  1. SD, standard deviation; VFD-1, patients with visual field damage in one eye; VFD-2, patients with visual field damage in both eyes; BCVA, best corrected visual acuity; β, beta coefficient; SE, standard error for beta coefficient; p-value for multivariate linear regression model including visual field damage groups, BCVA, age, previous treatment (treated versus untreated); *, p-values for VFD-1 and VFD-2 refer to the comparison between each group and VFD-0 (patients without visual field damage in any eye).
