The accuracy of diagnosing PG and PPG against the reference normal group was assessed by the area under the receiver operating curve.

Abbreviation: PPG = pre-perimetric glaucoma; PG = perimetric glaucoma; AROC= area under the receiver operating curve; SE = standard error. GCC = ganglion cell complex thickness; AVG = average; FLV (%) = focal loss volume expressed as a percentage of the average GCC volume in the normal group; GLV = global loss volume; PCV = pattern coefficient of variation; SID = superior - inferior difference; MR = macular retina thickness; NFL = nerve fiber layer thickness; FD-OCT: Fourier-domain optical coherence tomography; TD-OCT: time-domain optical coherence tomography

^*The AROC was not significantly better than 0.5 and was omitted.
