Active clinical trials for "Macular Edema"

The purpose of this study in to compare the efficacy of treatment of diabetic macular edema (DME) using Ranibizumab (Lucenti®), Aflibercept (Eylea®) and Aflibercept (Eylea®) plus Ranibizumab (Lucentis®). It is a randomized clinical trial that will evaluate the efficacy of the combination of two substances currently used in the treatment of DME. Will be allocated in different four groups randomly pacients who receive treatment with intravitreal injections of ranibizumab, aflibercept or a combination of aflibercept and ranibizumab.

The primary objective of the study was to compare the efficacy of intravitreal (IVT)-administered REGN910-3 compared to intravitreal aflibercept injection (IAI) in improving best corrected visual acuity (BCVA) in participants with diabetic macular edema (DME).

This study evaluates the effects of subconjunctivally injected bevacizumab in patients with diffuse diabetic macular edema.

Since 2004, intravitreal injection of Avastin, Lucentis, and Macugen for wet age-related macular degeneration, retinal vein occlusion, and diabetic macular edema are being administered in the United States at increasing rates. A 2010 study showed that in Canada and the incidence of injections grew 8 fold from 2005 to 2007 to 25.9 injections per 100,000 citizens. (Campbell 2010) In 2009, in the United States, over 1 million intravitreal injections were administered to Medicare beneficiaries. (Wykoff 2011) In the year 2011, the four doctors in my retina group administered a total of 6,494 intravitreal injections; in 2010, we administered 5021 intravitreal injections. Even though intravitreal injections are commonly administered, the optimal method of anesthetizing the eye prior to injection has yet to be determined. Some physicians use an anesthetic drop, some a soaked cotton pledget, some use an anesthetic gel and some use subconjunctival injected anesthetic. In 2009, the last time the Procedures and Trends Survey (PAT) (Mittra 2009) conducted by the American Society of Retina Specialists (the largest retina society in the world) asked about anesthetic methods for administering intravitreal injections, the following response was given by the 433 respondents: Topical anesthetic drop: 21.48% Topical viscous anesthetic: 23.33% Topical anesthetic & soaked cotton-tip or pledget: 29.79% Subconjunctival injection of anesthetic: 24.02% Other: 1.39% An editorial in 2011 in the journal Retina, discusses the lack of good studies assessing optimal anesthetic prior to intravitreal injections. (Prenner 2011).

The purpose of this study is to evaluate the safety, pharmacokinetics, pharmacodynamics, and pilot efficacy of multiple ascending dose levels of AKB-9778 given as subcutaneous injections daily for 28 days in patients with diabetic macular edema (DME).

This study will examine the use of the dexamethasone implant (Ozurdex) in patients with macular edema associated with an epiretinal or preretinal membrane requiring surgical intervention. After the surgery is performed (pars plana vitrectomy), an Ozurdex implant will be placed in the eye. Patients will be followed for 1 year.

The purpose of this research study is to determine if a "Treat and Extend" regimen (increasing the time between visits when the disease is stable and not getting worse) of Ranibizumab 0.3 mg injections inside the eye is safe and effective at treating patients with swelling of the retina from diabetes.

Monthly intravitreal ranibizumab (IVR) during the first 6 month had great effect for macular edema with branch retinal vein occlusion (BVO) both in visual and anatomical outcome. It is expected that similar results could be obtained by less frequent IVR. The purpose of this study is to investigate if IVR by PRN is as effective as by monthly. In addition, the investigators are going to study the relationship between macular edema and the size and location of retinal non-perfusion area.

A phase 4 trial evaluating the effect and safety of ILUVIEN in chronic DME patients insufficiently responsive to available therapies.

This interventional study will evaluate the retinal vascular dynamics associated with Intravitreal Aflibercept Injection (IAI) therapy in eyes with diabetic macular edema (DME) or macular edema secondary to retinal vein occlusion (RVO). Ultra-widefield fluorescein angiography and optical coherence tomography (OCT) angiography will be performed at multiple timepoints to assess the changes in retinal vascular leakage, ischemia, and vascular abnormalities throughout the study duration and compare these alterations to baseline.
