The diversity of etiological factors, the absence of pronounced corneal syndrome, and the similarity of early manifestations to other ocular surface disorders frequently result in delayed diagnosis and complicate treatment selection. Therefore, a comprehensive approach to the examination of patients with neurotrophic keratopathy remains highly relevant, as it allows objective assessment of disease severity and monitoring of pathological changes during treatment. Report the case of a 69-year-old woman with a persistent postherpetic corneal erosion of the right eye lasting for four months and refractory to conservative treatment. The patient complained of decreased vision and a foreign body sensation. Best-corrected visual acuity was 0.08. Slit-lamp examination revealed an epithelial defect involving 7.6% of the corneal surface, accompanied by perifocal and stromal edema. Corneal sensitivity was absent at all nine examined points. Anterior segment optical coherence tomography demonstrated a minimum corneal thickness of 609 μm. In vivo confocal microscopy revealed marked depletion of the subbasal nerve plexus, with a corneal nerve fiber density of 4 fibers/mm<sup>2</sup>, a corneal nerve branch density of 3 branches/mm<sup>2</sup>, and a corneal nerve fiber length of 662 mm/mm<sup>2</sup>. An extended diagnostic algorithm incorporating clinical, functional, and instrumental examinations was used for comprehensive assessment of the ocular surface and subsequent follow-up. Following sublimbal orbital fat transposition (S-LOFT), involving transposition of the inferomedial orbital fat pad beneath a scleral flap to the limbal area, complete corneal epithelialization was achieved, with no recurrence of epithelial defects during the 12-month follow-up post-S-LOFT period. This clinical case demonstrates the practical value of an extended diagnostic algorithm for patients with neurotrophic keratopathy. Comprehensive evaluation of the ocular surface enables timely diagnosis, objective assessment of pathological changes, rational selection of treatment strategy, and monitoring of therapeutic outcomes.</p></abstract><trans-abstract xml:lang="ru"><p>Нейротрофическая кератопатия (НТК) представляет собой редкое дегенеративное заболевание роговицы, обусловленное нарушением ее иннервации и характеризующееся снижением чувствительности и развитием трофических нарушений, что могут приводить к возникновению и персистенции дефектов. Разнообразие этиологических факторов, отсутствие выраженного роговичного синдрома и сходство ранних проявлений с другими заболеваниями глазной поверхности нередко приводят к поздней диагностике и затрудняют выбор лечебной тактики. В связи с этим актуальным остается применение комплексного подхода к обследованию пациентов с НТК, позволяющего объективизировать степень поражения и отслеживать динамику патологического процесса на фоне проводимого лечения. Представлен клинический случай пациентки Ц., 69 лет, с персистирующей в течение четырех месяцев постгерпетической эрозией роговицы правого глаза, резистентной к проводимой консервативной терапии. Пациентка предъявляла жалобы на снижение зрения и чувство инородного тела. Максимально корригированная острота зрения составляла 0,08. При биомикроскопии выявлен дефект эпителия роговицы площадью 7,6 %, сопровождавшийся перифокальным отеком и отеком стромы. Чувствительность роговицы отсутствовала во всех девяти исследуемых точках. По данным оптической когерентной томографии минимальная толщина роговицы составила 609 мкм. Конфокальная биомикроскопия выявила выраженное обеднение суббазального нервного сплетения: плотность нервных волокон составляла 4 волокна/мм<sup>2</sup>, плотность их ветвей — 3 ветви/мм<sup>2</sup>, длина нервных волокон — 662 мм/мм<sup>2</sup>. Для комплексной оценки состояния глазной поверхности и последующего мониторинга был применен расширенный диагностический алгоритм, включающий клинические, функциональные и инструментальные методы исследования. После выполнения сублимбального перемещения орбитальной клетчатки, включающего перемещение нижнего медиального пакета орбитальной клетчатки под склеральный лоскут к лимбу, была достигнута полная эпителизация роговицы, а в течение 12 месяцев наблюдения рецидивов деэпителизации не отмечено. Представленный клинический случай демонстрирует практическую значимость расширенного алгоритма обследования пациентов с НТК. Комплексная оценка состояния глазной поверхности позволяет своевременно верифицировать диагноз, объективизировать выраженность патологических изменений, обосновать выбор лечебной тактики и осуществлять мониторинг эффективности проводимого лечения.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>neurotrophic keratopathy</kwd><kwd>neurotrophic keratitis</kwd><kwd>examination algorithm</kwd><kwd>confocal microscopy</kwd><kwd>corneal ulcer</kwd><kwd>vital dyes</kwd><kwd>optical coherence tomography</kwd><kwd>case report</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>нейротрофическая кератопатия</kwd><kwd>нейротрофический кератит</kwd><kwd>алгоритм обследования</kwd><kwd>конфокальная биомикроскопия</kwd><kwd>язва роговицы</kwd><kwd>витальные красители</kwd><kwd>оптическая когерентная томография</kwd><kwd>клинический случай</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Lambiase A, Sacchetti M.
