      Optimizing the Repeatability of Choriocapillaris Flow Deficit Measurement from Optical Coherence Tomography Angiography

      Purpose To evaluate impact of processing technique and slab selection on the repeatability of choriocapillaris (CC) flow deficit (FD) measurements as assessed using optical coherence tomography angiography (OCTA) Design: prospective, cross-sectional study Methods Healthy subjects were imaged with four consecutive 3x3mm OCTA using a swept source OCT (PLEX elite 9000, Carl Zeiss Meditec, Dublin, CA). OCTA images were generated using the Max projection, and three 10 μm-thick slabs starting 11, 21 and 31 μm posterior to the automatically segmented retinal pigment epithelium (RPE) band. The resultant images were binarized using Phansalkar’s method with a 43.94 μm radius and ...

      Impact of slab selection on quantification of choriocapillaris flow deficits by optical coherence tomography angiography

      Purpose To assess the impact of slab selection on quantitative measurements of choriocapillaris (CC) flow deficits (FDs) using optical coherence tomography angiography (OCTA). Design Cross-sectional study Methods Using a swept-source OCTA device, en face slabs to isolate the CC were first generated using the manufacturer’s default setting: a 20 μm-thick slab starting 29 μm posterior to the centerline of the automatically segmented retinal pigment epithelium (RPE) band. The inner and or outer borders were then adjusted by 2 μm increments to generate CC slabs with a range of offsets relative to the center of the RPE band. FDs of ...
