  1. SVD superficial vessel defect, DVD deep vessel defect, IOP intraocular pressure, OCTA optical coherence tomography angiography, CCT central corneal thickness, MD mean deviation, PSD pattern standard deviation, VFI visual function index, RNFLT retinal nerve fiber layer thickness, CD cup to disc, GCIPLT ganglion cell inner plexiform layer thickness.
  2. Only variables with a P value < 0.10 in the univariate analysis were included in the multivariate model.
  3. Bold font indicates significant P values (P < 0.05).
