  1. NTG normal tension glaucoma, POAG primary open-angle glaucoma, IOP intraocular pressure; CCT central corneal thickness, OPP ocular perfusion pressure; SBP systolic blood pressure, DBP diastolic blood pressure, HR heart rate
  2. Data are expressed as mean ± standard deviation
  3. aKruskal-Wallis test; other parameters were analyzed using one-way analysis of variance
