Table 1.
Comparison of intraocular pressure (IOP) measurement obtained in different positions both with Icare PRO (ICP) and Tono-Pen AVIA (TPA), with evaluation of difference of IOP measurements between ICP and TPA in each position. CI 95% = 95% confidence interval from the mean; SD = standard deviation; Min/Max = minimum and maximum measurement. p value = level of significance obtained by Paired T-test. Δ= Difference between ICP and TPA. All IOP parameters were reported in mmHg.
