Материал и методы. Ретроспективно изучены данные ОКТ 112 пациентов (112 глаз), осмотренных на двух аппаратах Cirrus HD-OCT (Carl Zeiss Meditec) последовательно в течение 3 (исследования макулярной области, 67 человек) и 5 (исследования области диска зрительного нерва (ДЗН), 62 человека) дней, в том числе 17 человек, которым проводились исследования обоих видов. На предмет наличия артефактов оценивали как исходные данные сканирования (B-сканы), так и результаты их последующего анализа. Результаты. Предложены критерии артефактов ОКТ и их рабочая классификация, выделяющая три вида артефактов: ошибки сегментирования / определения границ ДЗН, «срезание» скана и смещение/выпадение сканов, а также 8 основных причин ошибок. Частота артефактов варьировала от 19 % (анализ области ДЗН) до 37 % (анализ макулярной области) и 65 % (оценка макулярного слоя ганглиозных клеток с внутренним плексиформным). Наиболее распространены были ошибки сегментирования у пациентов с резко выраженными нарушениями или эпиретинальными мембранами (фиброзом). Заключение. Клинически значимые артефакты ОКТ встречаются в 19–65 % случаев в зависимости от анализируемых структур глазного дна. Наиболее распространены ошибки сегментирования у пациентов с резко выраженными нарушениями и эпиретинальными мембранами (фиброзом). Предложена рабочая классификация артефактов ОКТ, выделяющая три основных их вида и наиболее важные причины их появления.</p></abstract><trans-abstract xml:lang="en"><p>Purpose. To study and classify artifacts of spectral-domain optical coherence tomography (OCT).  Material and methods. The retrospective study included OCT data of 112 patients (112 eyes)  examined on two Cirrus HD-OCTs (Carl Zeiss Meditec) sequentially for three days (macular area examinations, 67 patients) and five days (examination of the optic disc region, 62 people), including 17 people who underwent both types of examination. Both the original scanning data (B-scans) and the results of their subsequent analysis were evaluated for the presence of artifacts. Results. The criteria of OCT artifacts were suggested and their practical classification was proposed, which distinguishes three types of artifacts: segmentation errors/errors in delineation of the optic disc borders, "out-of-register" artifacts and displacement/fallout of B-scans, and eight main causes of artifacts. The frequency of artifacts ranged from 19 % (analysis of the optic disc area) to 37 % (analysis of the macular area) and 65 % (evaluation of the ganglion cell-inner plexiform layer). The most common were segmentation errors in patients with pronounced pathology or epiretinal membranes (fibrosis). Conclusion. Clinically significant OCT artifacts occur in 19–65 % of cases, depending on the analyzed eye fundus structures. The most common artifacts are segmentation errors in patients with pronounced pathology and epiretinal membranes (fibrosis). A practical classification of OCT artifacts is proposed, which distinguishes three main types and the most important causes of their presence.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оптическая когерентная томография</kwd><kwd>артефакты</kwd><kwd>классификация</kwd><kwd>диск зрительного нерва</kwd><kwd>макулярная область</kwd><kwd>слой ганглиозных клеток с внутренним плексиформным</kwd></kwd-group><kwd-group xml:lang="en"><kwd>optical coherence tomography</kwd><kwd>artifacts</kwd><kwd>classification</kwd><kwd>optic disc</kwd><kwd>macular area</kwd><kwd>ganglion cell-inner plexiform layer</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">Artifact.
