Filter by:Angioid streaks are rare lesions associated to retinal pigment epithelium degenerations. They can be caused by general diseases as pseudoxanthoma elasticum, Paget's disease or drepanocytosis. Choroidal neovascularization (CNV) represents the most frequent complication for those patients. It leads to a rapid and important loss of visual acuity. CNV in angioid streaks represent the fourth leading cause of CNV in young patients. CNV in angioid streaks is treated at the moment with off-label anti-VEGF (Vascular Endothelial Growth Factor) therapy and could also benefit from aflibercept (EYLEA), a new anti-VEGF currently indicated in AMD. Case reports suggest that such patients would not need as many injections as in AMD. ASTRID is an open-label, single arm, prospective, multicenter, phase II study. The main objective is to demonstrate the effectiveness in clinical terms after 52 weeks of treatment with aflibercept on the visual acuity of patients affected by CNV in angioid streaks. A specific dosage regimen is designed to achieve maximum efficiency. The patients are followed on a monthly basis until 52 weeks. Six injections are mandatory, the other ones are injected only in case of active CNV.
Study the effectiveness of the treatment detachment of retinal pigment epithelium secondary to polypoidal choroidal vasculopathy. Efficacy will be assessed by regression of polyp area after twelve months, compared to baseline. Treatment under study is a triple therapy with: 1) reduced-fluence photodynamic therapy (PDT), 2) intravitreal (IVT) triamcinolone and, 3) IVT ranibizumab, for the treatment of detachment of the retinal pigment epithelium (PED) secondary to Polypoidal Choroidal Vasculopathy (PCV).
The objective of this study is to confirm the safety and to establish the effectiveness of low voltage external beam radiosurgery using the IRay System for the treatment of subjects with recurrent leakage secondary to neovascular Age-related Macular Degeneration (AMD) as determined by decreasing the number of Lucentis injections required during the first 12 months of the study.
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.
Anti-VEGF therapy has been proven efficacious for the wet (neovascular) form of macular degeneration and may be beneficial for the treatment of choroidal neovascularization (CNV) due to other causes. The limitation of this type of treatment is the necessity for frequent intraocular injections. The purpose of this study is to determine if using anti-VEGF therapy in combination with photodynamic therapy can reduce the number of treatments needed with monotherapy while achieving similar visual results. There are ongoing multicenter trials evaluating combination therapy in patients with wet AMD but no similar trial for patients with CNV due to non-AMD causes. Therefore, in this study the investigators will focus on patients with CNV not due to AMD.
Intravitreal pegaptanib for treatment of choroidal neovascularisation secondary to pathologic myopia
The purpose of this study is to determine whether injections of ranibizumab into the eye are safe and well tolerated when given to subjects in multiple doses.
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.
The purpose of study is to determine if Lucentis combined with imatinib mesylate will help treatment in patients with newly diagnosed choroidal neovascularization.
