Filter by:The purpose of this study is to develop an educational program that will help improve the patients' understanding of what laser treatment is, how it might be beneficial to them, and why it should be the first eye pressure lowering glaucoma treatment to consider before the use of glaucoma eye drops.
This study evaluates the efficacy and tolerability of a new formulation of latanoprost without Benzalkonium Chloride (BAK-free). Patients with open-angle glaucoma who were using BAK-containing latanoprost ophthalmic solution for ≥6 months, switched to BAK-free latanoprost ophthalmic emulsion.
This study evaluates the possible acute changes in peripapillary blood flow after instillation of antiglaucoma medications in patients with primary open angle glaucoma (POAG), normal tension glaucoma (NTG), or ocular hypertension (OHTN) using Optical Coherence Tomography (OCT) angiography.
The purpose of this study is to demonstrate that the rate of clinically relevant complications associated with CyPass Micro-Stent placement and stability using the CyPass 241-S applier, as determined at 36 months in the postmarket setting, is less than the pre-specified performance target, which is based on experience with the CyPass Model E applier in COMPASS trial TMI-09-01 (NCT01085357).
Aim: To demonstrate the non-inferiority of the PRO-122 ophthalmic solution manufactured by Laboratorios Sophia S.A. de C.V. versus Krytantek Ofteno® ophthalmic solution like hypotensive therapy in subjects with primary open angle glaucoma or ocular hypertension. Study design: a multicentric, prospective, crossover (2x2), double blind clinical study. Sample size: one hundred patients with primary open angle glaucoma or ocular hypertension. Patients in the period 1: In the first sequence 30 patients will be assigned to receive the ophthalmic solution: Krytantek Ofteno ® (timolol 0.5%%/brimonidine 0.2%/dorzolamide 2%) 1 drop B.I.D. during 30 days and the second sequence 30 patients will be assigned to receive the ophthalmic solution: PRO-122 1 drop B.I.D. during 30 days in the same period. Washout period: 20 hours. Patients in the period 2: the pharmacological intervention change to the opposite therapy for 30 days
The purpose of this study is to evaluate the clinical efficacy of the BREMEN eye drops in the treatment of primary open-angle glaucoma or intraocular hypertension.
Objectives: To evaluate the non-inferiority in the intraocular pressure decrease of the preservative-free ophthalmic solution PRO-122, manufactured by Laboratorios Sophia S.A. de C.V., versus concomitant therapy in subjects with uncontrolled primary open-angle glaucoma and/or IOP. Hypothesis: The mean (average) value of the IOP final absolute reduction in the experimental group (PRO-122) is not lower, considering a lower limit of 1 mmHg, compared to the IOP mean absolute reduction of the standard group (concomitant therapy). Methodology: A non-inferiority, phase III, double-blind, randomized, controlled, parallel, clinical trial
Some people with Primary Open-angle Glaucoma (POAG) also suffer from Obstructive Sleep Apnoea (OSA), a common sleep disorder which is known to affect heart and blood vessels, and may contribute to glaucoma progression. Obstructive Sleep Apnoea is treated with Continuous Positive Airway Pressure (CPAP); however using this type of breathing support may raise intraocular pressure (IOP). The evidence for this is limited and the potential mechanisms involved are poorly understood. In this study we will determine whether CPAP applied at night changes IOP and ocular perfusion pressure (OPP). We will also assess its possible impact on ocular microvasculature. Two groups of patients will be included: those with POAG and OSA, and those with OSA without glaucoma. They will attend for two overnight assessments: the first before starting CPAP and the second 4-6 weeks into the treatment. Repeated measurements of IOP at night will be performed and participants will continue self-measuring IOP at home in the day. An Ocular Coherence Tomography Angiography (OCT Angiography) of the optic disc and the surrounding retina will be performed at baseline and after a few weeks of CPAP treatment.
Lowering of the pressure in the eye (intraocular pressure, IOP) is the only proven treatment for Primary Open-angle Glaucoma (POAG). However, even effective reduction of IOP by pharmacological or surgical means does not always change the course of the disease or prevent the onset of glaucoma. Some people with POAG also suffer from Obstructive Sleep Apnoea (OSA), an increasingly common sleep disorder which is known to affect heart and blood vessels, and may contribute to glaucoma progression. OSA is treated with Continuous Positive Airway Pressure (CPAP); however using this type of breathing support may raise IOP. This study aims to establish whether a short-term application of CPAP in awake subjects leads to an increase in IOP. Patients with treated POAG, patients with newly diagnosed untreated POAG and control subjects without glaucoma will be included. CPAP will be applied at several different pressure levels for a total of 2 hours during which IOP and ocular perfusion pressure (OPP) will be measured. If CPAP is shown to raise IOP or alter OPP it could be necessary to assess available alternative treatment options for OSA.
The aim of this work is to evaluate efficacy and tolerability of preservative containing 0.0015% tafluprost and preservative-free 0.0015% tafluprost. Both preservative containing and preservative-free 0.0015% tafluprost will reduce intraocular pressure significantly. In addition, preservative-free 0.0015% tafluprost might improve tolerability of glaucoma patients.
