From: Repeatability of intraocular pressure measurements with Icare PRO rebound, Tono-Pen AVIA, and Goldmann tonometers in sitting and reclining positions

Figure 3

Bland-Altman plots to demonstrate differences in IOP (mmHg) between sitting and reclining positions within the two hand-held tonometers, Icare PRO (a) and Tono-Pen AVIA (b). 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. (ICP = Icare PRO, TPA = Tono-Pen AVIA, SD = Standard deviation, M = mean, S = sitting, R = reclining).
