Filter by:This extension study will investigate the long-term safety and tolerability of multiple intravitreal injections of ranibizumab administered to patients with subfoveal choroidal neovascularization secondary to age-related macular degeneration who have been previously treated in either of the two ongoing ranibizumab studies CRFB002A2302 (EXCITE) or CRFB002A2303 (SUSTAIN
This study evaluates the tolerability and safety of a single intravenous infusion of ACZ885. It also explores the efficacy of the compound in central macular edema and visual acuity in patients with wet age-related macular edema.
CNV from AMD is the leading cause of blindness in people over 50 in North America. The hypothesis is to determine if there is an improvement in retinal function determined by ERG following treatment with ranibizumab for AMD
The purpose of this study is to compare the safety and effectiveness of bevasiranib given either every 8 weeks or every 12 weeks after an initial pre-treatment with 3 injections of Lucentis® (ranibizumab injection) compared to Lucentis® given every 4 weeks to people with wet AMD. Patients will be assigned at random (like tossing a coin) to receive one of three treatments options for 104 weeks.
In the industrialised world age-related macular degeneration (ARMD) is the leading cause for legal blindness beyond the age of 50 years. Recent studies indicate that the amount and status of the macular pigment (MP) may play a central role in the development and progression of the disease. It has been demonstrated that the MP density can be increased by dietary supplementation. First results of MP density measurements with a modified confocal laser scanning ophthalmoscope show that this method allows to quantify the MP in a clinical setting. The aim of this study is to assess the peak MP density as well as the MP distribution in relation to the risk for ARMD. We will establish reference values for MP density distribution in a normal population and compare these to values obtained from patients with age related maculopathy in a cross-sectional study. For all MP density measurements we will use a modified scanning laser ophthalmoscope and dietary intake of macular pigment will be assessed using a Food Frequency Questionnaire. Clinical examinations will include ETDRS visual acuity, binocular ophthalmoscopy, colour fundus photography and autofluorescence imaging. The results of our study will help assess the relationship of macular pigment density and distribution with ARMD. Additionally, we will be able to identify patients with low MP density, and probably improve the early diagnosis of patients at high risk for developing ARMD. This will be the basis for dietary supplementation of lutein and/or zeaxanthin in patients with high risk for ARMD due to low macular pigment values.
The objective of this study is to determine if combination therapy (reduced-fluence Visudyne followed by Lucentis [within 2 hours] or either of two regimens of reduced-fluence Visudyne followed by Lucentis-Dexamethasone triple therapy [within 2 hours]) reduces retreatment rates compared with Lucentis monotherapy while maintaining similar vision outcomes and an acceptable safety profile.
This study will test a new method for preventing worsening of age-related macular degeneration (AMD) and for developing imaging methods to follow the very earliest microscopic changes in the disease. The macula is the part of the retina in the back of the eye that determines central vision. AMD can impair central vision, affecting a person's ability to read, drive, and carry out daily activities. Some studies suggest that cumulative exposure to sunlight increases the risk for progression of AMD to the late stage that is often characterized by poor central vision. This study will determine if wearing glasses with a yellow filter over one eye and a red-violet filter over the other eye when outdoors will decrease the rate of change of early-stage AMD in one or both eyes. Patients early-stage AMD who have had cataract surgery in both eyes with implanted lenses may be eligible for this study. Participants undergo the following procedures: - Wear the filter glasses when outdoors between 10:00 a.m. and 4:00 p.m. - Record the time of day and light environment when they use the glasses. - Have an eye examination, pictures of the retina, and a medical history taken at the beginning of the study and at set intervals during the study. The study lasts at least 12 months and may be extended for a longer period of time....
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.
To evaluate the scotopic and photopic ERG responses before and after one month of intravitreal avastin injection in patients with choroidal neovascularization. A positive finding that will reveal a toxic effect of intravitreal avastin injection on any component of the retina will have a significant important clinical impact regarding the decision whether the benefit of avastin treatment for CNV will prevail over toxic effect.
The study will evaluate whether taking a nutritional supplement designed to increase macular pigment in the eye can improve a person's ability to adjust to darkness. Patients will be assigned to take either a placebo or nutritional supplement for 8 months. Vision will be assessed at baseline, 4 months, and 8 months.
