Filter by:The purpose of this study is to assess the safety and tolerability of the R:GEN Laser System in subjects with the early stages of age-related macular degeneration.
The purpose of this phase IV study is to identify innovative early imaging parameters as predictors of the long-term clinical response to brolucizumab in terms of fluid resolution in patients with wet Age-related Macular Degeneration (wAMD) with the purpose to evaluate their potential in supporting the treatment regimen choice (q12w or q8w).
This is a phase 3, open-label, multicenter, extension study to evaluate the long-term safety and efficacy of pegcetacoplan (APL-2) in subjects with geographic atrophy (GA) secondary to age-related macular degeneration (AMD) who participated in Study APL2-103 (NCT03777332) or completed the treatment at Month 24 of either Study APL2-303 (Derby, NCT03525613) or Study APL2-304 (Oaks, NCT03525600).
This study is a prospective, observational, non-interventional, multicenter, open-label, single arm study in patients being treated for nAMD with brolucizumab in Portugal.
The purpose of this study is to test whether a kind of brain stimulation called anodal transcranial direct current stimulation (a-tDCS) can be combined with perceptual learning to improve the ability of people with age-related macular degeneration (AMD) or juvenile macular degeneration (JMD) to read words presented to them on a computer screen better than if perceptual learning alone were used. In addition, secondary measures of visual acuity will also be examined to determine whether brain stimulation can allow patients to resolve finer details of an image. The proposed treatment is the application of a-tDCS onto the participant's head, with brain stimulation aimed at Primary Visual Cortex toward the occipital pole, while patients undergo six separate sessions of training. The investigators will test the ability of participants to read words before the start of the training sessions (pre test) and after the completion of all training sessions (post test). This is a between-subjects design, and half of the participants will receive true stimulation, and the other half will receive sham stimulation. The difference between the pre and post tests when receiving active stimulation will be compared to the difference when receiving sham stimulation, because the sham stimulation is not expected to influence reading beyond a placebo. The aim of the study is to examine the potential of concurrent brain stimulation and perceptual learning as an effective treatment for macular degeneration that may be used in conjunction with more traditional eye-based interventions. The investigators hypothesize that the brain stimulation will enable higher performance in the reading task after and secondary measures after perceptual training due to an increase in the cortical excitability of the stimulated brain cells.
To investigate the effects of lutein supplementation on macular pigment density using FLIO and MPOD measurements in patients with age-related macular degeneration and healthy subjects over a course of 6 months.
A 2-year phase 3, multicentre, randomised, parallel-group, sham-controlled, double-masked study. Primary efficacy will be determined at Week 52.

Retinal diseases are currently the leading cause of legal blindness in the developed world. Among these disorders, age-related macular degeneration (AMD) is one of the most prevalent conditions in individuals over 55 years of age. Late AMD, the most severe presentation of the disease, clinically manifests as either geographic atrophy (dry form) or choroidal neovascularization (CNV) (wet form). Although patients with wet AMD only represent 10% of the total cases, CNV is the main and most serious cause of central vision loss. At present, the treatment of wet AMD comprises intraocular injections of certain antiangiogenic agents which act by blocking VEGF (vascular endothelial growth factor). No effective treatment is yet available for dry AMD, though the AREDS (Age-Related Eye Disease Study) has shown that the administration of antioxidant supplements is able to slow progression of the disease. Such vitamin supplements are also indicated in patients who already have severe AMD (both exudative and atrophic) in one eye, since the risk of progression in these cases is high. Recent studies involving new antioxidant and antiangiogenic molecules such as resveratrol, present in grapes and wine, have also revealed great efficacy in slowing the progression of advanced AMD. Hydroxytyrosol is another polyphenol with important antioxidant and antiinflammatory effects in the RPE. Considering the above, the present randomized, multicenter interventional study involving Spanish and Portuguese patients with unilateral wet AMD was designed to compare the effects of two different nutritional supplements: one containing the antioxidants and minerals recommended by the AREDS at doses that can be used in the European Union (Theavit), and the other comprising these same substances plus omega-3 fatty acids (lipidic antioxidant), lutein (pigment protecting against light-induced damage) and resveratrol (antioxidant and antiangiogenic agent) (Retilut).
Phase 1 open-label study to assess the bioactivity, ocular and systemic safety, tolerability, and pharmacokinetics of a single dose injections of EYP-1901 at three dose levels: 440 µg, 2060 µg and 3090 µg in subjects with Wet Age Related Macular Degeneration (wAMD)
