Проведено офтальмологическое обследование 9 пациентов: 5 взрослых в возрасте от 39 до 64 лет и 4 детей в возрасте от 3 до 6 лет с подтвержденным диагнозом «алкаптонурия».</p></sec><sec><title>Результаты</title><p>Результаты. У всех взрослых пациентов выявлены двусторонняя коричнево-черная пигментация склеры и желто-коричневые отложения в конъюнктиве в области глазной щели паралимбально, выраженность которых коррелировала с возрастом, извитостью и расширением сосудов конъюнктивы в зонах депозитов. У 1 из 4 детей обнаружены минимальные отложения желтоватого пигмента в конъюнктиве у лимба. У пациентов старше 60 лет наблюдались типичные мелкие коричневатые отложения в роговице у лимба в области глазной щели.</p></sec><sec><title>Заключение</title><p>Заключение. Изменения глаз являются одним из наиболее частых клинических проявлений алкаптонурии, типичные симптомы — пигментация склеры, конъюнктивы и роговицы у лимба. Офтальмологическое обследование — неинвазивный информативный метод, который может помочь в ранней постановке диагноза, проведении дифференциальной диагностики, оценки динамики заболевания и эффективности проводимой терапии.</p></sec></abstract><trans-abstract xml:lang="en"><p>Alkaptonuria is rare autosomal recessive multisystem disease, caused by mutations in the homogentisine oxidase gene, which leads to the deposition of metabolites of homogentisic acid in organs and tissues (ochronosis).</p><sec><title>The purpose</title><p>The purpose: to study spectrum of ophthalmic manifestations of alkaptonuria in Russian cohort of patients of different ages.</p></sec><sec><title>Material and methods</title><p>Material and methods.

In all adult patients bilateral brown-black scleral pigmentation and yellow-brown deposits in the conjunctiva in the region of the palpebral fissure were detected paralymbally, the severity of which correlated with age, tortuosity and vasodilation of the conjunctiva in areas of deposits. In 1 out of 4 children minimal deposits of yellow pigment were found in the conjunctiva of the limb. In patients older than 60 years typical small brownish deposits were observed in the cornea near the limb in the region of the palpebral fissure.</p></sec><sec><title>Conclusion</title><p>Conclusion. Eye changes are one of the most common clinical manifestations of alkaptonuria. Typical manifestations are the sclera’s pigmentation, conjunctiva and cornea in the limb. Ophthalmological examination is non-invasive informative method that can help in early diagnosis, differential diagnostics, assessment of the dynamics of the disease and the effectiveness of the therapy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>алкаптонурия</kwd><kwd>охроноз</kwd><kwd>глазной охроноз</kwd><kwd>гомогентизиновая кислота</kwd><kwd>дефицит гомогентизиноксидазы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>alkaptonuria</kwd><kwd>ochronosis</kwd><kwd>ocular ochronosis</kwd><kwd>homogentisic acid</kwd><kwd>homogentisic acid oxidase deficiency</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">Nemethova M., Radvanszky J., Kadasi L., Ascher D.B., Pires D.E.V., Blundell T.L., Porfirio B., Mannoni A., Santucci A., Milucci L., Sestini S., Biolcati G., Sorge F., Aurizi C., Aquaron R., Alsbou M., Lourenço C.M., Ramadevi K., Ranganath L.R., Gallagher J.A., van Kan C., Hall A.K., Olsson B., Sireau N., Ayoob H., Timmis O.G., Le Quan Sang K.H., Genovese F., Imrich R., Rovensky J., Srinivasaraghavan R., Bharadwaj S.K., Spiegel R., Zatkova A.
