Active clinical trials for "Multifocal Choroiditis"

The purpose of this study is to evaluate the safety and tolerability of intravitreal injections of ranibizumab in the treatment of AMD variants and other choroidal neovascularization (CNV) related conditions (Coats' disease, idiopathic perifoveal telangiectasia, retinal angiomatous proliferation, polypoidal vasculopathy, pseudoxanthoma elasticum, pathological myopia, multi-focal choroiditis, rubeosis iridis) using the incidence and severity of adverse events. Limited forms of treatment are available that limit the loss of visual acuity. However, the patients may not have any substantial improvement in acuity or function. Therefore there remains a significant unmet need for therapeutic options managing the neovascularization and its consequences. Lucentis (ranibizumab) injection will be considered as an attempt to control the growth of the abnormal vessels because of evidence suggesting that angiogenic factors, such as vascular endothelial growth factor (VEGF), play a role in the pathogenesis of neovascular non-AMD conditions. The rationale for the study design is as follows: A 0.5 mg dose of Lucentis (ranibizumab), a commercially available preparation that is Food and Drug Administration (FDA) approved and labeled for intravitreal injection use for neovascular (wet) age-related macular degeneration will be used. In AMD variants and other CNV related conditions, vascular endothelial growth factor (VEGF) plays a role in the pathogenesis as in neovascular AMD. Intravitreal injection of ranibizumab delivers maximal concentration of the antibody fragment to the vitreous cavity with minimal systemic exposure. The dosing schedule, based on considerations of the half-life and the clinical response in patients with neovascularization suggests that a 1-month interval is optimal.

Intravitreal injection of Bevacizumab in patients with Neovascular Membranes secondary to intraocular inflammation. We injected a single injection of Bevacizumab (2.5 mg/0.1 ml) and evaluate visual acuity , Fluorescein angiogram and retinal thickness by Optical Coherence Tomography (OCT) in 4 patients with Vogt Koyanagi Harada disease, 1 patient with Serpiginous Choroidopathy and 1 patient with Multifocal Choroiditis.

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.

To report the long term prognosis in patients with punctate inner choroidopathy (PIC) or multifocal choroiditis (MFC) and associated zonal outer retinopathy (ZOR).

To evaluate the long-term outcome of active choroidal neovascularization (CNV) in punctate inner choroidopathy (PIC) or multifocal choroiditis (MFC) after anti-vascular endothelial factor treatment.
