Abstract
Optical coherence tomography angiography (OCTA) is a non-invasive, quantitative tool for imaging the retina and choroid that can visualize the microvasculature in three dimensions. It is widely used for diagnosing and monitoring treatment response for various diseases of the anterior and posterior segments of the eye. A systematic search of the relevant literature was conducted, focusing on the period of the most intensive development and clinical application of OCT angiography. This paper aims to summarize current knowledge of OCTA applications in the diagnosis and monitoring of posterior segment retinal pathologies and to discuss its advantages over traditional imaging techniques.
