摘　　要：扫频源相干光断层扫描(SS-OCT)和扫频源相干光断层扫描血管成像(SS-OCTA)与传统的频域OCT/OCTA相比,具有波长更长、扫描深度更深、扫描速度更快、图像采集时间更短等技术优势,可获得从玻璃体深至巩膜层的各层组织清晰成像,也使得更广角的眼底组织(包括血管)成像成为可能。临床医生需要关注将SS-OCT/SS-OCTA新技术带来的丰富信息(包括脉络膜厚度测量更准确,对脉络膜血管和基质为主的病变观察更清楚,鉴别脉络膜和巩膜疾病更容易等)转化为对临床诊疗流程的改善,切实提高临床服务能力,而不是仅仅停留在观察影像特征的水平。Swept-source optical coherence tomography(SS-OCT)and Swept-source optical coherence tomography angiography(SS-OCTA),compared to traditional spectral-Domain OCT/OCTA,have several technical advantages such as longer wavelength,deeper scanning depth,faster scanning speed,and shorter image acquisition time.These advancements allow clear imaging of various layers of tissues from the vitreous to the sclera,and enable wide-angle imaging of retinal and choroidal vasculature.Clinical practitioners need to focus on harnessing the rich information provided by SS-OCT/SS-OCTA technology(including more accurate choroidal thickness measurements,clearer observation of choroidal vascular and stromal-dominant lesions,and easier differentiation between choroidal and scleral diseases)to improve the clinical diagnostic and treatment processes,thus effectively enhancing clinical service capabilities.It is crucial to move beyond solely observing imaging features and actively integrate these advancements into clinical practice.(Ophthalmol CHN,2023,32:451-453)
