Figure 1. Illustration of default layer segmentation of AngioVue, AngioPlex, Spectralis OCTA, AngioScan, and SS OCT Angio.

Figure 1

Spectral-domain optical coherence tomography (SD-OCT) image shows the structure of a healthy human retina (aspect ratio 10:1). All five devices share similar layer definitions of superficial retinal layer (SRL; red), deep retinal layer (DRL; green) and outer retinal layer (ORL; blue) in existence of small deviations. Meanwhile, slab definitions differ greatly at vitreous and choroid level: AngioVue, AngioPlex, and SS OCT Angio segment choriocapillaris (CC; yellow), AngioPlex and AngioScan segment choroid (orange) and AngioPlex segments vitreoretinal interface (VRI; purple).
