Percentage changes of circulatory parameters. Parafoveal blood flow velocity (pBFV, A), mean blur rate in the tissue area of the optic disc (MBRT, B), and retinal vessel diameters of artery (RVDA, C) and vein (RVDV, D) in eyes with primary open-angle glaucoma when compared with the baseline. Only the pBFV (A) significantly increased after topical tafluprost induction. *P shows statistical significance using a paired t-test adjusted by Bonferroni’s correction in measured values.
