FD, vascular fractal dimension in the inferior optic disc region; AT0.5–1.0PD, mean arterial tortuosity at 0.5–1.0 papillary diameter (PD) from the optic disc margin; VT, venous tortuosity; VCDR, vertical cup-to-disc ratio; ABA, mean arterial branching angle; VD1.0–1.5PD, vascular density at 1.0–1.5 PD from the optic disc margin; VD_fovea, vascular density within 5 mm of the fovea centralis; AD, arterial diameter; AD0.5–1.0PD, mean arterial diameter at 0.5–1.0 PD from the optic disc margin; MVD, mean venous diameter within 3 mm of the fovea centralis; AVR, arteriovenous diameter ratio; FTD, density of fundus tessellation. Data are presented as adjusted P-values. Between-group comparisons were performed using the Kruskal-Wallis test, followed by Bonferroni-corrected multiple pairwise comparisons.
indicates statistically significant difference (p < 0.05).
