Optical coherence tomography angiography (OCTA) provides a non-invasive method to obtain angiography of the chorioretinal vasculature leading to its recent widespread adoption. With a growing number of studies exploring the use of OCTA, various biomarkers quantifying the vascular characteristics have come to light. In the current report, we summarize the biomarkers currently described for retinal and choroidal vasculature using OCTA systems and the methods used to obtain them. Further, we present a critical review of these methods and key findings in common retinal diseases and appraise future directions, including applications of artificial intelligence in OCTA .

光学相干断层扫描血管造影 (OCTA) 提供了一种非侵入性方法来获得脉络膜视网膜脉管系统的血管造影，导致其最近被广泛采用。随着越来越多的研究探索 OCTA 的使用，各种量化血管特征的生物标志物已经浮出水面。在本报告中，我们总结了目前使用 OCTA 系统描述的用于视网膜和脉络膜脉管系统的生物标志物以及用于获得它们的方法。此外，我们对这些方法和常见视网膜疾病的主要发现进行了批判性审查，并评估了未来的方向，包括人工智能在 OCTA 中的应用。
