Filter by:This randomized, controlled clinical trial will test the efficacy of Problem-Solving Treatment (PST) to improve vision function in older persons with age-related macular degeneration (AMD). AMD is a highly prevalent, disabling disease of aging that causes severe vision loss and functional decline. It is the leading cause of blindness in older persons in the United States and may affect more than 10 million people. Currently, there are no effective treatments to restore vision. Thus, improving Vision Function is a major goal of treatment. Vision function refers to vision-related abilities to perform daily living activities (e.g. reading recipes to prepare meals). Decrements in vision function will become a major public health problem as the population ages and the prevalence of AMD increases. PST is a brief, standardized, cognitive-behavioral treatment that teaches problem-solving skills. We believe PST will enable patients with AMD find practical solutions to vision-related problems and thereby improve vision function. We will recruit 240 AMD patients from the retina clinics of Wills Eye Institute, Philadelphia, PA, with bilateral AMD and visual acuity worse than 20/70 in the better eye. PST-trained therapists will deliver 6 1-hour, in-home sessions to the 120 subjects randomized to PST. The control treatment is Supportive Therapy (ST), a similarly structured, standardized psychological treatment that controls for the non-specific effects of treatment (n=120). ST contains no active elements beyond its non-specific components; in this way it is a placebo treatment. Independent raters, masked to treatment assignment, will assess Targeted Vision Function (primary outcome) and vision-related quality of life (secondary outcome) at 3 months to assess PST's efficacy, and at 6 months to evaluate its long-term effects. As the population ages, the disability of AMD will become more prevalent, costly, and burdensome to patients, families, and ophthalmologists. This makes devising and testing practical and affordable interventions to improve vision function a national priority.
The goal of this pilot study is to validate the use of the combination of Lucentis (ranibizumab) and Visudyne (verteporfin) in the treatment of choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) and to explore the use of a volumetric analysis of the CNV lesion to determine disease activity, response to therapy, and as a tool for determining the need for retreatment.
The treatment of fibrotic choroidal neovascular lesions with presence of residual peripheral activity in age related macular degeneration currently presents a great challenge. With visual loss threatening, there are only very few therapeutic options. While these patients are neither suitable for laser therapy nor for photodynamic therapy with Verteporfin, antiangiogenic drugs applied intravitreally are now available. Some patients however reject this therapeutic option because of potential complications such as endophthalmitis and the frequency of necessary injections. 20 patients who rejected intravitreal therapy were treated with Anecortave acetate (Retaane®) which was applied as a juxtascleral depot injection.
The objectives of this study are to evaluate the safety, tolerability, and pharmacokinetic profile of E10030 intravitreous injection when administered as monotherapy or in combination with Lucentis® 0.5 mg/eye in subjects with subfoveal choroidal neovascularization secondary to age-related macular degeneration (AMD).
The Cirrus OCT provides due to the spectral domain technology a 2-fold resolution than Stratus OCT generated in a comparable amount of time. Due to this higher resolution the retinal surface and the retinal pigment epithelium can be identified more clearly, a significantly reduced number of algorithm failures is expected
To evaluate if supplementation of zeaxanthin (with or without Lutein) is beneficial to patients with early and moderate Atrophic Age Related Macular Degeneration.
The study is designed to demonstrate the therapeutic non-inferiority of the recombinant humanized monoclonal VEGF antibody bevacizumab administered by intravitreal injection in the treatment of AMD in comparison to the related fragment ranibizumab.
This study will evaluate potential candidates for future clinical research studies related to diagnosed or undiagnosed genetic eye disorders or diseases. It will not test any new treatments, but it may arrange for standard treatments for existing eye disorders. The purpose of the study is to train eye doctors and medical researchers at the National Institutes of Health in appropriate methods and procedures for treating patients with genetic eye diseases, and to expand the pool of possible participants for future research studies and trials on eye health. Volunteers for this study may be adults and minor children who have been diagnosed with or are at risk for having a genetic eye disease. Candidates may not have any other medical conditions that would interfere with the researchers' ability to perform the examinations and procedures required for this study. Participants will give a complete medical and family history and undergo a series of tests and procedures as part of this research study. The procedures include a full eye examination and vision testing, electrooculography and an electroretinogram to examine the function of the retina, and flourescein angiography to provide information on the flow of blood in the participant's eyes. Participants will provide research material for further studies by giving a blood sample to be held for genetic testing and analysis, and adult participants will also undergo a skin biopsy to provide cell tissue for additional research material. At each clinic visit, participants will receive treatment for their genetic eye disease as needed, including medications or surgical procedures. Participants may remain a part of this study for up to three years.
The purpose of this study is to compare the safety and effectiveness of three doses of intravitreal bevasiranib sodium as maintenance therapy for Age-Related Macular Degeneration following initiation of anti-VEGF therapy with three doses of Lucentis®.
To report the short term anatomic and visual acuity response after intravitreal injection of bevacizumab (Avastin, Roche, Rio de Janeiro, Brazil) in patients with choroidal neovascularization secondary to age-related macular degeneration.
