Optical Coherence Tomography Angiography (OCTA) is a relatively new imaging technique in ophthalmology for the visualization of the retinal microcirculation and other tissues of the human eye. This review paper aims to describe the basic definitions and principles of OCT and OCTA in the most straightforward possible language without complex mathematical and engineering analysis. This is done to help health professionals of various disciplines improve their understanding of OCTA and design further clinical research more efficiently. First, the basic technical principles of OCT and OCTA and related terminology are described. Then, a list of OCTA advantages and disadvantages, with a special reference to blood flow quantification limitations. Finally, an updated list of the basic hardware and software specifications of some of the commercially available OCTA devices is presented.
光学相干断层扫描血管造影（OCTA）是眼科中一种相对较新的成像技术，用于可视化视网膜微循环和人眼的其他组织。这篇综述文章旨在用尽可能直白的语言描述OCT和OCTA的基本定义和原理，而不进行复杂的数学和工程分析。这样做是为了帮助各学科的医疗专业人员更好地理解OCTA，并更高效地设计进一步的临床研究。首先，描述了OCT和OCTA的基本技术原理及相关术语。然后，列出了OCTA的优缺点，特别提及了血流定量限制。最后，给出了一些市售OCTA设备的基本硬件和软件规格的最新列表。
