Filter by:The purpose of this study is to assess the comfort of a glaucoma therapy in patients with open-angle glaucoma or ocular hypertension
The purpose of this study is to evaluate the safety and efficacy of the iStent trabecular micro-bypass stent in reducing intraocular pressure (IOP) in subjects with newly diagnosed open-angle glaucoma and subjects diagnosed with Ocular hypertension.
The purpose of this study is to evaluate the safety and efficacy of the iStent trabecular micro-bypass stent in reducing intraocular pressure (IOP) in refractory open-angle glaucoma subjects.
To evaluate the safety and efficacy of a new trabecular bypass that is implanted in conjunction with cataract surgery in open angle glaucoma subjects.
The purpose of this study is to evaluate the safety and efficacy of the iStent trabecular micro-bypass stent in reducing intraocular pressure (IOP) in subjects with open-angle glaucoma or ocular hypertension and co-existing cataract.
The purpose of this study is to evaluate the safety, efficacy, and duration of effect of a single administration of Anecortave Acetate Depot for treatment of elevated intraocular pressure (IOP) in patients with open-angle glaucoma.
Low-pressure (normal tension) glaucoma is a type of open-angle glaucoma resulting in damage to the optic nerve and abnormalities of the visual field. Eye (intraocular) pressure in this type of glaucoma is not higher than that usually considered to be normal (less than 21 mmHg) for the eye. The present treatment of low-pressure glaucoma is also directed to lowering the “normal” eye pressure. Both medications in this study, brimonidine and timolol, lower eye pressure. Laboratory research over the past decade indicates the potential to treat glaucoma not only by lowering eye pressure, but with treatments aimed at the damage occurring at the optic nerve. One group of drugs, selective alpha2-adrenergic agonists, have been shown in laboratory animals to protect against the effects of nerve damage following local stroke. Brimonidine, one of the medications in the current study, is a selective alpha2-adrenergic agonist which protects against damage to optic nerve in animal models of glaucoma.. The hypothesis of the present study is that brimonidine eye drops provide protection to the damaged optic nerve independent of lowering eye pressure in patients with low-pressure glaucoma. This will be determined by (1) measuring eye pressure, (2) performing visual field examinations, and (3) examination of the optic nerve.
The purpose of this study is to determine whether a glaucoma therapy is safe and effective in treating patients with open-angle glaucoma or ocular hypertension.

Matrix metalloproteinases (MMPs) fulfill diverse important molecular functions and play pivotal roles in development, tissue morphogenesis, repair, aging, and inflammatory processes. MMPs are also important disease modulating factors, such as cancer, cardiovascular disease, rheumatoid arthritis or macular degeneration. Functional genetic variants have been described to fine-tune MMP activities at the gene transcriptional level and have been associated with increased genetic risk of e.g. arteriosclerosis or cancer. MMPs are also assumed to play a major role in the remodeling of the extracellular matrix (ECM) in the optic nerve head during glaucomatous optic neuropathy. MMP-1, MMP-3 and MMP-9 have been shown to be up-regulated in a variety of animal models of glaucoma. Here, we study three promoter SNPs within the genes encoding three members of the MMP family. By assessing the prevalence of genetic variants associated with either increased/decreased enzyme activity, we will (i) estimate their contribution to the genetic risk of developing primary open angle glaucoma (POAG) and (ii) investigate the potential role of MMPs in the functional pathology of POAG.
