе отмечены минимальные изменения (с 32,0 ± 4,1 до 30,5 ± 3,6). Субъективная рефракция не показала значимых изменений силы цилиндра или оси ни в одной из групп.</p></sec><sec><title>   Заключение</title><p>   Заключение. Данное исследование позволило сделать вывод, что структурированная программа зрительной терапии значительно улучшила способность к конвергенции и уменьшила симптомы, ассоциированные с конвергенционной недостаточностью, у молодых взрослых. Полученные результаты указывают на то, что краткосрочные вмешательства могут обеспечивать клинически значимые улучшения бинокулярной функции, особенно у лиц, испытывающих эти симптомы во время продолжительных зрительных задач на близком расстоянии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Background</title><p>   Background. Convergence insufficiency is a common binocular vision disorder characterized by eyestrain, headaches, and blurred vision during near tasks. Vision therapy interventions involving vergence and oculomotor training aim to improve binocular coordination and reduce associated symptoms. Evidence suggests that short-term structured vision therapy programs may improve vergence function and visual comfort, highlighting the clinical importance of effective therapeutic approaches for individuals with high near-work demands.</p></sec><sec><title>   Purpose</title><p>   Purpose: to evaluate the effectiveness of a short-term targeted vision therapy program in improving the near point of convergence (NPC) and reducing symptoms of convergence insufficiency in young adults.</p></sec><sec><title>   Materials and methods</title><p>   Materials and methods. Thirty participants aged 18–25 years were enrolled and divided into two groups: an intervention group (n = 15) that received vision therapy and a control group (n = 15) that received no intervention. NPC was measured before and after the intervention using a Royal Air Force (RAF) rule. Objective refraction was determined by retinoscopy, and subjective refraction was also assessed. Symptom severity was evaluated using the Convergence Insufficiency Symptom Survey (CISS). The intervention group completed a three-week vision therapy program comprising vergence and oculomotor exercises. Non-therapeutic relaxation activities were used only as preparatory tasks.</p></sec><sec><title>   Results</title><p>   Results. Following the three-week intervention, mean NPC decreased from 8.4 ± 1.1 cm to 7.6 ± 1.0 cm in the intervention group, whereas only a minimal change was observed in the control group (from 8.3 ± 1.2 cm to 8.2 ± 1.1 cm). CISS scores decreased significantly from 33.0 ± 3.8 to 14.0 ± 2.9 in the intervention group, compared with a slight decrease from 32.0 ± 4.1 to 30.5 ± 3.6 in the control group. No significant changes in cylinder power or axis were observed in either group.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. The structured vision therapy program improved NPC and reduced symptoms associated with convergence insufficiency in young adults. These findings suggest that short-term interventions may improve binocular function, particularly in individuals who experience symptoms during sustained near work.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>конвергенционная недостаточность</kwd><kwd>ближняя точка конвергенции</kwd><kwd>зрительная терапия</kwd><kwd>нить Брока</kwd><kwd>опросник CISS</kwd><kwd>глазные упражнения</kwd><kwd>нестрабологические бинокулярные аномалии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>convergence insufficiency</kwd><kwd>near point of convergence</kwd><kwd>vision therapy</kwd><kwd>Brock string</kwd><kwd>Convergence Insufficiency Symptom Survey</kwd><kwd>vergence exercises</kwd><kwd>non-strabismic binocular vision anomalies</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы не получали финансирование при проведении исследования и написании статьи</funding-statement><funding-statement xml:lang="en">The authors received no funding for the research or the preparation of this article</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">Cooper J, Jamal N.
