POAG: primary open angle glaucoma, SD: standard deviation, BVCA: best corrected visual acuity (decimal), MD: mean defect (dB), RNFL: retinal nerve fiber layer average thickness, IOP: intraocular pressure under medication (mmHg), CDR: cup-to-disc ratio. values were obtained with -test and posterior adjustment with FDR (false discovery rate).
