“…To date, however, few studies have addressed this issue, 4,17,[25][26][27][28][29] and further, to our knowledge, no direct comparisons of variability between these methods within the same group have been reported. This study was thus designed to simultaneously evaluate and compare intraexaminer and interexaminer repeatability, and reproducibility for DCT, ORA, and GAT within the same group of subjects.…”

Comparison of the quality score of intraocular pressure and ocular pulse amplitude values measured by the Pascal dynamic contour tonometer

The Pascal dynamic contour tonometer (PDCT) is designed to measure intraocular pressure (IOP) largely independent of the corneal properties. It is equipped with a digital LCD screen that displays the IOP, the ocular pulse amplitude (OPA) and the quality score (Q) of the measurements [range 1 (excellent) to 5 (poor)]. The manufacturer has recommended discarding the IOP and OPA values of Q4 and Q5. The aim of our study was to assess if IOP and OPA measurements with Q3 are acceptable for clinical and research purposes. This is a prospective, observational study in which both patients with ocular hypertension or glaucoma and healthy subjects were enrolled; three consecutive PDCT IOP measurements were performed on all participants. Only patients and subjects with Q1, Q2 and Q3 recorded together were eligible. Only one eye per subject was considered for statistical analysis. The mean PDCT IOP and OPA were taken for statistical analyses. An ANOVA test for repeated measures was used to compare the differences between PDCT IOP and OPA Q1, Q2, and Q3 scores. A total of 87 subjects met the inclusion criteria. Mean PDCT (+/-SD) IOP were 17.5 +/- 3.4 mmHg for Q1, 17.6 +/- 3.3 mmHg for Q2 and 17.9 +/- 3.3 mmHg for Q3 (P > 0.05). Mean OPA Q1, Q2 and Q3 were 2.5 +/- 0.9, 2.5 +/- 1.0 and 2.5 +/- 1.0 mmHg, respectively, and were not statistically different. Based on these results, we concluded that the IOP and OPA values with Q1, Q2 or Q3 measured by PDCT are not significantly different and can therefore be taken into account indiscriminately for clinical and research purposes.

HTA NIHR Health Technology Assessment programmeThe Health Technology Assessment (HTA) programme, part of the National Institute for Health Research (NIHR), was set up in 1993. It produces high-quality research information on the effectiveness, costs and broader impact of health technologies for those who use, manage and provide care in the NHS. 'Health technologies' are broadly defined as all interventions used to promote health, prevent and treat disease, and improve rehabilitation and long-term care. The research findings from the HTA programme directly influence decision-making bodies such as the National Institute for Health and Clinical Excellence (NICE) and the National Screening Committee (NSC). HTA findings also help to improve the quality of clinical practice in the NHS indirectly in that they form a key component of the 'National Knowledge Service' . The HTA programme is needs led in that it fills gaps in the evidence needed by the NHS. There are three routes to the start of projects...

Is the PASCAL®-Tonometer Suitable for Measuring Intraocular Pressure in Clinical Routine? Long- and Short-Term Reproducibility of Dynamic Contour Tonometry

Abstract: Short- and long-term reproducibility of DCT is comparable to that of GAT. GAT is more affected by CCT than DCT, measuring higher IOPs in eyes with higher central corneal thickness.
