Filter by:The aim of this study is to evaluate the clinical benefits in visual function from dietary supplementation of the Lumega-Z carotenoid liquid-supplement in participants with drusen and at risk of AMD. The effects of Lumega-Z supplementation will be compared to an active comparator, the AREDS2 multivitamin.
To investigate the use of microperimetry and SS-OCT in assessing the natural changes of retinal sensitivity and anatomy in the perilesional zone of geographic atrophy areas in patients with dry age-related macular degeneration.
Surgical outcome of patients with macular drusen and co-existing abnormalities of the vitreoretinal interface, who routinely undergo pars plana vitrectomy with membrane peeling, is evaluated. Best corrected visual acuity as well as optical coherence tomography data are compared at baseline and last follow up. The rate of development of choroidal neovascularization postoperatively is noted.
A randomized, double-masked, placebo-controlled study to evaluate the safety, efficacy and pharmacokinetics of elamipretide in subjects with Age-Related Macular Degeneration with non-central Geographic Atrophy.
Age-related macular degeneration (AMD) is the leading cause of irreversible vision loss in developed countries among people over 50 years of age. Myopic maculopathy is also an important cause of irreversible vision loss. Reduced near visual acuity is still a major problem with all forms of AMD and myopic maculopathy. Various intraocular lenses for near vision (IOLs) or telescopic systems have been described but are not widely accepted and almost all solutions require phakic status of the eye and are implanted during cataract surgery. Therefore, these devices are not appropriated for pseudophakic AMD and myopic maculopathy patients. Scharioth Macula Lens (SML, Medicontur) is a magnifying intraocular lens for pseudophakic patients implanted in the ciliary sulcus in one eye of each patient. The implant has a bifocal optic, with a central 1.5mm diameter optical zone equivalent to +10D add and a peripheral zone optically neutral. The implantation of the add-on SML can improve the near visual acuity of pseudophakic patients with AMD and myopic maculopathy without impairing their distance visual acuity. The principal objective is to compare the near visual acuity, the far visual acuity and the self-reported vision health status before and after the SML implantation.
Age-related macular degeneration (AMD) is the leading cause of blindness among adults in North America. The current standard of care for patients with exudative ("wet") AMD is anti-vascular endothelial growth factor (anti-VEGF) therapy which must be administered by an injection into the eye every 4-8 weeks. MT-0814 is being developed for the treatment of patients with exudative AMD, and could offer an alternative, safer and less burdensome therapy.
Reading performance in patients with Central Vision Loss and age matched controls with artificial scotomas will be measured with and without different kinds of remapping of missing text to different parts of the visual field.
This is a double-masked, multicenter, randomized, placebo-controlled clinical trial, evaluating the efficacy and safety of ALK-001 in participants with Geographic Atrophy (GA) secondary to age-related macular degeneration (AMD). Up to 200 participants will receive ALK-001 while up to 100 participants will receive a placebo.
This research study will examine the safety and effectiveness of ONS-5010 in participants with AMD. The goal is to prevent vision loss by evaluating the effectiveness of ONS-5010 as compared with ranibizumab.
The content of this research project is to identify the angiofibrotic switch, the transition from angiogenesis to fibrosis, in neovascular age-related macular degeneration (nAMD) longitudinally. Despite optimal treatment about 50% of eyes with nAMD develop fibrosis within 2 years, causing irreversible damage to the retina and functional loss. Objective measurement of fibrosis, however, is challenging, since clinical staging is subjective and current imaging modalities such as color fundus photography (CFP), fluorescein angiography (FA) and optical coherence tomography (OCT) often do not allow clear delineation. Novel imaging modalities such as polarization-sensitive OCT (PS-OCT), OCT angiography (OCTA) and adaptive-optics OCT (AO-OCT) offer identification of fibrous components and microvasculature of fibrotic lesions non-invasively with highest precision and shall thus be used in this study. Hypotheses: The investigators hypothesize to detect and quantify subclinical (i.e. not detectable on dilated fundus examination) areas of fibrosis using PS-OCT and determine the rate and exact location within the neovascular lesion. Furthermore, the investigators expect neuroretinal and microvascular changes, which will be assessed by AO-OCT and OCTA. Methods: Eighty eyes of 80 patients with chronic nAMD will be included and examined cross- sectionally to evaluate the accuracy of PS-OCT to detect and quantify fibrosis in comparison to gold standard imaging modalities. In addition, OCTA and AO-OCT will be performed to analyze the relationship between fibrous, neovascular and neuroretinal structures. Furthermore, forty eyes of 40 participants with treatment-naïve nAMD will be included and followed over 12 months with predefined follow-up intervals. Novel non-invasive imaging will be applied to objectively determine the exact time and extent of the angiofibrotic switch in nAMD during state-of-the- art therapy. This approach has not been done before and is clinically relevant for multiple reasons: Firstly, only little is known about the development of fibrosis in AMD during therapy. Secondly, the clinical diagnosis of subretinal fibrosis is subjective and does not allow reliable quantification. Thirdly, current gold standard imaging modalities (i.e. CFP and FA) for detection of fibrosis involve invasive and time-consuming procedures and do not allow three-dimensional analysis. Finally, our study may identify objective endpoints for future interventional trials.
