Information
Fig1: Both superior and inferior boundaries of CO can be clearly identified on HD B-scan (red arrows). Lamellar structures inside CO. Besides, interruption of ellipsoid zone, local PED and dystrophy were found.
Fig2: Elevation and excavation of choroid in different orientations on radial lines scan.
Fig3: Retinal vessel looked normal on OCTA scan, even when being zoomed in.
Fig4: Choriocapillaris slabs showed vessels pattern inside CO from different depth.
Fig5: Neovascularization was visualized in outer retina slab, which is an important complication of CO. Strong blood signal overlapped on B-scan confirmed the finding.
Fig6: Posterior boundary of choroid was detected accurately by algorithm.
Fig7: Choroid thickness map with volume values was automatically generated.
Fig8: Color fundus image and FFA from other devices for references.
Fig1-7 were captured and analyzed by a 400KHz swept source OCT/OCTA system (BMizar BM-400K, TowardPi Medical Technology)
