Does Rebound Tonometry Probe Misalignment Modify Intraocular Pressure Measurements in Human Eyes?

Figure 2

Difference versus the mean plot illustrating the comparison between IOP measurements taken with GAT and iCare tonometer. The iCare tonometer significantly overestimated IOP compared to the GAT. The solid line represents the mean bias, and the dashed lines represent the 95% limits of agreement.
