摘　　要：扫频源光学相干断层扫描血管成像(SS-OCTA)检查是近几年提出的一种新型血管成像技术,具有非侵入性、快速、高分辨率、自动化血管分层成像等优势,在眼科相关疾病的早期诊断、疗效评估及监测疾病进展等方面具有很高的价值。基于OCTA的基础,SS-OCTA采用快速调谐的激光器和1050 nm的波长,穿透力更强,对视网膜和脉络膜微血管系统进行无创深度分辨成像,加深了对多种眼部疾病(眼底病变、青光眼、神经退行性疾病等)特征的认识。此外,SS-OCTA也可用于研究眼前节结构,如角膜新生血管的深度和密度、虹膜新生血管治疗前后的变化等。该技术为眼科临床实践提供了一种新的手段。本文就SS-OCTA技术在眼科临床的应用进展进行综述。Swept-source optical coherence tomography angiography(SS-OCTA)is a new vascular imaging technique that was recently proposed.It has the advantages of being non-invasive,quick,high-resolution,and automated vascular stratification imaging.It is extremely helpful in the early diagnosis of ophthalmology-related diseases,as well as in the evaluation of treatment effectiveness and the tracking of disease progression.Based on the foundation of OCTA,SS-OCTA utilizes a fast-tuning laser with a wavelength of 1050 nm for deeper penetration and non-invasive depth-resolved imaging of the retinal and choroidal microvascular systems,deepening the understanding of the characteristics of a wide range of ophthalmic diseases(fundus lesions,glaucoma,neurodegenerative diseases,etc.).The structures of the anterior segment of the eye can also be studied using SS-OCTA,including changes in the depth and density of corneal neovascularization as well as changes in iris neovascularization before and after therapy.This approach provides a novel tool for ophthalmic clinical practice.The development of the clinical use of SS-OCTA technology in ophthalmology is reviewed in this article.
