View clinical trials related to Age-Related Macular Degeneration.
Filter by:The goal of this clinical trial is to learn if the areas of stressed cells in the retina correlate to areas of disease identified in standard imaging and whether the images are helpful to identify potential areas of concern before symptoms or disease occurs. The main question it aims to answer is: - to evaluate patterns of increased autofluorescence FPF in the setting of geographic atrophy Participants will undergo FPF imaging using the OcuMet Beacon system.
The goal of this clinical trial is to evaluate the efficacy, safety and pharmacokinetics of elamipretide in subjects with dry age-related macular degeneration (AMD). The main questions it aims to answer are: what is the rate of change in the macular area of photoreceptor loss in subjects who receive a daily dose of elamipretide compared with those who receive a look-alike substance that contains no active drug, and what is the safety and tolerability of elamipretide daily subcutaneous injections. Participants will receive either once daily subcutaneous doses of 40mg elamipretide or placebo and the two treatment groups will be compared.
Study: observational prospective clinical study. Study population: Subjects over 55 years old with drusen secondary to intermediate AMD. Recruitment: at the Medical Retinal Consultation from the Ophthalmology Department of CHULC. Primary outcome: Identifying imaging predictors of iAMD progression.
In the RoTIS study, the investigators would like to test the robotic stabilizer for the subretinal injection of tPA in patients with subretinal hemorrhage during standard-of-care surgery. The surgical devices used during this procedure will be the following: - The robotic stabilizer (prototype - FAMHP approval received) - 41G subretinal needle (CE marked - used within label) - Inicio micro-injection system (CE marked - used within label) The Inicio system mounted with the 41G needle will be held by the robot, and guided by the surgeon towards the required position. When the tip of the needle is in the desired subretinal position, the robotic stabilizer will be locked and the tPA will be injected till sufficient subretinal bleb formation is obtained, with a maximal duration of up to 3 minutes. As performed routinely, the surgical view through the microscope will be video-recorded and while the injection is being administered, the built-in iOCT of the Artevo surgical microscope (Zeiss, Oberkochen, Germany) will be used to scan the retina area around the injection site to record the subretinal bleb formation for later review.
To assess the usability, tolerability, and repeatability of the set of VR headset-based tasks.
The goal of this project is to conduct a clinical trial in 60 participants ranging from age 50-95 with small drusen who are at risk for age-related macular degeneration (AMD). The study will evaluate the effects of 28g of goji berry intake or an equivalent amount and type of fiber, five days a week for six months, on visual health, gut microbiome profiles, skin carotenoid measures, and lipoprotein profiles.
Multicenter, randomized, masked, controlled study of the safety and effectiveness of intravitreally administered ONS-5010.
Age-related macular degeneration (AMD) is the 1st cause of visual impairment after the age of 50. Its most aggressive form, wet AMD, requires regular intravitreal injections (IVI) spaced 4 to 8 weeks apart usually depending on the treatment regimen and the patient's response. The IVI procedure requires a double disinfection with periocular and conjunctival cutaneous povidone-iodine. Antiseptic agents such as povidone iodine are a highly likely factor in the development of dry eye syndrome. Clinical data have demonstrated the abrasive and toxic effects of their use on the ocular surface, especially with repeated exposure (Saedon H, Nosek J, Phillips J. Ocular surface effects of repeated application of povisoden-iodine in patients receiving frequent intravitreal injections. Cutaneous and Ocular Toxicology. 2017;36(4):343-6.). The IVIS study coordinated by Prof. Dot reported impaired ocular surface and quality of life immediately after IVI. The authors suggest 3 levels of action to improve immediate tolerance: (i) improve the basal status of the ocular surface, (ii) reduce the contact time with povidone-iodine which could be toxic to the ocular surface and (iii) improve immediate post-IVI treatment. (Verrecchia S et al. A prospective multicentre study of intravitreal injections and ocular surface in 219 patients: IVIS study. Acta Ophthalmol. 2021 Mar 18). This study is part of the extension of the IVIS study. IVIs are effective and do not currently present a therapeutic alternative. However, their role in the development or exacerbation of dry eye is still poorly evaluated although millions of IVIs are performed each year worldwide (1.3 million in France in 2019). In addition, discomfort after injection is one of the factors that limit adherence to long-term IVI treatment, some patients fearing this repeated act. We propose in this bicentric, prospective, randomized, parallel group study, to evaluate in this context the impact of the continuous consideration of the risk of dry eye. The expected results are the objective improvement of dry eye indicators, comfort and quality of life of patients, all aimed at optimizing the adherence of our patients to their AMD treatment.
This interventional study is a single-center, open label, 26-week study, designed to evaluate the safety and treatment efficacy of K8 in patients with geographic atrophy (GA) due to age-related macular degeneration (AMD). Up to 5 subjects will receive study medication. Study treatment will be administered by intravitreal injections. Participants will have 7 scheduled visits - Screening with baseline (injection), safety visit 2 days after injection, week 4, week 13 (injection), safety visit 2 days after injection, week 17, week 26. Exams will look for continuous changes in visual acuity, change in area of geographic atrophy lesions in diagnostic imaging, response measured by multifocal electroretinogram, change in reading speed, and change in microperimetry response.
The overall goal of the proposed research project is to provide evidence that a specific subtype of neovascularization that may develop in eyes with age-related macular degeneration (AMD) prevents vision loss. This concept challenges the current view that the development of neovascularizations in AMD represents a harmful event in general. Notably, before the era of anti-vascular endothelial growths factor (VEGF) therapy, destruction and surgical removal of neovascular membranes have been tested as treatment options for neovascular AMD. This research project aims to substantiate the hypothesis that type 1 macular neovascularization (MNV) is intrinsically protective, in sense of a positive response to the degenerative processes in AMD. This concept has actually been proposed by pathologists decades ago but has not been systematically investigated in vivo. With the immense advances in retinal imaging, 'sub-clinical', non-exudative type 1 MNVs that are located beneath the retinal pigment epithelium (RPE) can now be detected non-invasively and characterized in vivo. There is currently a growing body of evidence that photoreceptor and RPE degeneration is indeed slowed down in eyes exhibiting type 1 MNV. However, the proof of a direct protective effect of non-exudative type 1 MNV on visual function in AMD is lacking. Here, the aim is to demonstrate relative preservation of function along with preserved structure in the immediate vicinity of type 1 MNV, while there is progressive loss of sensitivity and degeneration in the surrounding tissue.
