Active clinical trials for "Macular Edema"

This is a Phase 1 study to investigate the safety, tolerability of the novel plasma kallikrein inhibitor, KVD001 in subjects with diabetic macular edema. The study is the first step to investigate the hypothesis that plasma kallikrein plays an important role in the disease process behind diabetic macular edema in many patients

To compare the anti-inflammatory efficacy of ketorolac of tromethamine 0.4% and nepafenac 0.1% eye drops for prophylaxis of cystoid macular edema (CME) after small-incision cataract extraction.

This study evaluates a new investigational treatment regimen of three consecutive monthly doses of ranibizumab followed by an as-needed treatment regimen, with monthly follow-up for the first three months then two-monthly follow-up until 18 months in patients with visual impairment due to diabetic macular oedema.The aim of the study is to determine if this treatment regimen is effective and safe in these patients.

Birdshot Retine choroidopathy (BRC) is a sight threatening posterior uveitis. The long term visual outcome has recently be studied showing a legal blindness to 14% at 5 years. Visual acuity is threatened by macular edema (80%), macular atrophy, and choroidal neovascularization.

The purpose of this study is to evaluate the safety and tolerability of Ranibizumab in patients with Clinically Significant Diabetic Macular Edema (CSDME). It will also compare treatment outcomes for patients receiving 0.5mg Ranibizumab and higher doses of 1.0mg and 2.0mg Ranibizumab.

The purpose of this study is to investigate the safety, tolerability, bioactivity, and dose response of two different dosages (0.5 mg and 2.0 mg) of ranibizumab (RBZ) in patients with diabetic macular edema (DME).

This study will evaluate the safety and efficacy of a single intravitreal injection of AGN208397 to treat Macular Edema associated with Retinal Vein Occlusion. This study is being conducted in two stages: Stage 1 will enroll approximately 21 subjects who will receive a single open label intravitreal injection of either 75 ug, 300 ug, 600 ug or 900 ug of AGN208397 and be followed for 12 months post treatment; based on Stage 1 results, Stage 2 will enroll approximately 96 subjects who will receive a single masked intravitreal injection of one of three doses of AGN208397 or Ozurdex® and be followed for 12 months post treatment.

According to a recent estimate more than 280,000 people in the United States are affected by uveitis each year. This report, also estimated that uveitis is the reason for 30,000 new cases of blindness/year and up to 10 percent of all cases of blindness. The purpose of this trial is to determine the effectiveness of VEGF blockade with intravitreal pegaptanib in patients with uveitic CME.

: 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.

Summary of Study Rationale Near-infrared light (NIR) via light-emitting diodes (LED) treatment promotes retinal healing and improve visual function following high intensity laser retinal injury by augmenting cellular energy metabolism, enhances mitochondrial function, increases cytochrome C oxidase activity, stimulates antioxidant protective pathways, and promotes cell survival. LED directly benefits injured neurons in the retina, the lateral geniculate nucleus, and the visual cortex, where perception occurs. From a public health perspective, a Light-Emitting Diode (LED) Array study is important to conduct because it has been approved as a non-significant risk (NSR) device for treatment of eye disorders, it has a low cost of treatment, and it may serve as an effective, non-invasive alternative or adjunctive treatment to laser photocoagulation, the current standard of care for DME. Study Objectives and Hypotheses To determine the effects of short term (3 month) near-infrared light (NIR) therapy on anatomic and functional abnormalities of diabetic macular edema as assessed by visual acuity, optical coherence tomography, multifocal electroretinography (mERG) and fundus bimicroscopy. To assess safety of short term near-infrared light therapy in eyes with diabetic macular edema.
