Advances have been made to develop techniques that can monitor IOP beyond the in-office measurements.
WebMean IOP in group 1 was 16.66 ± 6.59 mm Hg compared to the mean IOP of 14.72 ± 1.79 mm Hg in group 2 (Tab. 3). The mean IOP in groups was compared by an independent sample test. It was not statisti-cally significant (p-value = 0.048). Central corneal thickness was measured us-ing ultrasonic pachymetry in all patients in both groups. Web1 jan. 2002 · It would appear that large numbers of patients may have been misclassified based on their measured IOP. Many may not be treated as effectively as they could be. Those with OHT may be overtreated, a problem that could be avoided by physicians' performing pachymetry.
