SBP, systolic blood pressure; DBP, diastolic blood pressure; BCVA, best-corrected visual acuity; CRT, central retinal thickness. ^†At baseline, CRT, DCP, and acircularity index were abnormally distributed (, respectively, in Shapiro–Wilk’s test). The Spearman correlation was used to examine correlations with other variables. Pearson correlations were analyzed for others. .
