To determine the prevalence of ocular surface disease (OSD) in patients with glaucoma using topical intraocular pressure (IOP)-lowering therapy.This prospective observational study enrolled primary open-angle or hypertension who were on a IOP-lowering medication regimen. Enrolled completed index (OSDI) and OSDI scores (0-100, 0 representing no symptoms) calculated for each patient. Medical history, demographics, concomitant information also collected.Overall, 630 from 10 sites participated....

Purpose: To evaluate the effect of 24-h peak intraocular pressure (IOP) on progression primary open-angle glaucoma (POAG) and 24 h time points that best predict pressure. Methods: A retrospective analysis clinical data evaluating long-term glaucomatous in patients with POAG who were previously a study authors (IOP readings at 2/6/10 A.M. PM); had ≥3 treated 10 (±1 h) IOP measurements over 5-years after an untreated baseline; curve IOP±2 mmHg within mean 5-years. Results: We included 98...

* BACKGROUND AND OBJECTIVE: The presentation and initial response to treatment of consecutive patients with exfoliation glaucoma (PXE) primary open-angle (POAG) were evaluated prospectively. PATIENTS METHODS: Forty-six newly diagnosed POAG PXE included in a prospective study that the clinical course results. two groups age- race-matched. RESULTS: This found no difference optic disc parameters at between (n = 22) those 24) (P > .05). However, presenting mean defect was significantly worse...

Microinjections of the cholinesterase inhibitor sarin were used to explore pons and medulla rabbit. Bilateral injections into lateral reticular nucleus at level inferior fovea caused respiratory arrest. Respiration was quickly restored after atropine given i.v. Other effects observed, reversed by atropine, included acceleration rate, bradycardia hypotension. The results are interpreted as indicating location a nervous center concerned with control muscles, which is site central paralysis in...

The optical and electrical switching characteristics of a lead zirconate titanate ferroelectric ceramic 'with Bi or La doping were studied for possible application in high speed light valve array. Of particular interest the requirements coincident voltage selection stable operation at least 1010 cycles. Excitation aging was found to decrease contrast achievable when is used as an electrically controlled retarder. A more pronounced result large increase degree partial caused by half-select...

To evaluate intraocular pressure (IOP) control over 24 hours using travoprost and timolol fixed combination (TTFC) administered in the morning or evening primary open-angle exfoliative glaucoma.Patients were randomized to TTFC either for 8 weeks. Previously treated patients underwent an untreated washout period of 4-6 weeks, after which baseline IOP was required be > 25 mm Hg < 38 mmHg (in two readings taken at 10.00 +/- 1 hours). During treatment period, measured 10.00, 14.00, 18.00, 22.00,...

Abstract. Purpose: To evaluate the efficacy and safety of timolol maleate/latanoprost fixed combination (TLFC) given once each evening versus brimonidine solution twice daily as concomitant therapy in primary open‐angle glaucoma or ocular hypertension patients. Methods: Qualified subjects were begun on alone for 1 month then randomized to either TLFC 6 weeks. Patients switched other treatment regimen. Intraocular pressures (IOPs) measured every 2 hours between 08 : 00 20 at baseline end...
