Filter by:It is a comparative study of Safety and Efficacy of Three Variants of Canaloplasty: ab-externo, ab-interno and minicanaloplasty. Combined With Phacoemulsification to Treat Glaucoma and Cataract. It is a Randomised, Prospective Study.
The purpose of this study is to assess how surgical interventions in glaucoma affect 24-hour intraocular pressure, 24-hour ocular perfusion pressure, optic nerve blood flow, and retinal oxygen saturation.
To evaluate effect of Netarsudil Ophthalmic Solution 0.02% on Nocturnal and Diurnal Intraocular Pressure.
The study objective was to evaluate the intraocular pressure (IOP) lowering effect of two iStent devices in eyes of subjects with primary open-angle glaucoma, washed out of two anti-glaucoma medications (one a Prostaglandin) prior to stent implantation.
The purpose of this study is to investigate the effect of trabeculectomy, glaucoma drainage devices, cyclophotocoagulation and ocular hypotensive eye-drops on IOP elevation with postural change from the sitting to supine positions in eyes with open-angle glaucoma. Patients will be assigned to the different study groups according to their past ocular history. Interventions are similar to all study group and no medical therapy alteration will be made.
This study objective is to evaluate the intraocular pressure (IOP) lowering effect of two trabecular micro-bypass stents (iStent inject) in eyes of subjects with primary open-angle glaucoma on one topical hypotensive medication
The objective of this study is to evaluate the long-term efficacy and safety of COMBIGAN® (brimonidine tartrate/timolol malate) in patients only using COMBIGAN® (brimonidine tartrate/timolol malate) and also in patients who require additional IOP lowering with LUMIGAN® (bimatoprost) 0.01%.
Globally primary open angle glaucoma (POAG) affects over 60 million people. The exact pathogenesis of POAG is poorly understood. A significant risk factor for glaucoma is advancing age. The rate of ageing is not the same in all age matched individuals. The concept of accelerated ageing suggests that the presence of a number of specific genetic, environmental or systemic risk factors may cumulate to accelerate the ageing process in some individuals and lead to the development of age-related disease. Understanding the factors that influence accelerated ageing is vital. Advanced glycation end products (AGEs) are a complex group of compounds that are naturally formed. They accumulate gradually with age in cells, tissues and blood vessels throughout the body where they adversely affect structure and function. Circulating AGE levels can be influenced by oxidative stress levels and dietary intake. Recent research has found that sustained exposure to high levels of circulating AGEs could be a major factor in the development of a number of chronic age-related degenerative disorders, including POAG. To date there have been few clinical studies that have been able to non-invasively explore the association between AGE levels and the development and progression of glaucomatous optic neuropathy (GON), or to explore the possible contribution that oxidative stress and dietary intake make to total tissue AGE levels in such patients. Furthermore little is understood about the relationship between AGE levels and retinal vascular function, a parameter known to be altered in GON that also could be influenced by AGE levels. The proposed study will aim to evaluate whether tissue-bound AGE levels are associated with parameters of retinal vascular function, oxidative stress, dietary intake and the presence of GON. Establishing this association could increase our understanding of the pathogenesis of GON and allow a new biomarker for accelerated ocular ageing to be realised
The purpose of this study is to evaluate whether the TUG device is safe and effective in patients with primary open angle glaucoma or ocular hypertension.
Phase II, randomized, double-masked study to evaluate the efficacy and tolerability of topical ocular delivery of fixed-dosed combinations of trabodenoson and latanoprost in subjects with Ocular Hypertension or Primary Open-Angle Glaucoma. All subjects who meet the study's enrollment criteria following Screening will undergo washout of all prohibited medications (if washout is needed), including their routine glaucoma medications. During the Placebo Run-In Period, placebo is applied twice daily to both eyes in all subjects. During the Treatment Period, study drug is applied to both eyes for a total of 8 weeks. Each subject will be assigned 4 weeks of AM and 4 weeks of PM dosing in a masked manner. AM vs PM dosing is masked utilizing Placebo in addition to the active drug product. During the Treatment Period, study drug (Active and Placebo) eye drop applications will occur twice daily, in the morning and in the evening. The Treatment Period will be followed by an Observation Period of approximately 7 days wherein no study eye drops are instilled. The purpose of the study is to assess the overall benefit/risk profile of binocular topical application of different doses of trabodenoson (3.0% and 6.0%) when combined with latanoprost (0.005% or 0.0025%) one drop daily (QD) for 8 weeks.
