View clinical trials related to Age-Related Maculopathy.
Filter by: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.
In this pilot study the researchers will evaluate the safety and efficacy of 50% reduced fluence PDT combination therapy with ranibizumab. The researchers hope to gain information regarding the use of reduced fluence PDT combination therapy. The information gained from this pilot study may prompt further definitive studies comparing the safety and efficacy of both standard fluence PDT combination therapy, reduced fluence PDT combination therapy, and ranibizumab monotherapy. The study will compare the use of combination therapy with ranibizumab and verteporfin PDT to ranibizumab alone in patients with exudative age-related macular degeneration (AMD). All patients will receive three consecutive monthly treatments with ranibizumab. Patients will be randomized 1:1:1 to 3 groups. Patients randomized to group 1 will receive only ranibizumab. Patients randomized to group 2 will also receive one treatment with reduced fluence (50% fluence) verteporfin PDT at day 0. Patients randomized to group 3 will also receive one treatment with standard fluence verteporfin PDT. All patients will also be evaluated for possible retreatment with ranibizumab and verteporfin PDT according to established criteria. Thirty patients will be recruited from one U.S. sites. Randomization will occur at the time of entry into the study. Follow-up will continue until month 12 (from day 0) in all subjects.
The purpose of this study is to measure the effectiveness of a newly-designed oculomotor training program for patients with age-related macular degeneration.
The primary purpose of this study is to determine if injections of rhuFab V2 into the eye in combination with verteporfin photodynamic therapy (PDT) is a safe and efficacious treatment for patients with age-related macular degeneration.
The purpose of this study was to evaluate anecortave acetate compared to placebo for maintenance of visual acuity after 24 months of treatment in patients with subfovial choroidal neovascularization (CNV) due to exudative age-related macular degeneration (AMD).
