Correlation coefficient (ρ) and p-values for each pair of groups, calculated by using Spearman’s correlation test. The * and ** correspond to the significance levels at 5% (p < 0.05) and 1% (p < 0.01), respectively. sBP, systolic blood pressure; dBP, diastolic blood pressure; BCVA, best-corrected visual acuity; IOP, intraocular pressure; CRAE, central retinal artery equivalent; CRVE, central retinal vein equivalent; BAP, biological antioxidant potential in serum; dROM, Diacron reactive oxygen metabolites; SH, sulfhydryl.
