Active clinical trials for "Macular Edema"

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

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

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.

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.

This clinical trial is designed to investigate differences in terms of efficacy (mean change in best corrected visual acuity obtained after 12 months of treatment) and safety, of 3 therapeutic estrategies for non-tractional macular edema in diabetic patients: a) laser alone; b) laser plus tiramcinolon; and c) laser plus bevacizumab.

This study will compare the safety and efficacy of the 700 ug dexamethasone intravitreal implant with ranibizumab 0.5 mg intravitreal injections in patients with diabetic macular edema (DME).

Intravitreal injections of pegaptanib every 4 weeks will be efficacious in treating Diabetic Macular Edema (DME), as compared to injections every 6 weeks.

This study examined the safety and potential efficacy of the monoclonal antibody efalizumab (Raptiva) for treating sight-threatening uveitis (eye inflammation). Efalizumab controls the activity of white blood cells called lymphocytes that cause inflammation. The drug is currently approved in the United States to treat patients with moderate to severe psoriasis. Participants 18 and older with sight-threatening intermediate or posterior uveitis of at least 3 months duration, causing persistent macular edema in one or both eyes, were eligible for this study. The uveitis required treatment with at least 20 milligrams per day of prednisone, or the equivalent, or a combination of two or more anti-inflammatory treatments such as prednisone, methotrexate, cyclophosphamide, cyclosporine, etc. Participants underwent the following tests and procedures: Medical history and physical examination. Weekly efalizumab treatment. Weekly eye examination, including measurement of vision and pressure in the eyes, dilation of the eyes and examination of the front and back parts of the eye. Weekly blood tests to measure the number and types of cells in the blood and to check for signs of inflammation and treatment side effects. At some visits, blood samples were collected to measure how much efalizumab remains in the blood and whether the body has developed an immune response to the medicine. Blood draw at enrollment and at 2 and 4 months for research tests to examine how participants' immune response was operating. Fluorescein angiography at enrollment and 1 and 3 months after enrollment, unless additional tests are needed, for medical management. This test checked for abnormalities of eye blood vessels. A yellow dye was injected into an arm vein and travels to the blood vessels in the eyes. Pictures of the retina (the back portion of the eye) were taken with a special camera that flashes a blue light into the eye. The pictures show whether any dye has leaked from the vessels into the retina, indicating possible abnormalities. Monthly pregnancy test for women who could become pregnant. Participants returned for treatment and clinic visits weekly for 16 weeks. After 16 weeks, participants whose macular edema had decreased and whose vision may have improved were offered to continue the injections.

This study will provide preliminary data on the dose and dose interval related effects of intravitreally administered Avastin on retinal thickness and visual acuity in subjects with Diabetic Macular Edema (DME) to aid in planning a phase 3 trial. In addition, this study will provide preliminary data on the safety of intravitreally administered Avastin in subjects with DME.

Macular edema constitutes the primary cause of visual impairment in diabetic patients with a disease duration of 20 years or more. Intravitreal triamcinolone (IVTA) and macular focal laser photocoagulation were reported to generate favorable results in the treatment of diabetic macular edema, but there have been patients with diffuse diabetic macular edema refractory to such treatment modalities. The present study will test the safety and the efficacy of the combined treatment of vitrectomy, IVTA and macular focal laser photocoagulation in the treatment of intractable diffuse diabetic macular edema.
