OBJECTIVE WE AIMED TO COMPARE INTRAOCULAR PRESSURE (IOP) MEASUREMENTS VIA THREE DIFFERENT TONOMETERS: the Goldmann applanation tonometer (GAT), the Tono-Pen(®) XL (TPXL), and a non-contact airpuff tonometer (NCT). METHODS This was a cross-sectional study of 200 eyes from 200 patients. Right eyes of all patients were included in this study. IOP was measured via GAT, NCT, and TPXL by three phys...

background: to evaluate the agreement in intraocular pressure (iop) measurements by ocular response analyzer (ora) and tono-pen xl (txl) with the goldmann applanation tonometer (gat) and to examine corneal biomechanical properties in aphakic glaucoma patients with a central corneal thickness (cct) >600 µ. methods: thirty-six eyes of aphakic glaucoma patients (group 1) and 40 eyes of normal chil...

purpose: to compare intraocular pressure (iop) readings measured by the ocular response analyzer (ora) with those measured by the goldmann applanation tonometer (gat) in keratoconic eyes following penetrating keratoplasty (pkp) and to evaluate the influence of anatomical and biomechanical properties of the grafts on iop measurements. methods: this cross-sectional study was conducted on 45 kerat...

PURPOSE To investigate the correlation coefficients between intraocular pressure (IOP) before and after adjusting for central corneal thickness (CCT) and corneal biomechanical properties. PATIENTS AND METHODS A total of 218 eyes of 218 patients with primary open-angle glaucoma (mean age =71.5 years; mean spherical equivalent =-0.51 D; mean deviation determined by Humphrey visual field analyze...

OBJECTIVE To evaluate the effect of central corneal thickness (CCT), corneal curvature, and axial length on applanation tonometry in an in vivo study. METHODS In a masked, prospective clinical trial, we examined 125 eyes of 125 patients scheduled for cataract surgery. Corneal curvature was measured by means of keratometry and axial length by A-scan ultrasonography. By cannulating the anterior...

The purpose of our study is to evaluate the effect of a single drop of latanoprost on the intraocular pressure and blood-aqueous barrier permeability in 8 patients with uveitis. The degree of inflammation was determined by the intensity of aqueous flare measured with a laser flare cell meter every 2 hours from 11:00 to 17:00 hours for 2 days. Intraocular pressure was measured at 11:00 and 17:00...

The present study investigated whether a correlation between days of the menstrual cycle and variations in intraocular pressure exists or not. The number of days since the beginning of last menses was recorded along with intraocular pressure for 1,459 women. Measurements were taken by Goldmann applanation tonometer. The differences among various days of menstrual cycle were statistically insign...

Background: Repeatability and validity are important components of precision in any measurement system. Aim: This study aimed to determine the effect change head neck position body posture on repeatability intraocular pressure (IOP) measurements with PT-100 non-contact tonometer compare Goldmann, Schiøtz readings. Setting: Optometry clinic, Saudi Arabia. Methods: The IOP was measured one select...
