N2 - The structural reliability methods quantitatively treat the uncertainty of predicting the behaviour and properties of a structure given the uncertain properties of its geometry, materials, and the actions it is supposed to withstand. WebIntraobserver and interobserver reliability in measurements have been reported to be 1.5 +/- 1.96 mmHg and 1.79 +/- 2.41 mmHg, respectively (14). In other words, the accuracy of any individual IOP measurement may vary by 3 or more mmHg simply based on the reliability limitations of the instrument.
