Filter by:It is well known that blindness is one of the most feared disabilities expressed by patients in the United States. Estimates of the economic impact of visual disability in the current population exceed 30 million US dollars in this country alone. The reasons for this figure are many; however age related macular degeneration (ARMD), diabetic retinopathy, glaucoma and uveitis are responsible for the majority of permanent visual disability and hence the costs in both quality of life and placing an economic burden on society. Research that may help reverse various abnormal biological responses that lead to or worsen clinical manifestations of diabetic retinopathy would be valuable.
This study will assess the safety and efficacy of FA Intravitreal Inserts in subjects with macular edema secondary to RVO.
To assess the efficacy of oral aliskiren as a therapy for diabetic macular edema
Macular edema is the main cause of vision loss in diabetic patients. Its treatment is mainly based on laser photocoagulation, but has limited results. Alternative treatment are under investigation, such as vitrectomy and intravitreal injections of triamcinolone .The aim of VITRILASE is to compare the efficacy of these two treatments to laser photocoagulation for diabetic macular edema.
This project aims to validate a predictive model of diabetic retinopathy progression to clinically significant macular edema (CSME) needing photocoagulation and/or vision loss. The Coimbra Predictive Model (CPM), based on retinal thickness, microaneurysms number, HbA1C and LDL levels, established on a set of 52 diabetic patients, will be tested on a population of 400 patients/eyes to be enrolled into the study. These patients will perform 2 visits at 6-month interval (V0 and V6) to classify each patient into one of the 3 previously established phenotypes. Two years after (V24) patients will be reexamined. The occurrence of end-points, achieved by the patients, are expected to validate our predictive model.
To validate a new methodology, named Retinal Leakage Analysis (RLA), for mapping the human Blood-Retinal Barrier (BRB) function, in the clinical practice.
: The objective of this study is to determine if bromfenac reduces diabetic macular edema (DME) as an adjunct to argon laser therapy (ALT). Leading cause of Blindness in the working-aged population in the United States. 60% of patients with Type-II DM, and nearly all with Type-I DM progress to Diabetic Retinopathy (DR) in twenty years. Diabetic Macular Edema is the principal cause of vision loss in DR. Approximately 50% of patients with DME will experience a loss of >=2 lines of best-corrected visualacuity (VA) after 2 years of follow-up. The pathogenesis of DME is multifactorial and complex, but intervention stratagem have tended to be singular. Photocoagulation laser applied directly to leaking microaneurysms and a "grid" of laser has been the mainstays of treatment since the publication of the Early Treatment Diabetic Retinopathy Study (ETDRS). This landmark clinical trial was an NIH sponsored, multicenter, controlled study that demonstrated efficacy of laser for diabetic macular edema. It also demonstrated that 20% of patients did not respond. Recent efforts to improve the results are focusing on pharmaceutical interventions injected into the vitreous cavity. The route of administration and lack of substantiated efficacy are problematic.
Triamcinolone and Bevacizumab Intravitreal for Treatment of Diabetic Macular Edema
To evaluate safety, visual acuity outcomes, persistence of choroidal neovascular leakage, and the number of treatments of combination intravitreal bevacizumab and verteporfin photodynamic therapy at standard or reduced fluence level in patients with subfoveal CNV due to age-related macular degeneration.
The purposes of this study is to determine if combination reduced fluence photodynamic therapy and Ranibizumab has: Similar efficacy to Ranibizumab (Lucentis) alone. The ability to reduce the number of intravitreal injection of Ranibizumab or a 13 month period The ability to reduce the number of PDT treatments. The study will also collect information on the safety of combination therapy and single therapy.
