a Comparison between the controls and the POAG groups by using the Mann–Whitney U test for continuous data. The * and ** correspond to the significance levels at 5% (p < 0.05) and 1% (p < 0.01), respectively. N, number of participants; SD, standard deviation; POAG, primary open-angle glaucoma; CRAE, central retinal artery equivalent; CRVE, central retinal vein equivalent; BAP, biological antioxidant potential; dROM, Diacron reactive oxygen metabolites; SH, sulfhydryl.
