Диабетическая ретинопатия – это повреждение сетчатки глаза при сахарном диабете вследствие высокого уровня сахара в крови. Это заболевание может привести к слепоте, если болезнь диагностируется и лечится на поздних стадиях развития патологии. Оно вызывает изменения кровеносных сосудов и появление некоторых повреждений, таких, как твердые экссудаты и микроаневризмы. Для диагностики диабетической ретинопатии часто используется метод оценки сосудистых структур на основе изображений глазного дна. Однако даже врачи-офтальмологи не могут обнаружить эти повреждения из-за фоновых помех и их низкого контраста, вследствие чего разработка метода для обнаружения признаков диабетической ретинопатии, в особенности на ранних стадиях, является актуальной.Цель работы. Разработка метода диагностики диабетической ретинопатии с использованием дерева решений на основе изображений глазного дна. Материалы и методы. Применены методы на основе сегментации изображений с выделением характерных признаков и бинарной классификации. Используется верифицированная база данных для оценки точности метода выявления диабетической ретинопатии.Результаты. Разработан алгоритм, включающий методы сегментации сосудов, экссудатов и микроаневризм для выявления диабетической ретинопатии на основе цифровой обработки изображений структуры стенок кровеносных сосудов с использованием бинарной классификации. Получены результаты с применением разработанных методов с высокой точностью обнаружения диабетической ретинопатии с использованием верифицированной базы изображений глазного дна. Чувствительность, специфичность и точность обнаружения диабетической ретинопатии составили соответственно 87.14, 88.50 и 87.81 %.Заключение. Разработанный метод позволяет обнаруживать диабетическую ретинопатию у пациентов на ранних стадиях заболевания с достаточно высокой точностью. Метод также может быть применен в системе поддержки врача для принятия решений при диабетической ретинопатии.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Diabetic retinopathy is a complication of diabetes mellitus caused by high blood sugar levels damaging the retina. Diabetic retinopathy leads to changes in ocular blood vessels and the appearance of solid exudates and microaneurysms. When diagnosed and treated in the late stages, this disease can cause blindness. The most common diagnostic method for diabetic retinopathy is based on ocular fundus imaging. However, the background interference and low contrast of such images significantly hinders the timely detection of vascular lesions. Therefore, the development of a method for detecting signs of diabetic retinopathy, particularly in its early stages, presents a relevant research task.Aim. Development of a method for diagnosing diabetic retinopathy based on an analysis of ocular fundus images using the decision-tree approach.Materials and methods. Methods based on image segmentation with identifying characteristic features and their binary classification were used. A verified database was used to access the accuracy of the proposed method for detecting diabetic retinopathy.Results. A method for detecting signs of diabetic retinopathy was developed, which includes the segmentation of vessels, exudates and microaneurysms based on digital processing of ocular vascular images using binary classification. The developed method showed a high level of diagnostic accuracy. Thus, the sensitivity, specificity and accuracy of diabetic retinopathy detection comprised 87.14, 88.50 and 87.81 %, respectively.Conclusion. The developed method allows diabetic retinopathy to be diagnosed with sufficiently high accuracy. The method can also be used for supporting decision making when managing patients with diabetic retinopathy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>диабетическая ретинопатия</kwd><kwd>глазное дно</kwd><kwd>кровеносные сосуды</kwd><kwd>экссудаты</kwd><kwd>микроаневризмы</kwd><kwd>дерево решений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diabetic retinopathy</kwd><kwd>ocular fundus</kwd><kwd>blood vessels</kwd><kwd>exudates</kwd><kwd>microaneurysms</kwd><kwd>decision tree</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">Диабетическая ретинопатия / Т.
