Filter by:This study seeks to evaluate a system for the automated early detection of Age-Related Macular Degeneration (AMD). AMD is a condition in which there is breakdown of the macula of the eye, the part of the retina that is responsible for sharp, central vision. We will take pictures of subjects' eyes using an automated camera. These photographs will be securely transmitted and and then analyzed by a computer program which has been developed in other studies. The outcome of the computer program analysis will be compared with human analysis of these same pictures. If the computer analysis is has good enough accuracy, then this computer system could be used for wide-scale screening for AMD.
The objective of this study is to demonstrate the safety and effectiveness of the SING IMT (Smaller Incision New Generation Implantable Miniature Telescope) 3X implant in improving vision in patients with central vision impairment associated with end-stage Age-related Macular Degeneration (AMD). Eligible patients will be implanted with the SING IMT device and will be followed-up for a period of 12-months with post-operative ophthalmic exams and low-vision rehabilitation sessions.
Age-related macular degeneration (AMD) is the leading cause of irreversible vision loss worldwide, and nearly two million Australians have some signs of AMD. This proposed project is a prospective, observational study that seeks to to understand the underlying aetiology of AMD, factors associated with differences between age-related macular degeneration (AMD) phenotypes or severities, or between AMD and healthy individuals. It also seeks to understand the natural history of AMD progression and the factors associated with the rate of progression. In this project, the disease phenotype, genotype and severity and rate of progression will be determined based on non-invasive clinical imaging or functional assessment of the retina, from obtaining biological samples from the participants, or from patient-reported outcomes.

Age-related macular degeneration (AMD) affects 2 million people in France and is the main cause of irreversible blindness in France. All patients initially have an early form of the disease. This early form can evolve in two different ways: the atrophic form, which progresses slowly, and the exudative or neovascular form, which has a more rapid evolution. While there are treatments for the exudative form of the disease, there is currently no therapy for the atrophic form of AMD. Recently, it has been demonstrated in atrophic AMD that there is accumulation of inflammatory cells, monocytes, in the sub-retinal space. This space is located between the retinal pigment epithelium (RPE) and photoreceptors. It is physiologically devoid of immune cells (immune privilege). Monocytes secrete many pro-inflammatory molecules, such as cytokines. Some cytokines (IL-1, IL6 and TNF) have a deleterious role on RPE and photoreceptors in mouse models. The identification of specific cytokines would help to better understand this disease and consider potential targeted therapies. Our project is based on the hypothesis that monocytes extracted from patients with AMD have a superior survival on RPE compared to monocytes extracted from healthy patients (without retinal pathology), and more particularly in atrophic forms of AMD. The main aim of this study is to compare the survival of monocytes extracted from patients with atrophic AMD to monocytes extracted from patients without retinal pathology (control) on retinal pigment epithelial cell lines (ARPE-19). Survival will be evaluated by automated counting of monocytes after 24 hours of culture on ARPE-19 after specific immunostaining of monocytes. If the survival of monocytes from patients with the late form of AMD is increased then therapy directly targeting this pathological accumulation of monocytes could be considered. Moreover, the identification of increased secretion of certain cytokines and the demonstration of their deleterious effect on retinal physiology could lead to targeted therapies against them.
Evaluation if a computer-based tutorial ("MacInfo" tool) improves the patients' knowledge about intravitreal drug injections, associated risks, and the underlying diseases of treatment-naive patients.
To identify biomarkers of common eye diseases based on single-cell sequencing technologies using PBMC samples. These diseases include uveitis, diabetic retinopathy, age-related macular degeneration and polypoid choroidal vasculopathy. Our study may provide new insight into the underlying mechanisms, and reveal novel predictors and intervention targets for the diagnosis, prognosis and treatment of these diseases.
The purpose of this research study is to investigate the link between age-related macular degeneration (AMD or ARMD) and coronary artery disease (CAD). Age-related macular degeneration is a medical condition which may result in blurred or no vision in the center of vision. Coronary artery disease is a blockage of one or more arteries that supply blood to the heart. The study will specifically look at the macular changes that occur in the retina, which is the sensory membrane that lines the inner surface at the back of the eyeball, and the relationship between coronary heart disease and the risk factors.
Monocentric and prospective study, evaluating the benefit of self-monitoring optimized by therapeutic education either by the environmental Amsler or the Amsler grid according to the patient's choice and to determine the patient's ability to determine the reality itself recidivism and therefore the need for treatment.
The main objective of this pilot study is to evaluate the ability of 68Ga-NODAGA-RGD PET imaging to demonstrate, in patients with unilateral AMD, a molecular therapeutic response to intraocular antiangiogenic injections at the end of the first phase. induction (after 3 months of treatment).
