Filter by:The investigators have developed an image analysis method that can predict the likelihood that a patient with age related macular degeneration (AMD) will progress within 1 year, based on computerized analysis of optical coherence tomography (OCT) images that are routinely acquired in clinical practice on each patient visit to the ophthalmologist. The investigators' goal is to evaluate whether this method will improve the ability to detect AMD earlier and improve visual outcomes in AMD patients by assigning patient risk categories and having patients come back for follow up based on those categories.
The purpose of the study is to evaluate the safety and efficacy of intravitreal (IVT) administration of DE-120 in subjects with treatment-naive active subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD).
To evaluate the safety of intravitreal (IVT) Fovista® administered in combination with anti-VEGF therapy.
Given the aging population who will be affected by wet AMD and lack of effective GA treatment, it is crucial to assess the safety profile of repeated ranibizumab injections in AMD patients with GA, particularly the possible risk of GA development and enlargement. This potential adverse effect has significant implication in the discussions with patients regarding the risks and benefits of AMD treatment and injection frequency. While monthly injections provide slight improvement of visual acuity at 2 years (Martin et al., 2012), the risk of GA enlargement may offset this benefit in visual acuity. Previous studies assessed the association between intravitreal ranibizumab injections and de novo GA development in injection-naïve eyes (Martin et al, 2012, Querques et al., 2012., Grunwald et al., 2014), rather than GA enlargement in patients with preexisting GA. To the best of the investigators knowledge, there has been no prospective study assessing the association between intravitreal ranibizumab injections and rate of GA progression in patients with pre-existing GA. There is also no prospective study comparing the morphological features of GA between patients who are receiving intravitreal injections and those who are not, nor the concordance of GA enlargement rate between the 2 eyes among patients receiving and not receiving treatment.
The purpose of this study is to evaluate the safety, biological activity and pharmacodynamic effect of repeated intravitreal doses of hI-con1 0.3 mg administered as monotherapy and in combination with ranibizumab 0.5 mg compared to ranibizumab 0.5 mg monotherapy in treating patients with choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD).
Phase 2 clinical trial, single site, randomized, subject-masked study to determine safety and efficacy of intravitreal injections of Sirolimus in subjects with wet Age-Related Macular Degeneration (wet AMD) with persistent intraretinal or subretinal edema due to neovascular AMD despite previous AntiVEGF treatment.
Age-related macular degeneration (AMD) is the leading cause of irreversible blindness in industrial countries. Reticular pseudodrusen (RPD) have been recognized as an additional phenotypic characteristic frequently observed in patients with AMD. Several studies have proven that the prevalence of RPD is associated with AMD as well as a high risk of disease progression to geographic atrophy, the late form of dry AMD. The pathogenesis of RPD is yet still incompletely understood. Retrospective studies have demonstrated that the RPD affected retinal area increases over time. Potential factors influencing progression of RPD have not been intensely studied and potentially predictive markers are yet unknown. The primary objective of this study is to characterize RPD progression in more detail and to identify predictive markers of RPD progression and development of AMD late stages.
The purpose of the research study is to evaluate how well the Distortion Correction Data Collection (DCDC) App works. The DCDC App is an experimental software application that is being developed at the University of Nebraska Omaha. The DCDC app will map and draw the visual distortions of patients with Age-related Macular degeneration.
Dry age-related macular degeneration (AMD) is a common cause for severe visual loss in the elderly and represents an unmet need. So far no treatment is available for geographic atrophy (GA), which represents the advanced dry form characterized by expanding areas of outer retinal atrophy with corresponding absolute scotoma. The foveal retina may be spared until late in the course of the disease, a phenomenon termed "foveal sparing". However, the disease process ultimately also involves the central retina leading to irreversible loss of central vision. While the natural history of eyes with GA has been extensively studied with regard to the entire atrophic area, morphology-function analyses for "foveal sparing" GA in particular are still missing. Such data are needed for various purposes including the future use in interventional pharmacological trials aiming to slow the progression of GA and to preserve the foveal retina. In this study, different imaging modalities for accurate detection and quantification of preserved foveal retinal areas will be assessed.
This is a Phase 1/2, open-label, dose-escalation clinical study, enrolling 21 subjects in one of the two treatment groups to determine the effects of topical ocular administration of low dose or high dose MTP-131 given twice a day in subjects with Diabetic Macular Edema and Age-Related Macular Degeneration.
