Active clinical trials for "Ocular Hypertension"

The study will evaluate patients diagnosed with POAG or OHT who are switched to GANFORT® UD (unit dose of fixed combination bimatoprost and timolol) therapy for medical reasons in accordance with physician standard clinical practice. All treatment decisions lie with the physician.

An observational study comparing changing from an IOP-lowering treatment to a bimatoprost-containing IOP treatment in primary open-angle glaucoma (POAG) or ocular hypertension (OHT). Visits and treatment are per normal clinical practice.

The main purpose of this prospective study is to demonstrate the therapeutic equivalence of topical brinzolamide compared with AzoptTM

This study will assess the efficacy, safety, tolerability and persistence of use of Lumigan ® 0.01% in patients diagnosed with primary open-angle glaucoma or ocular hypertension who are treated per routine clinical practice.

The Ocular Hypertension Treatment Study is a multi-center clinical trial sponsored by the National Eye Institute, designed to determine the efficacy and safety of topically administered eye lowering medication

Glaucoma is a chronic disease defined by characteristic changes in the optic nerve associated initially with loss of peripheral vision and is treated by lowering intraocular (inside the eye) pressure. It has been reported that noticeable changes to the optic nerve caused by glaucoma may occur several years before changes in vision are noticed. Since changes to the optic nerve and other eye structures due to glaucoma are irreversible, it is important to develop tools for the earliest possible detection of changes due to glaucoma. The Heidelberg Retina Tomograph (HRT) is a device that is used to produce a three-dimensional map of the optic nerve and retina, and can be used to detect changes in the optic nerve and retina over time. In previous studies, it has been shown to be useful for the detection of changes due to glaucoma. However, the HRT when compared to other techniques to evaluate the optic nerve such as stereophotography, was found to only somewhat agree. The current study will compare HRT to stereophotography to determine how good each one is at looking and documenting changes in the optic nerve over time due to glaucoma. Using HRT to initiate early topical medication or to change management requires knowing how well HRT results predict the development of visual loss. Accordingly, the results of this study may affect the management of glaucoma patients by optimizing the follow-up of people with this condition and by initiating appropriate and more individualized treatments. Early treatment is crucial for preventing further visual loss in patients with glaucoma or ocular hypertension (high pressure inside the eye).

Rhopressa effectively lowers intra-ocular pressure by improving conventional outflow and decreasing episcleral venous pressure. While this may result in improved episcleral venous flow, current methods to quantify episcleral blood flow in vivo are rudimentary and unable to accurately and precisely determine flow. Proof that Rhopressa effectively increases episcleral venous flow would differentiate it from other medications. Furthermore, this evidence could galvanize interest in the use of Rhopressa after popular Minimally Invasive Glaucoma Surgery (MIGS) procedures. In future studies, MIGS procedures could be used to improve the proximal outflow pathway, and Rhopressa to enhance distal outflow. Specific Aim: To determine the effect of Rhopressa on episcleral venous outflow and retinal blood flow in a cohort of treatment-naïve ocular hypertensive and glaucoma suspect patients. Hypothesis: Rhopressa increases episcleral venous flow and retinal blood flow from baseline at both 1 hour and 1 week after initiation of therapy.

This study evaluates the effect of dexamethasone implant which is an intraocular corticosteroid on the optic nerve fibers. Retinal nerve fiber thicknesses and optic nerve head pitting rates were measured before and 6 months after the injection.

Blindness can be caused by many ocular diseases, such as diabetic retinopathy, retinal vein occlusion, age-related macular degeneration, pathologic myopia and glaucoma. Without timely diagnosis and adequate medical intervention, the visual impairment can become a great burden on individuals as well as the society. It is estimated that China has 110 million patients under the attack of diabetes, 180 million patients with hypertension, 120 million patients suffering from high myopia and 200 million people over 60 years old, which suggest a huge population at the risk of blindness. Despite of this crisis in public health, our society has no more than 3,000 ophthalmologists majoring in fundus oculi disease currently. As most of them assembling in metropolitan cities, health system in this field is frail in primary hospitals. Owing to this unreasonable distribution of medical resources, providing medical service to hundreds of millions of potential patients threatened with blindness is almost impossible. To solve this problem, this software (MCS) was developed as a computer-aided diagnosis to help junior ophthalmologists to detect 13 major retina diseases from color fundus photographs. This study has been designed to validate the safety and efficiency of this device.

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
