Figure 3.

Scatterplot showing the association between the central corneal thickness and the difference in intraocular pressure measured by the Goldmann applanation tonometer and the PASCAL dynamic contour tonometer. There is a linear positive trend with difference in intraocular pressure being negative in eyes with lower-than-average central corneal thickness and positive with higher-than-average central corneal thickness. This indicates that the difference in intraocular pressure may be accounted in part by central corneal thickness.
