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 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...

AIMS To evaluate the intraocular pressure (IOP) measurements in patients with band keratopathy or glued corneas obtained from affected and non-affected areas. METHODS 15 patients with band keratopathy or glued corneas were prospectively recruited. When both eyes were affected, only the right eye was analysed. Tono-Pen readings of IOP were obtained sequentially from the affected and non-affect...

PURPOSE (a) To investigate whether the ICare rebound tonometer can provide accurate measurements of intraocular pressure (IOP) in the hands of an inexperienced user compared with ICare measurements and Goldmann tonometry by a trained technician and (b) to assess the intrauser reproducibility of IOP measurements and the learning curve among patients using the ICare rebound tonometer. METHODS A...

Modification of a standard Goldmann goniolens by reducing the curvature of the contact surface to 8.5 mm radius of curvature (from the standard curvature of 7.4 mm) enabled gonioscopy to be carried out without the nuisance of air bubbles.

purpose: to compare intraocular pressure (iop) measurement with pulsair non-contact tonometer and goldmann applanation tonometer (gat). methods: in this cross-sectional study, during a complete ophthalmologic examination, each patient underwent pulsair tonometry three times at 5 minutes intervals and then goldmann tonometry at the same intervals. mean iop values were measured and analyzed. resu...

Intraocular pressure (IOP) is the only known modifiable risk factor for glaucoma. Besides being a cornerstone in glaucoma management, accurate measurement of IOP forms an important component of routine ophthalmic evaluation. Despite the innovation of various newer tonometers, Goldmann applanation tonometer is still considered the Gold standard for IOP measurement. However, there are several rep...

BACKGROUND An accurate assessment of Intraocular pressure (IOP) is vital in establishing diagnosis of Glaucoma and decision making regarding various treatment modalities available. The purpose of this study is to compare Goldmann Applanation Tonometer (GAT) with Air puff tonometer. METHODS Cross-sectional comparative study conducted. 73 eyes from 73 patients were included in this study and in...

AIM To evaluate the reliability of the pressure phosphene tonometer in comparison with the Goldmann applanation tonometer. METHODS 45 consecutive patients with glaucoma (78 eyes) participated in the study. Eyes with previous eye surgery, a documented peripheral visual field defect, a refractive error of more than 5 dioptres, and patients who were unable to understand the procedure were exclud...
