Active clinical trials for "Macular Edema"

This is a Phase 2, doubled-masked, randomized study of the efficacy and safety of Intravitreal Aflibercept Injection (IAI;EYLEA®;BAY86-5321) in subjects with diabetic macular edema (DME). Approximately 200 subjects will be randomized in the US, Canada, Australia and EU.

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 aim of this pilot study was to investigate the effects of an intravitreal combination therapy using triamcinolone and bevacizumab in patients with macular edema due to diabetic retinopathy.

The purpose of this study is to compare a single intravitreal injection of 4.0 mg of triamcinolone acetonide and 1.25 mg of bevacizumab for the treatment of diabetic macular edema.

A small percentage of patients with retinal degeneration accumulate fluid in the center of their retina. Previous studies using an oral form of treatment has been successful in decreasing this fluid which improves vision. This study will test the use of a topically applied form of this treatment to the eye to reduce the amount of fluid and improve or preserve vision.

This was a Phase III, multicenter, randomized, double-masked, sham injection-controlled study of the efficacy and safety of intravitreal ranibizumab compared with sham injections in patients with macular edema secondary to central retinal vein occlusion (CRVO); 392 patients with CRVO were enrolled at 95 investigational sites in the United States. The study included a treatment period (6 months) and an observation period (6 months).

This was a Phase III, multicenter, randomized, double-masked, sham injection-controlled study of the efficacy and safety of intravitreal ranibizumab compared with sham injections in patients with macular edema secondary to branch retinal vein occlusion (BRVO); 397 patients with BRVO were enrolled at 93 investigational sites in the United States. The study included a treatment period (6 months) and an observation period (6 months).

This study will evaluate the safety and efficacy of an intravitreal insert of fluocinolone acetonide for the treatment of diabetic macular edema.

This study will evaluate which of the three following treatment options is better for diabetic macular edema: laser alone, steroid injection alone, or steroid injection followed by laser. Macular edema is a swelling in the small central part of the retina - the part of the retina that is used for sharp, straight-ahead vision. Laser treatment is the only treatment that has been proven to be beneficial for diabetic macular edema. It reduces the swelling and lessens the chance of further vision loss, but it does not improve vision. Triamcinolone is a steroid drug that decreases inflammation and scarring. Injections of the drug have decreased macular edema in some patients and improved vision. Swelling may return, requiring repeat injections, and it is not known if the vision improvement is permanent. This 3-year study will examine and compare the benefits and side effects of both treatments, alone and in combination. Patients 18 years of age and older with diabetic macular edema may be eligible for this study. Participants undergo the following tests and procedures. At the beginning of the study: Blood tests to measure HbA1C (measure of diabetes control). Measurement of blood pressure. Eye examination to assess visual acuity (eye chart test) and eye pressure, and to examine pupils, lens, retina and eye movements. The pupils are dilated with drops for this examination. Optical coherence tomography (OCT) to measure retinal thickness. This test shines a light into the eye and produces cross-sectional pictures of the retina. These measurements are repeated during the study to determine if retinal thickening is getting better or worse, or staying the same. Photographs of the retina and lens. A special camera with bright flashes is used to take these photographs. Treatments Some patients will have one eye treated and some patients will have both eyes treated. The treatment for a given individual is determined by chance: Triamcinolone acetonide injection alone. The steroid is injected in the tissue around the eye. Two injection procedures are used in the study, differing in their location and dose. Numbing drops are placed over the area to be injected and the steroid is injected. Laser treatment alone. The surface of the eye is numbed with drops and a contact lens is placed on the eye during the laser beam application. Before the treatment, patients may have fluorescein angiography, in which pictures of the retina are taken using a yellow dye. The dye is injected into a vein and travels to the blood vessels in the eye. The camera flashes a blue light in the eye and takes pictures that show the amount of dye leakage into the retina. Treatments may be repeated at several visits. Triamcinolone acetonide plus laser treatment. Patients who receive both the steroid injection and laser have the steroid injection first and the laser treatment 1 month later. Follow-up Patients return to the clinic for follow-up visits at 1, 2, 4, 8, 12, 24 and 36 months, or more often if needed, after the initial treatment for an eye exam, measurement of visual acuity, and OTC. Photographs of the retina are taken at the 4- and 8-month visits and at the 1-, 2- and 3-year visits. Fluorescein angiography may be done at 4 months. Blood pressure is measured at the 1-, 2- and 3-year visits, and an HbA1c blood test is done at 4 and 8 months and at the yearly visits. Participants may be asked to complete a questionnaire once a year about their vision and medical condition. Treatment options are discussed at the 4- and 8-month visits.

This study is being done to see if the investigational drug Ranibizumab (RBZ) given by injection into the eye, is safe and effective to use in people with diabetic macular edema (DME). The investigators want to compare RBZ to laser treatment which is the current standard way to treat DME. RBZ blocks a growth factor that is thought to be involved in the formation of abnormal blood vessels that cause loss of vision in patients with DME.
