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 ...

BACKGROUND/AIM Several factors may have influence on systemic circulation. Additionally, peripheral circulation also demonstrates sex differences, in young women presenting significantly lower finger blood flow in comparison to men of the same age, a finding that disappears in women after menopause. The aim of this study was to compare the retrobulbar hemodynamic parameters measured by means of...

INTRODUCTION The Pascal Dynamic Contour Tonometer (DCT) is an ophthalmic investigational device which directly calculates the dynamic pulsatile fluctuations in intraocular pressure (IOP) using a piezoelectric pressure sensor embedded in the devices tip. OBJECTIVE The aim of this study was to compare IOP results obtained with Goldmann applanation tonometer (GAT), and their correlation with cen...

PURPOSE To compare intraocular pressure (IOP) between the new non-contact tonometer Corvis ST (CST), the Goldmann applanation tonometry (GAT) and Icare Pro rebound tonometer (PRO). METHODS A total of 178 eyes of 178 healthy subjects were selected for the study. Measurements of IOP were made in a random order with GAT, PRO and CST. Central corneal thickness (CCT) was determined by ultrasound p...

PURPOSE To evaluate if using the Ehlers correction factor on the intraocular pressure (IOP) measured using the Goldmann applanation tonometer (GAT) improves its agreement with the PASCAL dynamic contour tonometer (DCT). PATIENTS AND METHODS A total of 120 eyes of 120 individuals were examined. Participants underwent IOP measurement with both the DCT and the GAT and central corneal thickness m...

PURPOSE To assess the intraocular pressure (IOP) and ocular rigidity (E) at 1, 3, 6 and 24 postoperative months in eyes that underwent LASIK. METHODS The IOP measured by Goldmann applanation tonometer (GAT) and by the 5.5 and 10 gm. weights of a standardized Schioetz tonometer (ST) and the E measured by differential tonometry (the 5.5 and 10 gm. of ST) were assessed before and after LASIK (at...

OBJECTIVE To measure the difference in intraocular pressure with use of two different types of eye speculums. METHODS The study was conducted at the Department of Ophthalmology, Abbasi Shaheed Hospital, Karachi, from November 2011 to May 2012. Through probability convenience sampling, hundred patients were selected and divided into two equal groups. Complete history and ocular examination was...

PURPOSE Rebound tonometry has recently been modified for its use in humans. The purpose of our study was to determine the precision of the ICare(R) rebound tonometer (RBT) as compared with the Goldmann applanation tonometer (GAT). METHODS Patients were recruited from our Hospital's Glaucoma Unit. In each patient, intraocular pressure (IOP) was measured without anaesthesia using the RBT and te...

PURPOSE To compare the intraocular pressure measurements as defined by the Pascal tonometer, the Goldmann tonometer and the pneumotonometer. METHODS This was an observational clinical study, which included two hundred and five randomly selected subjects recruited from the Ophthalmology Department. The intraocular pressure measurements were performed with each tonometry technique in a randomiz...

The applanation method is generally accepted as being the most accurate for measuring intraocular pressure. Perkins (i965) described a hand-held portable applanation tonometer. Whitty (I969) reported his results using this tonometer: he found that readings with the hand applanator were slightly (I-I-5 mm.Hg) lower than those taken with the Haag-Streit tonometer, and he felt that this may have b...
