“…The factors that contribute to fluctuations in IOP are diurnal variations, body posture, exercise, eye movement, Valsalva maneuver, and the consumption of various foods and/or drugs. 21 However, because all IOP measurements were completed within 1 or 2 hours, this potential effect may be very limited. Finally, due to financial limitations, agreement between the CST and other recently developed tonometers, such as the rebound tonometer, dynamic contour tonometer, and ocular response analyzer, was not evaluated in this study.…”

PURPOSE.To compare intraocular pressure (IOP) measurements obtained using the Topocon noncontact tonometer (NCT), the Goldmann applanation tonometer (GAT), and the Corvis ST (CST), a newly developed tonometer with features of visualization and measurement of the corneal deformation response to an air impulse. A secondary objective was to assess the agreement among the devices.METHODS. Fifty-nine participants, including glaucoma patients (36 cases) and control volunteers (23 cases), were enrolled. One eye was selected randomly for further study. IOP measurements were obtained with the CST, NCT, and GAT by two experienced clinicians. IOP values were compared. Intraobserver variability and interobserver variability were assessed by the coefficient of variation and intraclass correlation coefficient. Device agreement was calculated by BlandAltman analysis. RESULTS.Mean IOP for all examined eyes was 18.9 6 5.8 mm Hg for CST, 21.3 6 6.8 mm Hg for NCT, and 20.3 6 5.7 mm Hg for GAT. There was no statistically significant difference in IOP measurements among the tonometers except between the CST and NCT. Correlation analysis showed a high correlation between each pair of devices (all P < 0.001). The CST displayed the best intraobserver variability and interobserver variability. Bland-Altman analysis revealed a bias between CST and GAT, CST and NCT, and GAT and NCT of À1.3, À2.4, and À1.1 mm Hg, with 95% limits of agreement of À6.2 to 3.5 mm Hg, À10.1 to 5.2 mm Hg, and À8.3 to 6.2 mm Hg, respectively.CONCLUSIONS. The CST offers an alternative method for measuring IOP. IOP measurements taken with these devices may not be interchangeable. (Invest Ophthalmol Vis Sci. 2013; 54:659-665)

“…Glaucoma, a progressive degeneration of retinal ganglion cell axons and cell bodies, is one of the most common ocular diseases leading to visual impairment and blindness [1,2]. Although glaucoma is considered to be a complex genetic disease, increased intraocular pressure (IOP) is a critical risk factor (for excellent reviews, see Sultan et al 2009 andNassr et al 2009 [2,3]).…”

Despite a lack of understanding of the precise pathological mechanisms leading to glaucoma, many recent studies have given an insight into the underlying etiopathology [4][5][6][7][8][9][10].…”

“…12 Thus, effective once-daily IOP-lowering medications must have consistent efficacy throughout the day to reduce the risk of IOP spikes, which have been associated with the progression of glaucoma. 13 TRAV 0.004% has not only demonstrated significant reductions in IOP throughout a 24 hr period, but also it has shown superior late afternoon (4 pm and 6 pm) efficacy compared with that of latanoprost 0.005%.…”
