PURPOSE To present a prospective, nonrandomized study of intraocular pressure (IOP) after clear corneal phacoemulsification in eyes with pseudoexfoliation (PEX) syndrome. METHODS A PEX group of 39 consecutive open angle, nonglaucomatous eyes with cataract in PEX syndrome, and a control group of 40 consecutive open angle, nonglaucomatous eyes with cataract, were operated on by the same surgeon...

PURPOSE To determine the agreement between intraocular pressure (IOP) measurements using an automated non-contact tonometer (NCT), Goldmann applanation tonometer (GAT), and the ocular response analyzer (ORA) in subjects with primary congenital glaucoma (PCG). METHODS Twenty-nine eyes of 17 PCG patients underwent IOP measurements using NCT, GAT and ORA. Variables obtained by the ORA were corne...

Ocular sympathetic nerves were stimulated chronically in awake rabbits using electrodes unilaterally implanted on the cervical sympathetic trunk. IOP was measured by pneumatonometry and aqueous inflow was measured by fluorophotometry. In each animal, continuous trains of 1 msec pulses were delivered by means of a portable electrical stimulator. Experiments were spaced by 1 week recovery periods...

A recent study has reported an excellent correlation between intraocular pressure (IOP) and intracranial pressure (ICP), suggesting that measurement of IOP may serve as a noninvasive means to determine ICP. To reexamine the relation between IOP and ICP, we reviewed the medical records of all patients who underwent lumbar puncture between 1991 and 2007 in the neuro-ophthalmology clinic at the Un...

purpose : to compare the effectiveness and safety of trabeculectomy with mitomycin c (mmc) versus trabeculectomy with oculusgen methods : in this prospective study 14 eyes of 7 patients with a diagnosis of primary open angle glaucoma (poag) that required trabeculectomy for both eyes were enrolled. for each patient we randomly performed trabeculectomy with mmc for one eye and trabeculectomy with...

BACKGROUND Cataract surgery combined with excimer laser trabeculotomy (phaco-ELT) can reduce intraocular pressure (IOP). The aim of this study was to evaluate the effect of phaco-ELT on IOP in patients as a function of preoperative IOP. METHODS Patients with open-angle glacuoma or ocular hypertension who received phaco-ELT between 01/2008 and 10/2009 were included. Patients were assigned base...

PURPOSE To distinguish 24-hour (circadian) and postural effects on intraocular pressure (IOP) in healthy young adults. METHODS Thirty-three volunteers were housed in a sleep laboratory for 1 day under a strictly controlled 16-hour light and 8-hour dark environment. Sleep was encouraged in the dark period. Intraocular pressure was measured in each eye every 2 hours using a pneumatonometer. Res...

ReportofaCase.A29-year-oldwoman had retinitis pigmentosa with typical ophthalmoscopic findings, a ring scotoma, and a flat electroretinogram. Juvenile glaucoma was diagnosed at the age of 12 years. Becauseof thecharacteristicmalformation of the anterior segment it was classifiedasRiegersyndrome.Theinitial IOP at the time of glaucoma detection was 50 mm Hg. Both eyes underwentElliotoperation.The...

PURPOSE To determine the accuracy of visual estimation of immediate postoperative intraocular pressure (IOP) following microincision cataract surgery (MICS) and the effect of immediate postoperative IOP adjustment on prevention of cystoid macular edema (CME). SETTING Ambulatory surgical center. METHODS Prospective, randomized analysis of 170 eyes in 135 patients with MICS, performed in a Me...
