Filter by:The objective of the MERITAGE Trial is to evaluate the safety and efficacy of focal delivery of radiation for the treatment of subfoveal choroidal neovascularization (CNV) associated with wet age-related macular degeneration (AMD) in patients that require persistent injections of Anti-VEGF therapy to maintain an adequate response to treatment.
This study is a 5-year extension of the AREDS protocol, in which investigators followed the natural course of age-related macular degeneration (AMD) and cataracts. Participants in the former AREDS protocol are eligible for this study. Participants have a complete eye examination once a year and are contacted at least once a year between visits to check on their status. The eye examination includes measurement of visual acuity (vision chart test) and examination of the inside of the eye after the pupils have been dilated with eye drops. Photographs of the inside of the eye may be taken using a special camera that flashes a bright light in the eye. A blood sample may be obtained to test for cholesterol level and genes related to inflammation....
The purpose of the study is to evaluate the relative efficacy and safety of treatment of neovascular AMD with Lucentis on a fixed schedule, Avastin on a fixed schedule, Lucentis on a variable schedule, and Avastin on a variable schedule. A five year follow-up visit is being conducted in 2014 to gather information on long term outcomes.
The aim of the study is to show a higher expression of the Y402H polymorphism in the complement factor H in patients with AMD compared to healthy individuals. Additionaly a correlation between a subsided infection with chlamydia and patients with AMD and a factor H polymorphism will be investigated. An interrelationship with the VEGF-plasma level shall give more hints into the pathomechanism of AMD.
The purpose of this trial is to compare the ability of two doses of OT-551 ophthalmic solution and drug-free solution to safely and effectively treat geographic atrophy associated with age-related macular degeneration.
The objective of the CABERNET Trial is to evaluate the safety and efficacy of focal delivery of radiation for the treatment of subfoveal choroidal neovascularization (CNV) associated with wet age-related macular degeneration (AMD). The Epi-Rad90™ Ophthalmic System treats neovascularization of retinal tissue by means of a focal, directional delivery of radiation to the target tissues in the retina. Using standard vitreoretinal surgical techniques, the sealed radiation source is placed temporarily over the retinal lesion by means of a handheld medical device.
Age-related macular degeneration is one of the major causes of blindness in the western world. There is an exsudative and a non-exsudative form of age-related macular degeneration.Most studies concentrate on the exsudative form. In the non-exsudative form the policy is generally watch and see, but patients are at risk to develop an exsudative form. So far, the only accepted therapy to reach stable disease in the non-exsudative form is high-dose supplementation of antioxidants. Another approach to improve visual acuity in patients with non-exsudative form of macular degeneration is rheohemapheresis treatment, an extracorporeal therapy where plasma is separated from blood cells. By the use of a hollow fiber filter plasma is depleted of high molecular weight proteins and reinfused. Others report describe the supplementation of lutein (a vitamin A derivative) as possible treatment option. However, none of the studies have yet examined a combination of rheohemapheresis and lutein supplementation.
In this prospective clinical study SRT is performed with various pulse durations at 1.7µs and additionally 200ns to evaluate the different clinical effects of both laser regimens. The macular diseases to be treated are drusen maculopathy and geographic atrophy due to age-related macular degeneration as well as diabetic macular edema and central serous chorioretinopathy. The beneficial effect in laser treatment is thought to be associated with the restoration of a new barrier of retinal pigment epithelium cells. If this theory is true, the destruction of the photoreceptors causing visual field defects would be only an unwanted and unnecessary side effect. Thus, SRT is able to avoid these unintentional side effects and to achieve the benefit by just treating the RPE. In this study the clinical effect of SRT for these diseases is evaluated on a long-term basis.
The purpose of these studies are to evaluate the effect on vision in subjects with AMD who received active and placebo treatment in the MIRA-1 study.
To compare the efficacy and safety results of intravitreal bevacizumab alone with bevacizumab + triamcinolone acetonide in neovascular AMD.
