BACKGROUND Vision health is recognized as a critical unmet need in North America. The ocular morbidity associated with glaucoma results from increased intraocular pressure (IOP) and early detection is crucial for the management of glaucoma. Our objective was to find a diagnostically accurate screening tool for intraocular hypertension that can be used in rural communities. We sought to validate...

BACKGROUND Intraocular pressure (IOP) is the major known risk factor in glaucoma and the primer mover of the functional damage in glaucomatous patients but it is not a unique determinant of glaucomatous damage. Clinical assessment of glaucoma patients may not be a true reflection of overall IOP control. Evaluation of the effect of glaucoma medication is restricted by measurement of IOP as a dyn...

: This study was designed to evaluate and compare differences between Goldmann applanation tonometer’s (GAT) values non-contact (NCT) In various central corneal thickness(CCT). prospective of 100 eyes 50 subjects done for the age group 25 yrs – 75 yrs, who did not have any glaucomatous changes in optic disc. Intraocular pressure readings were taken by GAT NCT measured within a fixed time range ...

PURPOSE To determine the prevalence of calibration errors in Goldmann applanation tonometers at Farabi Eye Hospital. METHODS This cross-sectional study was performed on all tonometers in use at Farabi Eye Hospital. All Haag-Streit Goldmann applanation tonometers were checked according to the manufacturer's method by two independent observers and by a third observer in case of mismatched resul...

PURPOSE Post-Descemet stripping endothelial keratoplasty (DSEK) patients are prone for intraocular pressure (IOP) elevations and glaucoma. Corneal characteristics influence various IOP measuring devices in various ways. The aim of this study was to evaluate the agreement between four different IOP measuring devices: Goldmann applanation tonometer (GAT), I-care pro, Tonopen XL, and Schiotz tonom...

Purpose: This study investigates the intraocular pressures and dry eye signs before after botulinum toxin (botox) injections for patients with essential blepharospasm.Methods: From November 2021 to July 2022, a prospective examined 78 eyes of 39 diagnosed blepharospasm. Before injection 1 3 months injection, (IOPs) were measured using Goldmann applanation tonometer. The noninvasive breakup time...

Introduction: Cataracts and Glaucoma are the leading causes of irreversible blindness worldwide. Lens extraction using Phacoemulsification technique can be an effective IOP-lowering treatment for all types glaucoma.
 Objective: To study was to measure Intra-Ocular Pressure before after phacoemulsification determine mean change in Pressure.
 Methodology: This included 53 glaucoma patie...

Purpose To evaluate the effect of hemifacial spasm (HFS) on intraocular pressure (IOP) measurement. Methods Twenty-four consecutive patients with HFS and 25 age- and gender-matched randomly selected eyes of healthy volunteers underwent corneal pachymetry and IOP measurements using Goldmann applanation tonometer (GAT) and noncontact tonometer (NCT). IOP measurements were performed before (duri...

OBJECTIVE To compare the circadian intraocular pressure (IOP) reductions induced by latanoprost, brimonidine tartrate, and a fixed combination of timolol maleate and dorzolamide hydrochloride in patients with primary open-angle glaucoma (POAG) or ocular hypertension (OHT). METHODS In this crossover study, 10 patients with POAG and 10 with OHT were treated with latanoprost once a day, brimonid...
