Figure 1

Bland-Altman plots to demonstrate repeatability in measuring IOP (mmHg) between reading 1 and 2 with all devices (GAT a, ICP b and c and TPA d and e) and positions (sitting b and d and reclining c and e). Limits of agreement were provided as 1.96-times standard deviation with upper and lower limit of the differences. Units for both axes are mmHg. (GAT = Goldmann-Applanation-Tonometer, ICP = Icare PRO, TPA = Tono-Pen AVIA, SD = Standard deviation, S = sitting, R = reclining).
