ПНО часто возникает совместно с другими системными проявлениями митохондриальной дисфункции. Правильная и ранняя диагностика ПНО первостепенна для оптимального ведения данных пациентов. В статье представлен обзор последних данных по этиологии, спектру клинических проявлений, дифференциальному диагнозу, методам диагностики и лечебным опциям для изолированной хронической ПНО и других ПНО-ассоциированных митохондриальных синдромов.</p></abstract><trans-abstract xml:lang="en"><p>Progressive  external ophthalmoplegia  (PEO) is characterized  by progressive  bilateral ptosis and eye movement disturbances in horizontal and vertical directions and represents a typical symptom of many mitochondrial disorders, but not a separate disease. PEO often occurs together with other systemic manifestations of mitochondrial disfunction. Correct and early diagnosis of PEO is essential for optimal management of these patients. In this review we collected the last data about etiology, spectrum of clinical symptoms, differential diagnosis, diagnostical methods and treatment options for isolated chronic PEO and other PEO-associated mitochondrial syndromes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>прогрессирующая  наружная офтальмоплегия</kwd><kwd>митохондриальное  заболевание</kwd><kwd>синдром Кернса–Сейра</kwd><kwd>офтальмоплегия</kwd><kwd>миопатия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>progressive external ophthalmoplegia</kwd><kwd>mitochondrial disorder</kwd><kwd>Kearns–Sayre syndrome</kwd><kwd>ophthalmoplegia</kwd><kwd>myopathy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Von Graefe A.
