Active clinical trials for "Macular Degeneration"

The aim of the TITAN study is to describe the clinical practices of a cohort of patients with wAMD refractory to ranibizumab (persistence of intra-retinal and/or subretinal fluid) who switch to aflibercept after less than 12 months of ranibizumab treatment. The study will be conducted in real-life conditions and will allow describing conditions of use of aflibercept in patients refractory to ranibizumab

Age-related macular degeneration (AMD) is the leading cause of blindness in non-Hispanic white Americans. Neovascular AMD is an advanced form of macular degeneration that historically has accounted for the majority of vision loss related to AMD. The presence of choroidal neovascular membrane (CNV) formation is the hallmark feature of neovascular AMD. Choroidal neovascular membranes consist of buds of neovascular tissue and accompanying fibroblasts from the choroid perforating Bruch's membrane with extension either above or below the retinal pigment epithelium. These neovascular complexes are associated with hemorrhage, fluid exudation and fibrosis formation resulting in photoreceptor damage and vision loss. Treatment of neovascular AMD consists of injecting inhibitors of vascular endothelial growth factor (VEGF) into the vitreous cavity to interfere with proliferation of choroidal neovascularization and to reduce vascular permeability. OCT is an imaging technology that can perform non-contact cross-sectional imaging of retinal and choroidal tissue structure in real time. It is analogous to ultrasound B-mode imaging, except that OCT measures the intensity of reflected light rather than acoustical waves. This observational study will use OCT technology to study and compare the retinal and choroidal anatomy and blood flow in two groups of patients with neovascular AMD: treatment naïve group and active treatment group. The purpose of this study is to assess the utility of OCT angiography in the evaluation of NVAMD.

Retrospective, non-interventional, observational multi-center field study. Patients diagnosed with wet Age-related macular degeneration (wAMD) and having started treatment with ranibizumab between January 1, 2009 and December 31, 2009 must be consecutively screened and, if eligible, enrolled. Patients will be followed up at maximum until December 31, 2011. Switch to any other Anti vascular endothelial growth factor (anti VEGF) treatment will be documented. For each patient, demographics, medical history, administered treatments, results of ocular and visual assessments and other tests (where available) will be documented.

Age Related Macular Disease (AMD) is easily the leading cause of blindness in older people in developed countries. It affects between 30 and 50 million individuals worldwide, with around 30% of the over 65's showing early signs of the disease. Severe AMD has a devastating impact on the quality of life; it causes extensive visual impairment, making reading difficult and driving impossible. Patients lose their independence and become a major burden on public health systems. Present treatment options are limited. Many new therapies are under development and all will need evaluation using a test with high specificity and sensitivity for early AMD. The present application will develop such an instrument. The prototype was funded by a previous i4i FS (feasibility study ll-FS-0110-14036). The new device measures sensitivity to a dim flickering light using the same principle as an established european conformity marked (CE marked) instrument. The original method involved lights of different wavelengths and higher intensities. The instrument in this study assesses night vision, which is selectively damaged in early stage AMD. In low lighting, the investigators vision depends on specialized rod photoreceptors. Cone photoreceptors, which provide daytime vision, remain normal in the early stages of the disease. By the time patients complain of reduced (cone-based) visual acuity, they will have had the disease for many years and lost many thousands of photoreceptors.

Dry age-related macular degeneration (AMD) is a common cause for severe visual loss in the elderly and represents an unmet need. So far no treatment is available for geographic atrophy (GA), which represents the advanced dry form characterized by expanding areas of outer retinal atrophy with corresponding absolute scotoma. The foveal retina may be spared until late in the course of the disease, a phenomenon termed "foveal sparing". However, the disease process ultimately also involves the central retina leading to irreversible loss of central vision. While the natural history of eyes with GA has been extensively studied with regard to the entire atrophic area, morphology-function analyses for "foveal sparing" GA in particular are still missing. Such data are needed for various purposes including the future use in interventional pharmacological trials aiming to slow the progression of GA and to preserve the foveal retina. In this study, different imaging modalities for accurate detection and quantification of preserved foveal retinal areas will be assessed.

Patients with AMD who are being or have been treated with eye injections of drugs known as anti-VEGF agents with either good or poor response will have DNA collected with check swabs for analysis.

To investigate pathomorphological and functional variations of choroidal neovascularization (CNV) in age-related macular degeneration (AMD) in a Chinese population using optical coherence tomography (OCT) to find which kinds of Fundus characteristics indicated exudative AMD.

The study will be designed as a case control evaluation to compare the genetic profiles of three groups of patients categorized according to diagnosis. Group 1 - CNV secondary to CSC Group 2 - CSC without CNV Group 3 - CNV secondary to advanced AMD.

Age-related macular degeneration (AMD) is a major cause of deep visual acuity loss. Because of progressive deterioration of the macula, patients with AMD complain about progressive visual problems that can impair their quality of life in the physical, mental and social domains. The principal objective principal of this study is to describe the evolution of quality of life between the diagnosis of secondary atrophic AMD and at 18 months after confirmation of diagnosis.

This pathology, DMLA, whose evolution is chronic, requires regular follow-up and care (IVTs) over a long period (several months or even years). Increasing the number of patients to be followed and treated poses increasing problems for ophthalmologists to ensure regular follow-up of patients, followed by a need for satisfactory functional results. Moreover, this regular follow-up imposes enormous constraints on patients and their families (some children or patients are still working). Studies are beginning to emerge on the reliability of patient follow-up in telemedicine. The use of a measure of visual acuity by patients, Electronic Tablet (TE) or computer (O), and at home, seems a logical step to help us improve the quality of patient follow-up while spacing controls. The aim of our study is thus to demonstrate that the measurement of the VA performed by TE or O is reliable. Indeed, during the follow-up of the patients, in the case where the patient's AV decreases, and whatever the reason
