Filter by:The objective of this surveillance is to collect information about 1) adverse drug reaction not expected from the LPD (unknown adverse drug reaction), 2) the incidence of adverse drug reactions in this surveillance, and 3) factors considered to affect the safety and/or efficacy of this drug.
The purpose of the study is to provide efficacy and safety data for monthly ranibizumab 0.5 mg intravitreal injections in Chinese patients with subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD). The study results will support the regulatory submission in China to make ranibizumab available for clinical use.
Age-related macular degeneration (AMD) is the chief cause of severe and irreversible loss of vision in developed countries. The prevalence of AMD increases dramatically with age. The early stage (or dry AMD) is associated with minimal visual impairment and is characterized by large drusen and pigmentary abnormalities in the macula. The late stage is a neovascular, exudative form. This so called exudative AMD includes serous or hemorrhagic detachment of retinal pigment epithelium and choroidal neovascularization leading to severe loss of vision (20/200 or worse). Patients with unilateral CNV (choroidal neovascularisation) have a significant risk of CNV developing in the second eye. Choroidal blood flow is of great importance for normal visual function. Several reports have provided evidence suggesting that choroidal blood flow is decreased in subjects with AMD. In late stages of AMD angiogenesis leads to the formation of choroidal neovascularization that can cause severe visual impairment by disrupting normal macular function. The purpose of this evaluation is to investigate a possible link between alterations in choroidal blood flow and the development of CNV and serous detachment in the fellow eye of patients with AMD and unilateral neovascular maculopathy. This longitudinal study may provide important findings with respect to natural history and visual prognosis of patients with neovascularized AMD. Ocular blood flow will be determined by non-invasive methods, including laser Doppler flowmetry and laser interferometry
The purpose of this study is to report the treatment effect and safety of combined intravitreal bevacizumab (IVB) and photodynamic therapy (PDT) with verteporfin using a reduced (RF) light fluence rate, in choroidal neovascularization (CNV) secondary to pathologic myopia.
To this study and identify the sequence of alterations occurring in the chorioretinal interface during progression of AMD from "dry" AMD to sight-threatening chorioretinal neovascularization (CNV).
To evaluate the clinical results of anti-VEGF intra-vitreal injections (IVT) in CNV secondary to pathologic myopia (PM-CNV).
The study will evaluate the safety and efficacy of the intravitreal dexamethasone implant as adjunctive therapy to Anti-VEGF treatment in the study eye of treatment naïve subjects with choroidal neovascularization secondary to age-related macular degeneration. Subjects will be followed for 26 weeks.
This is a multicenter, randomized, open-label study. 40 patients will be followed for a period of 12 months. All consented and enrolled patients will receive either 0.5mg or 2.0mg of intravitreal ranibizumab injection.
To evaluate safety, visual acuity outcomes, persistence of choroidal neovascular leakage, and the number of treatments of combination intravitreal bevacizumab and verteporfin photodynamic therapy at standard or reduced fluence level in patients with subfoveal CNV due to age-related macular degeneration.
The aim of the study is to evaluate whether PF-04523655 is safe in the treatment of neovascular/wet AMD
