PURPOSE To compare intraocular pressure (IOP) measurements of the Ocular Blood Flow (OBF) pneumotonometer, Goldmann applanation tonometer, and Tono-Pen in eyes with normal corneas of various thicknesses. METHODS IOP was measured with an OBF pneumotonometer, Tono-Pen and Goldmann applanation tonometer in random order in 181 eyes with normal corneas. Central corneal thickness (CCT) was measured...

PURPOSE This study was designed to determine the relationship between central corneal thickness (CCT) and intraocular pressure (IOP) measured by applanation tonometer in glaucomatous, ocular hypertensive, and normal eyes. METHODS A total of 125 subjects were included in the study. Twenty-six had primary open angle glaucoma (POAG), 25 had pseudoexfoliative glaucoma (PXG), 24 had ocular hyperte...

OBJECTIVES This study aimed to compare intraocular pressure (IOP) measurements in healthy pediatric patients using three types of tonometers. MATERIALS AND METHODS Seventy-eight eyes of 78 patients under the age of 18 who underwent a routine ophthalmologic examination were included in the study. IOP was measured using Tono-Pen (TP) tonometry, Goldmann applanation tonometry (GAT), and non-cont...

Objective: The purpose of this preliminary study was to compare differences in the measurement of intraocular pressure (IOP) between TonoPen tonometry and Goldmann applanation tonometry (GAT) in healthy individuals and those with coexisting illnesses. Patients and Methods: This prospective study included 42 individuals who were further categorized into two groups. Group 1 consisted of 20 health...

The purpose of this study was to investigate whether measures derived from the SphygmoCor device and its associated transfer function are influenced by exercise-induced alterations in vascular tone. Measurements were taken from either the exercised or the contralateral nonexercised limb during repeated and identical incremental hand-grip protocols. Eight male subjects performed three 3-min bout...

AIM To evaluate whether intraocular pressure (IOP) calculation by applanation tonometry is determined more essentially by the subject's neck position or by neck constriction. METHODS 23 right eyes of 23 healthy subjects (12 male, 11 female) were included. IOP was measured by applanation tonometry with the TonoPen on sitting participants under four different conditions: with open collar uprigh...

purpose: to determine the distribution of intraocular pressure (iop), central corneal thickness (cct), and vertical cup-to-disc ratio (vcdr) in a healthy iranian population. methods: this cross-sectional, epidemiologic study (yazd eye study, yes) was performed on iranian adults, aged 40 to 80 years, residing in yazd, iran between 2010 and 2011. eligible subjects were selected using cluster rand...

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 evaluate the influence of anatomical and biomechanical properties of the grafts on the iop measurements methods : in this cross-sectional study conducted on 45 kera...

BACKGROUND The purpose of this study was to determine any difference in dynamic contour tonometry and ocular pulse amplitude in asymmetric glaucoma patients with the same applanation intraocular pressure. METHODS This is a prospective, observational study of 30 glaucoma patients and 11 controls from June 2007 to February 2008. Most of the glaucoma patients were on prostaglandin analog treatme...
