Figure 5.

Difference versus mean plot illustrating the comparison between IOP measurements taken with the iCare tonometer at the baseline position (CC) and at specified angular deviations. (a) iCare tonometer probe was displaced by an angle of 10 degrees nasally. (b) iCare tonometer probe was displaced by an angle of 5 degrees nasally. (c) iCare tonometer probe was displaced by an angle of 5 degrees temporally. (d) iCare tonometer probe was displaced by an angle of 10 degrees temporally. The solid line represents the mean bias, and the dashed lines represent the 95% limits of agreement with the dotted regression line displayed. Angular deviation of the probe showed no significant correlation with measures at CC, in either of the two nasal and temporal positions.
