Abstract: 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)
