Shi Y, Zhang Q, Zheng F, et al. - Researchers conducted this prospective, cross-sectional study to perform choriocapillaris (CC) imaging of normal eyes with swept-source optical coherence tomography SS-OCTA, as well as to compare the percentage of CC flow deficits (FD%) and the average area of CC flow deficits (FDa) within given macular regions. Using both 3x3 mm and 6x6 mm macular scan patterns, individuals with normal eyes ranging in age from their 20s through their 80s were imaged with SS-OCTA. An earlier published and validated algorithm was used to generate the CC images. In total, 164 eyes have been analyzed. An excellent associations were discovered between FDa and FD% in regions from 3x3 mm and 6x6 mm scans when measuring CC FDs. In order to determine if one parameter is more helpful when studying diseased eyes, further studies are required.
