Active clinical trials for "Macular Edema"

This Phase 1 study will evaluate the safety, tolerability and duration of effect of a helical intravitreal triamcinolone implant for the treatment of diabetic macular edema over a three-year period.

The purpose of the study is to determine whether concentrations of FOV2304 (high dose or low dose) administered in the eye are more effective than placebo in treating patients with diabetic macular edema, following 12 weeks of treatment.

This study is a Phase III, double-masked, multicenter, randomized, sham injection-controlled study of the efficacy and safety of ranibizumab injection in patients with clinically significant macular edema with center involvement (CSME-CI) secondary to diabetes mellitus (Type 1 or 2). This study is identical in design to study NCT00473330 (Protocol ID FVF4170g). The open-label extension phase of the study was stopped after receiving FDA approval of the study drug (ranibizumab) for diabetic macular edema.

This study will evaluate the safety and efficacy of the intravitreal implant of dexamethasone with laser treatment vs. laser treatment alone in patients with diabetic macular edema.

The purpose of the study is to find out if treatment with an intravitreal injection of triamcinolone or an intravitreal injection of ranibizumab can prevent loss of vision caused by panretinal photocoagulation treatment. At the present time, it is not known whether intravitreal steroid or anti-vascular endothelial growth factor (anti-VEGF) injections are beneficial in preventing vision loss after panretinal photocoagulation (PRP) treatment. It is possible that one or both of the types of injections will prevent vision loss after PRP treatment. However, it is not known whether the benefits of the injections will outweigh the risks. It is possible that because of side effects, the injections may not be as good as laser alone in treating the diabetic retinopathy.

Uveitis is an inflammation (swelling and irritation) inside the eye, affecting the uvea. The uvea is the layer of the eye between the sclera and the retina and provides most of the blood supply to the retina. Uveitis is an important cause of visual loss. There are 30,000 new cases of legal blindness each year due to uveitis in the U.S. Sight-threatening complications associated with uveitis include macular edema, which may persist even when inflammation is controlled. The only current treatment for cystoid macular edema (CME) in uveitis patients is oral or regional steroid injections. For patients who don't respond to steroids or who are unable to tolerate steroid therapy, there are no other medical treatments. The aim of this study is to determine if ranibizumab, an FDA-approved treatment for neovascular age-related macular degeneration, is an effective treatment for those patients with uveitis-induced CME who are unable to be treated with or non-responsive to steroids.

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.

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.

Central and branch retinal vein occlusions are major causes of visual loss. Hemorrhage and capillary nonperfusion, when they involve the macula, can contribute to visual loss, but the major cause is macular edema. Focal and grid laser photocoagulation can sometimes provide benefit in patients with macular edema due to branch vein occlusions, but several laser treatments are often needed and recovery of vision can be very slow and incomplete 1. Laser photocoagulation does not provide benefit for macular edema due to central vein occlusions 2. Therefore, new treatments are needed.The objective of this study is to assess the bioactivity of 3 intravitreous injections 0.5 mg or 0.3 mg of ranibizumab in patients with macular edema due to central and branch retinal vein occlusions and correlate activity with peak and trough aqueous levels. The purpose of this research protocol is pilot study to determine if a randomized placebo controlled trial is warranted.
