Values are means ± standard deviations; GSPPG = glaucoma suspect/preperimetric glaucoma; PG = perimetric glaucoma; MR = manifest refraction; D = diopter; CCT = central corneal thickness; IOP = intraocular pressure, VF = visual field; MD = mean deviation; PSD = pattern standard deviation; CDR = cup-to-disc ratio by clinical ophthalmoscopy
