Group mean ± standard deviation are shown. VF_MD = visual field mean deviation; NFLP_MD = retina nerve fiber layer plexus mean deviation (simulated visual field mean deviation); BCVA = best corrected visual acuity; logMAR = logarithm of minimum angle of resolution; PPG = pre-perimetric glaucoma; PG = perimetric glaucoma.
