  1. IOP: intraocular pressure; MD: mean deviation; OCT: optical coherence tomography; RNFL: retinal nerve fiber layer; CDR: cup-disc ratio; VD: vessel density.
  2. *RNFL slope (μm/yr) = (Change in mean RNFL thickness during follow-up period) / (follow-up duration).
  3. Pearson correlation analysis was used.
