    Repeatability and Reproducibility of a Quantitative Assessment of the Retinal Vascular Network Fractal Dimension Measured With Swept-source Optical Coherence Tomography Angiography in Healthy Eyesv

    Background: To evaluate the repeatability and reproducibility of the retinal vascular network fractal dimension (FD) measured from swept-source optical coherence tomography angiography (SS-OCTA) images of healthy eyes. Methods: A cross-sectional study was undertaken with young healthy volunteers who had no reported cardiac risk factors or ocular disease history. For each participant, three SS-OCTA images (12×12 mm) were acquired using the Cirrus Plex Elite 9000 (Carl Zeiss Meditec AG, Jena, Germany) by two ophthalmologists. The data from one eye per participant were retained for analysis. Automated segmentation was obtained from both the superficial and deep capillary plexuses. Fractal box-counting analyses ...
