Filter by:To determine safety and efficacy of intravitreal injections of Sirolimus with adjunct EYLEA in subjects with exudative age related macular degeneration (AMD) with persistent intraretinal or subretinal edema due to neovascular AMD despite previous intravitreal anti-vascular endothelial growth factor (antiVEGF) treatment.
A Phase 3 Study of the Efficacy and Safety of Squalamine Lactate Ophthalmic Solution 0.2% Twice Daily in Subjects with Neovascular Age-Related Macular Degeneration. Patients will receive injections of ranibizumab. In addition, patients will receive either Squalamine lactate 0.2% eye drops or Placebo eye drops. The study duration is approximately 9 months to primary endpoint
The purpose of this research study is to determine if photobiomodulation is an effective treatment of Dry Age-Related Macular Degeneration (AMD) and vision loss associated with the disease.
Maculopathy induced by retinal toxicity of synthetic antimalarials is to be screened at the sub-clinical stage. Indeed, when the first visual symptoms appear, macular damage is already irreversible and the clinical picture may even continue to deteriorate for several years after the end of synthetic antimalarial use. In opposition, the early termination of hydroxychloroquine in patients showing recent alterations on the multifocal electroretinogram (nfERG) allowed he reversibility of toxic damage over a six month period. It is therefore critical to detect early retinal anatomic changes during retinotoxicity screening before the occurrence of irreversible anatomical and functional consequences. The usual patient monitoring consists of an annual eye examination, detecting subjective functional abnormalities (visual acuity, color vision, central visual field testing) or macular lesions (eye fundus). These abnormalities show a constituted infringement and do not contribute to the early diagnosis of synthetic antimalarial maculopathy. The mfERG is an objective examination, able to detect retinal damage whilst still reversible. It is recommended during the annual monitoring and is, today, the gold standard for the screening and diagnosis of synthetic antimalarial maculopathy. However, its realization is time consuming, requires a good patient cooperation and is difficult to access due to the few ophthalmology centers offering it. In practice, it is rarely done as a systematic annual screening for patients on long-term synthetic antimalarial treatment. It is often limited to second-line studies (for patients already showing functional or anatomical abnormalities) whereas its interest lies in the detection of early lesions. The Optical Coherence Tomography Spectral Domain (OCT-SD) is a non-invasive eye examination, commonly used since nearly 10 years. A special image analysis provides a panoramic viewing of the state of the photoreceptor layer, and a non-invasive detection of any anatomical changes, even subtle, within this layer. The concordance between the "en face" OCT and the mfERG in the screening of synthetic antimalarial maculopathy is considered in this study.
Retinal blood flow measurement is of scientific and clinical value. For this purpose retinal vessel morphology (such as diameter, vessel wall thickness, etc) determination is crucial. Different imaging modalities might provide divergent results. Thus, quantification of such differences is valuable. The present study aims to reveal and quantify differences in vessel morphology between fundus photography, fundus angiography, and optical coherence tomography in health and disease.
The primary objective of the study is to compare the efficacy of intravitreal (IVT)-administered REGN910-3 compared to intravitreal aflibercept injection (IAI).
The investigators will evaluate the concentrations of cytokeratin 8 in aqueous humor in eyes with exudative age-related macular degeneration (AMD) before therapy with intravitreal Ranibizumab, and identify associations with visual and anatomical outcome after treatment.
This study evaluates the treatment of Dry Macular Degeneration and the resulting change in vision with a very, very low current that is similar to what occurs in the body naturally. In Phase 1, 16 participants will be treated, with half receiving treatment and half a sham (no treatment). After the treatment period of one week, those not treated will be treated. In Phase 2, all participants will be treated.
This is a multicenter study designed to evaluate usability of ranibizumab PFS in patients with neovascular age related macular degeneration or macular edema secondary to retinal vein occlusion.
Clinical and genetic evaluation of individuals treated with intravitreal aflibercept injection (Eylea) for neovascular age-related macular degeneration (wet AMD)
