Filter by:The FORESEE HOME is intended for the early detection of central and paracentral irregularities (abnormalities) in the visual field, most commonly associated with Age Related Macular Degeneration (AMD). However, the device has the ability to detect the development of the lesion post treatment and therefore to assess in determination of the next treatment. The Optical Coherence Tomography (OCT) may be used as well to identify choroidal neovascularization (CNV). Comparison between the two methods will allow better understanding of both devices. The FORESEE HOME can be used as an assessment tool for the progression and success of the treatment given to AMD lesions. Therefore, evaluating the size and the location of the treated lesions may serve as an additional tool.
This study will evaluate the safety and preliminary effectiveness of PDS 1.0 in patients with neovascular AMD.
Age related macular degeneration (AMD) is a multifactorial disease with a strong genetic component. Most importantly a genetic polymorphism in the gene encoding for the complement factor H (CFH) has been recently identified which is highly associated with an increased risk of developing AMD. This Tyr402His polymorphism located on chromosome 1q31 has been implicated to play a role in the development of the disease. For this purpose a total of 200 patients with wet AMD will be included in the study. As described in detail below, the current study aims to identify potentially non-responders to anti-VEGF therapy based on genetic analysis of VEGF polymorphism and complement factor H polymorphism.
Efalizumab is an immunosuppressive recombinant humanized IgG1 monocolonal antibody (150 Kd) that binds to human CD11a (1) and is used for the treatment of plaque psoriasis. Efalizumab was derived from the humanization of the murine efalizuman monoclonal antibody MHM24, which recognizes human and chimpanzee CD11a. Humanization of MHM24 was accomplished by grafting the murine complementarity determining regions (hypervariable region) into consensus human IgG1/ heavy and light chain sequences (Werther et al 1996). These same consensus human immunoglobulin sequences have been successfully used in the humanization of other murine antibodies, including those targeted to HER2 and IgE. Efalizumab inhibits the binding of LFA-1 to intercellular adhesion molecule-1 (ICAM-1) thereby inhibiting the adhesion of leukocytes to other cell types. Ranibizumab is a recombinant, humanized, Fab fragment of a mouse monoclonal antibody targeted against VEGF. As VEGF binds to cellular receptors, it stimulates angiogenesis and vascular leakage. Blockade of VEGF by ranibizumab leads to reduced stimulation of cell proliferation and permeability resulting in inhibition of angiogenesis and decreased leakage. Ranibizumab intravitreal administration in neovascular AMD patients has been shown to effectively reduce vascular leakage and growth of CNV and to stabilize or improve visual function. To further improve visual acuity, a combination therapy using efalizumab and ranibizumab is proposed. Efalizumab could target the adhesion factors that precede angiogenesis and improve the outcome for AMD patients in combination with the anti-VEGF agent, Ranibizumab.
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®.
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 study is to demonstrate that Visudyne-Lucentis-dexamethasone (V-L-D) triple therapy will give similar efficacy and safety results as Lucentis monotherapy.
The object of the study is to compare the treatment effect of bevacizumab (Avastin), an antibody targeting vascular endothelial growth factor, with verteporfin photodynamic therapy (PDT) for patients with neovascular age-related macular degeneration, the leading cause of vision severe loss in the Western world.
