  1. Data are given as mean ± standard deviation. SRCP = superficial retinal capillary plexus; DRCP = deep retinal capillary plexus; RPC = radial peripapillary capillary. *Statistically significant. Linear regression values adjusted for age and spherical equivalent. P Values were corrected by Bonferroni’s correction due to multiple testing.
