Figure 1 Schematic illustration of Ocular Response Analyzer signal with the 3 waveform parameters (blue line) associated with the mean of total deviation progression rate in multivariate analysis. Red lines indicate 25% base of applanation peaks. A, path2 is the length of path at 25% base around AP2. B, p2area is the area of AP2 at the 25% base. C, mslew2 is the maximum single length of the outside line segment (longest continuous line without a break) of AP2.

Figure 2 Schematic illustration of Ocular Response Analyzer waveform presumably disadvantageous to glaucomatous visual field progression, as suggested by the current analysis. The waveform shown in the dotted line is an unspecific one, whereas the waveform shown in the solid line reflects characteristics disadvantageous to glaucoma progression as suggested in the multivariate analysis: larger path2 and p2area.
