To better understand the relationship of Schi0tz pressure determination (in the recumbent position) to Goldmann applanation pressure determinations (in the sitting position), we studied, the change in intraocular pressure that occurs when a person changes from a sitting position to lying on his back, utilizing applanation tonometry for both positions. The average pressure rise was 0.3 mm. Hg in...

SIGNIFICANCE This article shows that self-tonometry can provide robust measures of diurnal intraocular pressure (IOP) and also detect changes to IOP in response to treatment within a short period of monitoring. These advances in IOP monitoring may contribute to improved management of glaucoma patients and suspects. PURPOSE The aim of this study was to prospectively investigate the utility of ...

OBJECTIVE To compare the dependence of dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT) on central corneal thickness (CCT) in primary open-angle glaucoma. METHODS In a prospective study, the interocular (right vs left eye) difference in intraocular pressure measured by DCT and GAT was compared with the interocular CCT difference in 125 patients with primary open-angle ...

Introduction: The study aimed to assert the relationship between central corneal thickness (CCT) and intraocular pressure (IOP) measured by: Goldmann applanation tonometry (GAT) Dynamic contour (DCT). Materials Methods: included 150 patients with a mean age of 59.39 ± 13.12 years. Patients were divided into three groups: 50 primary open-angle glaucoma (POAG) patients, ocular hypertension (OHT) ...

If glaucoma is diagnosed early, treatment can then be given that may preserve vision. Although raised intraocular pressure (IOP) is not the only sign of glaucoma, the IOP should be checked routinely on all adults attending eye care facilities. Applanation tonometry (as described in Issue 64, December 2007) is the most accurate method to measure IOP, but Schiötz tonometry is also a useful screen...
