OBJECTIVES To investigate the correlation and agreement between the intraocular pressure peaks detected during the water drinking test and the modified diurnal tension curve in untreated glaucomatous eyes. INTRODUCTION It has been suggested that the intraocular pressure peaks detected during the water drinking test predict the peaks observed during a 24-hour diurnal tension curve. A more feas...

OBJECTIVE To investigate the correlation between central corneal thickness and outflow facility assessed by intraocular pressure peak and fluctuation during the water drinking test. METHODS Fifty-five newly diagnosed primary open-angle glaucoma patients submitted to central corneal thickness measurements and water drinking test were enrolled in this retrospective study.;. Patients were divide...

PURPOSE To measure the tissue pressure gradient through the optic disk and to determine the relationship between intraocular, cerebrospinal fluid, and retrolaminar tissue pressures. The relationship of optic nerve subarachnoid space pressure to intracranial cerebrospinal fluid pressure also was explored. METHODS Micropipettes coupled to a pressure transducer were passed through pars plana and...

The parallel, randomized, double-masked, activecontrolled trial is generally thought to be the most rigorous and unbiased design to adequately compare two glaucoma medicines. Important to this design is the intraocular pressure entry criteria. The lower limit of intraocular pressure is usually set at least >21 mmHg to help assure the study population has the appropriate diagnosis (ocular hypert...

BACKGROUND We studied the effect of argon laser trabeculoplasty (ALT) on medically controlled, pressure-stable glaucoma patients to verify whether it is possible to reduce ocular hypotensive medication after ALT while keeping intraocular pressure levels similar to those observed before the procedure. METHODS Seventy-one consecutive chronic glaucoma patients, all of whom were taking ocular hyp...

PURPOSE To study the effects of filtration surgeries (tube and trabeculectomy) on changes in intraocular pressure after a water-drinking test. METHODS In this prospective, non-randomized, comparative clinical study, 30 patients who had tube surgery and 30 age- and sex-matched trabeculectomy patients underwent a water-drinking test. Only one eye of each patient was included. The baseline intra...

BACKGROUND To determine the agreement between intraocular pressure and the 'Wuerzburg bleb classification score', as well as between single items of the score and intraocular pressure. Interobserver variability was analyzed. METHODS 57 post-trabeculectomy eyes were included. Colour photographs were used to score the filtering bleb in accordance to the Wuerzburg bleb classification score by tw...

BACKGROUND The purpose of this study was to evaluate the precision of intraocular pressure measurements obtained by PT100 noncontact tonometry in a handheld and slit lamp-mounted position in comparison with that of Goldmann applanation tonometry in healthy young adults. METHODS Sixty eyes from 60 subjects (30 men and 30 women) aged 22 ± 1 (range 20-24) years participated in this study. Tripli...
