Filter by:This research is being done to compare the safety and effectiveness of two sizes of the Baerveldt glaucoma implant. A Baerveldt glaucoma implant is one of the most common types of glaucoma operations performed. This procedure works by providing a route by which fluid can drain out of the eye to decrease the intraocular pressure. The Baerveldt implant does this by placing a tube into the eye which shunts aqueous fluid to a silicone plate which is attached to the sclera (white portion of the eye). It is this plate that comes in two different sizes (250 square millimeters and 350 square millimeters). Earlier studies have shown that larger plate sizes produce lower eye pressures but that they may also result in more complications. While both Baerveldt devices are currently in use and have been shown to be safe and effective, it is unclear if one is superior to the other. The purpose of this study is to see if one size of device works better with fewer complications.
This study will evaluate the safety and efficacy of new ophthalmic formulations of bimatoprost in patients with open angle glaucoma and ocular hypertension. At least 3 dose strengths will be evaluated based on internal data review of each cohort. The study was planned to be conducted in 2 stages. Stage 1 was an open-label and Stage 2 was planned to be masked; however only Stage 1 was conducted.
The purpose of this study is to assess the efficacy and safety of T2345 versus active comparator.
This phase IV study aims to assess the safety and the efficacy in intra ocular pressure of Geltim LP® 1 mg/g (0.1% unpreserved timolol maleate gel) in glaucomatous patients initially treated and stabilised by monotherapy of Xalatan® with ocular objective signs of intolerance to prostaglandin eye drops.
This study will evaluate the safety and efficacy of patients switched from latanoprost monotherapy to a combination therapy of latanoprost with COMBIGAN® (brimonidine 0.2%/timolol 0.5% fixed combination ophthalmic solution) for chronic angle closure glaucoma.
To determine the relationships between ocular hemodynamics and glaucomatous optic neuropathy progression.
To analyze Cosopt® in terms of its effects on ocular perfusion pressure and comprehensive ocular blood flow and in relation to visual field progression and optic nerve structural changes in an ongoing 3 year prospective study involving 120 patients with open angle glaucoma.
In cell cultures, lens epithelial cells and trabecular meshwork cells will be exposed to aqueous humor from pediatric eyes undergoing cataract removal surgery. Cytokine analysis of candidate factors will be performed before and after exposure to lens epithelial.
Primary congenital glaucoma patients and their immediate relatives will undergo complete ophthalmic examination and an interview with a geneticist. A blood sample will be drown from all participants for DNA analysis. The CYP1B1 gene coding sequences will be screened for all individuals. If no mutation or only one heterozygous mutation will be found in the CYP1B1 gene, screening for MYOC gene mutations will be performed.
The investigators aim to demonstrate the efficacy and safety of subconjunctival injection of Avastin as an adjunctive therapy for Ahmed valve glaucoma implant in patients with refractory glaucoma.
