BPVR and intraocular pressure (IOP) variability during the follow-up period were calculated by dividing the respective standard deviation values by the mean values. Correlated non-fluctuating BP metrics (baseline, mean, maximum, and minimum BP) were combined using principal component analysis separately for systolic BP (SBP) and diastolic BP (DBP). The first principal component was included as a covariate.
