Figure 2

Bland-Altman plots to demonstrate differences in mean IOP (mmHg) between Goldmann-Applanation-Tonometer and the two hand-held devices separately for both positions (sitting and reclining), Icare PRO (a, b) and Tono-Pen AVIA (c, d). 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, M = mean, S = sitting, R = reclining).
