Optical coherence tomography angiography (OCTA) is a functional extension of OCT that provides information on retinal and choroidal circulations without the need for dye injections. With the recent development of high-speed OCT systems and efficient algorithms, OCTA has become clinically feasible. In this review article, we discuss the technical principles of OCTA, including image processing and artifacts, and its clinical applications in ophthalmology. We summarize recent studies which qualitatively or quantitatively assess disease presentation, progression, and/or response to treatment.
光学相干断层扫描血管造影（OCTA）是OCT的功能扩展，无需注射染料即可提供视网膜和脉络膜循环的信息。随着高速OCT系统和高效算法的最新发展，OCTA已在临床上变得可行。在这篇综述文章中，我们讨论了OCTA的技术原理，包括图像处理和伪像，及其在眼科中的临床应用。我们总结了最近定性或定量评估疾病表现、进展和/或对治疗反应的研究。
