PURPOSE To determine the behavior of intraocular pressure and its relationship with infusion pressure in vitrectomy, phacofragmentation and phacoemulsification surgeries in rabbits. METHODS Intraocular pressure fluctuation was measured in 24 eyes of 12 rabbits submitted to vitrectomy, phacofragmentation and phacoemulsification procedures (eight eyes per group). The procedures were divided acc...

Objectives This study was designed to analyse the outcomes of secondary multifocal intraocular lens implantation in eyes with white cataracts. Methods White cataract patients undergoing secondary multifocal intraocular lens implantation between June 2014 and January 2015 were evaluated prospectively. As opposed to a conventional primary intraocular lens implantation for an optimal patient, th...

We examined the relationship of intraocular pressure and the development of one-kidney, one wrapped (perinephritic) hypertension in the dog. Conscious femoral arterial pressure (direct arterial puncture) and intraocular pressure (Schiotz tonometer) were measured weekly before and after the surgical induction of hypertension in 11 healthy male mongrel dogs and before and after unilateral nephrec...

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...

PURPOSE To report the results of a new technique for intraocular lens scleral fixation of temporary haptic externalization and four-point fixation for enhanced stability. METHODS Two 10-0 polypropylene strands were fixed at two points 2 mm apart on each haptic of a conventional three-piece intraocular lens, using our previously reported method of temporary haptic externalization after injecto...

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...
