Shi Y, Zhang Q, Zheng F, et al. - In this prospective, cross-sectional study, choriocapillaris (CC) imaging of normal eyes with swept-source optical coherence tomographic angiography (SS-OCTA) has been conducted, as well as the percentage of CC flow deficits (FD%) and the average area of CC flow deficits (FDa) have been contrasted within the given macular regions. Using both 3×3-mm and 6×6-mm macular scan patterns, individuals with normal eyes ranging in age from their 20s through their 80s were imaged with SS-OCTA (PLEX Elite 9000; Carl Zeiss Meditec, Dublin, California, USA. Utilizing a previously published and validated algorithm, the CC images were generated. In total, 164 eyes have been analyzed. Excellent relationships were found between FDa and FD% in regions from 3×3-mm and 6×6-mm scans when measuring CC FDs. In order to determine if one parameter is more useful when studying diseased eyes, further studies are needed.
