Recognition of characteristic ischemic patterns by optical coherence tomography helps to predict the degree of visual functions’ recovery. The aim of this study is to present clinical cases of patients with Purcher retinopathy and Purcher-like retinopathy and to observe the dynamics of visual rehabilitation of patients with retinal vascular conditions. Two patients with complaints of central vision loss and skotomata in the visual field were examined. The complex of multimodal visualization included fundus photoregistration with fundus camera, optical coherence tomography and optical coherence tomography-angiography, and microperimetry. Paracentral acute middle maculopathy and acute macular neuroretinopathy are the manifestations of the same ischemic process on different levels of retinal vascular plexuses. The “diffuse” pattern damages in paracentral acute middle maculopathy lead to more permanent structural and functional impairments opposed to the “skip” pattern. The optical coherence tomography allows to predict the possibilities of visual and functional rehabilitation in patients with ischemic damage of retinal vessels.</p></abstract><trans-abstract xml:lang="ru"><p>При ретинопатии Пурчера и пурчероподобной ретинопатии возникают ишемические повреждения на уровне всех трёх капиллярных сплетений сетчатки. Распознавание характерных ишемических паттернов при проведении оптической когерентной томографии помогает прогнозировать степень восстановления зрительных функций пациента. Цель — представить клинические случаи пациентов с ретинопатией Пурчера и пурчероподобной ретинопатией и проследить динамику зрительной реабилитации пациентов с сосудистыми нарушениями в сетчатке. Обследовано 2 пациента с жалобами на снижение зрения и скотомы в поле зрения. Комплекс мультимодальной визуализации включал в себя фоторегистрацию глазного дна на фундус-камере, оптическую когерентную томографию, оптическую когерентную томографию-ангиографию и микропериметрию. Парацентральная острая срединная макулопатия и острая макулярная нейроретинопатия — проявления одного и того же ишемического процесса на разных уровнях сосудистых сплетений сетчатки. Поражения по типу «диффузного» паттерна парацентральной острой срединной макулопатии приводят к более стойким структурным и функциональным нарушениям в отличие от «выпадающего» паттерна. Оптическая когерентная томография позволяет прогнозировать возможности зрительно-функциональной реабилитации пациентов с ишемическими повреждениями сосудов сетчатки.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>Purcher retinopathy</kwd><kwd>Purcher-like retinopathy</kwd><kwd>paracentral acute middle maculopathy</kwd><kwd>acute macular neuroretinopathy</kwd><kwd>capillary plexuses</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ретинопатия Пурчера</kwd><kwd>пурчероподобная ретинопатия</kwd><kwd>парацентральная острая срединная макулопатия</kwd><kwd>острая макулярная нейроретинопатия</kwd><kwd>капиллярные сплетения</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Scharf J, Freund KB, Sadda S, Sarraf D.
