Efficacy and safety of tafluprost 0.0015% and timolol maleate 0.5% fixed combination in patients with ocular hypertension or open-angle glaucoma.
2014
Lowering intraocular pressure (IOP) is at present the only therapeutic approach to the treatment of glaucoma proven to be successful. The choice of therapy must take into account efficacy, tolerability, safety, quality of life, adherence and cost. Monotherapy fails to achieve a satisfactory IOP reduction in 40 - 75% of glaucoma patients after2 years of therapy. So far, three prostaglandin/timolol maleate 0.5% fixed combinations (FCs) are available.This review provides a background on the tafluprost-timolol FC (TTFC, Santen Oy) and its individual compounds. It summarizes the data on efficacy and safety, including comparative data with prostaglandin/timolol FCs already available.Tafluprost is…
Steady-state levels of retinal 24S-hydroxycholesterol are maintained by glial cells intervention after elevation of intraocular pressure in the rat
2012
Purpose: Our previous studies suggested that CYP46A1 and 24S-hydroxycholesterol. (24SOH) may be associated with glaucoma. Loss of CYP46A1-expressing retinal. ganglion cells is involved in the activation of glia, and therefore possibly in the. disbalance of cholesterol. In this context, the purpose of our present work was to. emphasize the glial and longitudinal CYP46A1 expression after an interventional. glaucoma-related stress triggered by elevated intraocular pressure (IOP). Methods: Sprague–Dawley rats were submitted to laser photocoagulation of the. trabecular meshwork, limbus and episcleral veins in one eye to induce elevated IOP. Rats were euthanized at days 3, 14, 30 and 60 (n = 10 p…
Anaesthetic protocol for paediatric glaucoma examinations: the prospective EyeBIS Study protocol
2021
IntroductionNeonates and young infants with diagnosed or highly suspected glaucoma require an examination under anaesthesia to achieve accurate intraocular pressure (IOP) measurements, since crying or squinting of the eyes may increase IOP and lead to falsely high values. IOP considerably depends on perioperative variables such as haemodynamic factors, anaesthetics, depth of anaesthesia and airway management. The aim of this paper is to report the design and baseline characteristics of EyeBIS, which is a study to develop a standardised anaesthetic protocol for the measurement of IOP under anaesthesia in childhood glaucoma, by investigating the link between the magnitude of IOP and depth of …
Intercurrent factors associated with the development of open-angle glaucoma in The European Glaucoma Prevention Study
2007
Purpose: To evaluate the intercurrent factors for the development of open-angle glaucoma (OAG) in ocular hypertensive patients who were enrolled in the European Glaucoma Prevention Study (EGPS). Design: Randomized, double masked, controlled clinical trial. Methods: setting: Multicenter. study population: A total of 1,077 patients fulfilled a series of inclusion criteria, including intraocular pressure (IOP) 22 to 29 mm Hg, normal and reliable visual fields (VFs) and normal optic disks. intervention: Treatment with dorzolamide or placebo. main outcome measures: Glaucoma-related VF or optic disk changes. Clinical data were collected every six months during a five-year follow-up. Proportional …
Corneal Biomechanical Parameters and Central Corneal Thickness in Glaucoma Patients, Glaucoma Suspects, and a Healthy Population
2021
Purpose: To evaluate and compare corneal hysteresis (CH), corneal resistance factor (CRF), and central corneal thickness (CCT), measurements were taken between a healthy population (controls), patients diagnosed with glaucoma (DG), and glaucoma suspect patients due to ocular hypertension (OHT), family history of glaucoma (FHG), or glaucoma-like optic discs (GLD). Additionally, Goldmann-correlated intraocular pressure (IOPg) and corneal-compensated IOP (IOPcc) were compared between the different groups of patients. Methods: In this prospective analytical-observational study, a total of 1065 patients (one eye of each) were recruited to undergo Ocular Response Analyzer (ORA) testing, ultrasoun…
Addition of a fixed combination of brinzolamide 1%/timolol 0.5% to prostaglandin monotherapy in patients with glaucoma or ocular hypertension
2011
Katrin Lorenz1, Klaus Rosbach2, Andreas Matt3, Norbert Pfeiffer11University Medical Center, Johannes Gutenberg-Universität Mainz, Mainz, Germany; 2Private practice, Mainz, Germany; 3Private practice, Köln-Hohenhaus, GermanyBackground: This study was conducted to evaluate the safety and efficacy of adding a fixed combination of brinzolamide 1%/timolol 0.5% to prostaglandin analog (PGA) monotherapy in patients with primary open-angle glaucoma, pigment dispersion glaucoma, or ocular hypertension who require additional intraocular pressure (IOP) reduction.Methods: This was a prospective, multicenter (n = 5), open-label, single-arm, Phase IV clinical trial in which patients cur…
Effects of Fenoldopam on Intracranial Pressure and Hemodynamic Variables at Normal and Elevated Intracranial Pressure in Anesthetized Pigs
1994
Fenoldopam (FE), a dopamine DA1-receptor agonist, has been introduced for treatment of arterial hypertension and heart failure and for preservation of renal function. Vasodilators are generally assumed to affect all vascular beds including the cerebral circulation. We have evaluated effects of FE-induced (4 micrograms.kg-1.min-1) arterial hypotension on intracranial pressure (ICP) and intraocular pressure (IOP) under conditions of normal and increased intracranial elastance. ICP and IOP responses to hypertension were tested by infusion of angiotensin II (15 micrograms.kg-1.min-1), and the response to hypercapnia was tested by elimination and reintegration of soda lime canisters in the breat…
Meta-Analysis of Articles Evaluating Routine Intraocular Pressure Control in Monotherapy in the United States and Germany
2009
Pur P ose . To evaluate routine intraocular pressure (IOP) control in monotherapy patients in the United States and Germany. Methods . Meta-analysis of published articles. We included articles that were prospective studies of ocular hypotensive therapies that measured an unaltered (visit 1) IOP on monotherapy before enrolling into a clinical trial. results . This meta-analysis included 5 studies with 7913 patients, of whom 3245 were from the United States (n=1) and 4668 were from Germany (n=4). In the United States, 2939 patients (91%), and in Germany, 4059 patients (87%), had glaucoma (p<0.0001). Of these, all the US patients (100%) and 2694 (58%) of those from Germany were treated with mo…
The Heidelberg retina tomograph ancillary study to the European glaucoma prevention study: study design and baseline factors.
2013
Purpose: To describe the study design and baseline factors of the Heidelberg Retina Tomograph ancillary study within the EGPS. Furthermore, to examine the relationship between HRT optic disc topographic measurements and baseline demographic and ocular factors. Methods: Four hundred and eighty-nine ocular hypertensive participants were included. Each participant completed HRT imaging at least annually. The associations between HRT measurements and IOP, central corneal thickness (CCT), baseline photographic estimates of vertical CDR ratio (CDR), asymmetry between the two eyes in CDR ratio and baseline visual field indices were assessed using regression analysis. Results: Associations between …
