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...

“…Troost et al [15] demonstrated that there was an increasing underestimation of the IOP by TGDc-01 tonometry compared with GAT with increasing IOP levels. They did not recommend the transpalpebral tonometry device, TGDc-01, as a substitute for GAT, at least when its use in patients with increased IOPs ≥20 mmHg was intended.…”

“…When the tip of the tonometer touched the eyelid, the measurement (falling of the rod) was automatically started [2]. In this study, GAT measurements were performed after installation of Alcain eye drops (Alcon Pharmaceuticals Inc., Puurs, Belgium) and positioning the scale of the tonometer at 10 mmHg [3,15,16].…”

“…Troost et al [7,10] demonstrated that there was an increasing underestimation of the IOP by TGDc-01 tonometry compared with the GAT with increasing IOP levels and concluded that the device may not be a substitute for the GAT, at least when its use in patients with increased IOPs ≥20 mm Hg was intended. They, however, recommended that TGDc-01 was a better choice for tonometry in patients with corneal pathology or in awake children than palpation of IOP, at least in normotensive subjects.…”

Comparative Evaluation of Diaton and Goldmann Applanation Tonometers

Aim: To evaluate the agreement between intra-ocular pressure (IOP) measurements with the Diaton and the Goldmann applanation tonometers (GAT). Methods: In this cross-sectional observational study, a total of 196 eyes of 196 participants (66 patients with glaucoma, 130 healthy subjects) were included. IOP measurements were obtained from all patients using the Diaton and GAT. Results: The average age of the patients enrolled in this study was 48.3 ± 14.6 years (range 18–79). The overall mean IOP measured by the Diaton was 17.2 ± 6.4 mm Hg, while that in glaucoma patients was 17.9 ± 6.2 mm Hg and in the control group 15.8 ± 4.9 mm Hg. Pearson’s correlation coefficient showed a moderate correlation in IOP measurements by the two instruments in healthy controls (r = 0.460, p < 0.01); however, the same correlation for the glaucomatous subjects was noted to be poor (r = 0.261, p = 0.57). The limits of agreement (95% confidence intervals) ranged from –9.9 to +11.2 and from –15.3 to +19.7 mm Hg in healthy controls and glaucoma patients, respectively. Conclusion: The Diaton measurements do not correlate well with those provided by applanation tonometry. The two tonometers show very wide limits of agreement so they may not be used interchangeably in clinical practice for the measurement of IOP.

Deviations between transpalpebral tonometry using TGDc-01 and Goldmann applanation tonometry depending on the IOP level

Abstract: TGDc-01-based tonometry demonstrated an increasing underestimation of IOP with increasing IOP levels when compared with the current standard method of Goldmann applanation tonometry.
