“…Recent studies have showed an established difference in IOP levels measured by DCT and GAT that varies between 0.8 and 4.9 mm Hg and exhibits, in most cases, statistically significantly higher IOP readings using the Pascal tonometer. [8][9][10][13][14][15][16][17][18][19][20][21][22][23]26,27 In the present study, DCT readings were a mean -SD of 4.3 -2.1 mm Hg higher than GAT readings (P < 0.0001), a difference that is comparable to those reported by other authors.…”

“…33 While investigating the effect of topical prostaglandine analogs on glaucoma and nonglaucoma subjects, Detorakis et al showed a higher DIOP in glaucoma patients treated with latanoprost in comparison to normal controls and glaucoma patients receiving other IOP-lowering medication, a finding that was attributed by the authors to possible induced alterations in the biomechanical properties of the ocular walls. 27 However, the study did not differentiate between different ocular hypotensive agents that focused mostly on the effect of latanoprost on DCT-GAT difference. In a recently published study, Wang et al investigated various factors that could affect the difference in IOP readings between DCT and GAT, reporting a positive correlation of DIOP to the axial length and a negative one to the corneal hysteresis.…”

“…Eleven studies 110,134,141,143,144,161,163,202,203,210,215 reported varying levels of correlation (from no correlation to a correlation coefficient of 0.46 in one study 141 ) and the other three studies 123,148,189 reported results directly relating to CCT subgroups. Martinez-de-la-Casa and colleagues 189 reported the mean IOP difference between DCT and GAT as 5.5 mmHg for patients in the lowest CCT tertile (≤ 530 µm), 4.2 mmHg for mid-range CCT and 3.5 mmHg for those in the highest CCT tertile (> 565 µm).…”

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...

“…Differences in the measurements of the intraocular pressure (IOP) by different tonometry methods, such as Goldmann Applanation Tonometry (GAT) and Dynamic Contour Tonometry (DCT), have been previously detected in glaucomatous eyes under treatment with latanoprost and have been used as indicators of the biomechanical behaviour of the eye [1, 2]. Perhaps the most important determinator of the latter is ocular rigidity, corresponding to the mathematical relationship between pressure and volume changes of the eye [3, 4].…”

Background. To evaluate differences between Goldmann Applanation Tonometry (GAT) and Dynamic Controur Tonometry (DCT) following trabeculectomy. Methods. Thirty eight glaucomatous eyes with a history of trabeculectomy (Trabeculectomy group, TG), 20 eyes without a history of trabeculectomy but with a history of latanoprost use (Latanoprost group, LG), and 19 nonglaucomatous eyes (Control group, CG) were included. GAT-IOP, DCT-IOP, the difference between them (dIOP), the central corneal thickness (CCT), the axial length (AL), and the depth of the anterior chamber (ACD) were measured. Results. dIOP was significantly higher in TG (5.19 mmHg) than in LG (4.01 mmHg) and CG (1.98 mmHg). Correlations between AL and dIOP were statistically significant in both TG and LG but not in CG whereas correlations between dIOP and other clinical parameters examined were statistically not significant in all groups. Conclusions. The significantly higher dIOP in TG implies that the bio-mechanical properties of the ocular walls are altered following trabeculectomy.

Applanation Tonometry Versus Dynamic Contour Tonometry in Eyes Treated With Latanoprost

Abstract: The fact that dIOP was significantly higher in LG, compared with NLG and CG implies that latanoprost may affect the biomechanical properties of the ocular walls.
