[Retinal pigment epithelial tear in age-related macular degeneration]

Retinal pigment epithelial tear (RPET) occurs in a number of diseases, most often in age-related macular degeneration (AMD). RPET develops in the setting of retinal pigment epithelium (RPE) detachment and represents a violation of the integrity of its monolayer accompanied by the formation of a demarcation line between the RPE atrophy area and RPE folds. Its incidence varies widely. In the earlier studies, diagnosis of RPET was performed using fluorescent angiography or angiography with indocyanine green (ICG-FA). The advent of optical coherence tomography made the detection of RPET easier and more accessible. The mechanism of RPET formation is quite polymorphic and ambiguous. Scientific literature contains descriptions of the occurrence of RPET when using both ranibizumab and aflibercept, and bevacizumab in equal proportions, implying that the drug choice does not affect the occurrence of complications. Continuous monitoring and adherence to anti-VEGF therapy leads to better anatomical and functional results in the long term, which is crucial for improving the quality of life of patients with age-related macular degeneration. This article reviews the literature and presents current data on RPET, identifies risk factors and mechanisms of its development, provides classification, and describes modern options for its diagnosis and treatment.
