Active clinical trials for "Macular Edema"

The study will evaluate the safety and efficacy of the intravitreal dexamethasone implant in the study eye of vitrectomized subjects with diabetic macular edema. Subjects will be followed for 26 weeks.

The purpose of the study is to find out which is a better treatment for diabetic macular edema (DME): laser alone, laser combined with an intravitreal injection of triamcinolone, laser combined with an intravitreal injection of ranibizumab, or intravitreal injection of ranibizumab alone. At the present time, it is not known whether intravitreal steroid or anti-vascular endothelial growth factor (anti-VEGF) injections, with or without laser treatment, are better than just laser by itself. It is possible that one or both of the types of injections, with or without laser treatment, will improve vision more often than will laser without injections. However, even if better vision outcomes are seen with injections, side effects may be more of a problem with the injections than with laser. Therefore, this study is conducted to find out whether the benefits of the injections will outweigh the risks.

This was a multi-center, randomized, masked, parallel-group, controlled study in patients with diabetic macular edema, comparing RetisertTM (0.59 mg) with control therapy (standard of care (SOC) - repeat macular grid laser or observation). The objective was to evaluate the safety and efficacy of the intravitreal fluocinolone acetonide implant in the treatment of patients with diabetic macular edema.

The purpose of this study is to examine the effects of Lucentis for active Central Retinal Vein Occlusion with Macular Edema

This study will evaluate the safety and efficacy of the intravitreal implant of dexamethasone for the treatment of macular edema associated with branch retinal vein occlusion.

The purpose of this study is to determine whether intravitreal injection of Triamcinolone Acetonide is effective in the treatment of Clinically Significant Diffuse Macular Edema due to Type 2 Diabetes Mellitus.

This study will evaluate the clinical efficacy of intra-vitreal injections of Ranibizumab (Lucentis) in the treatment of Diabetic Macular Edema as compared to grid/focal laser.

This study will compare the side effects of two laser treatments for diabetic macular edema, a common condition in patients with diabetes. In macular edema, blood vessels in the retina-a thin layer of tissue that lines the back of the eye-become leaky and the retina swells. The macula-the center part of the retina that is responsible for fine vision-may also swell and cause vision loss. Traditional laser treatment (argon blue or green, or yellow) for macular swelling, or edema, causes scarring that can expand and possibly lead to more loss of vision. A different type of laser (diode) may have less damaging effects to the eye and fewer long-term adverse effects, but this is not known. The results of this study on side effects of the treatments will be used to design a larger study of effectiveness. The study will also examine whether vitamin E can reduce the damage caused by laser treatment. Patients with elevated cholesterol levels will be invited to participate in a cholesterol reduction part of the study to compare normal-pace cholesterol reduction with accelerated reduction. Patients 18 years of age and older with type 1 or type 2 diabetes and macular edema may be eligible for this study. Candidates will be screened with the following tests and procedures: Medical history and physical examination. Eye examination to assess visual acuity (eye chart test) and eye pressure, and to examine pupils, lens, retina and eye movements. The pupils will be dilated with drops for this examination. Blood tests to measure cholesterol and vitamin E blood levels, blood clotting time, hemoglobin A1C (a measure of diabetes control), and to evaluate liver and kidney function. Eye photography to help evaluate the status of the retina and changes that may occur in the future. Special photographs of the inside of the eye are taken using a camera that flashes a bright light into the eye. Fluorescein angiography to evaluate the eye's blood vessels. A yellow dye is injected into an arm vein and travels to the blood vessels in the eyes. Pictures of the retina are taken using a camera that flashes a blue light into the eye. The pictures show if any dye has leaked from the vessels into the retina, indicating possible blood vessel abnormality. Multifocal electroretinogram to measure electrical responses generated within the retina. The test, which takes about 1-1/2 hours, is painless. Participants will be randomly assigned to take 1600 IU of vitamin E or placebo (an inactive, look-alike pill) daily. After taking the pills for 3 months or more, patients who require laser treatment will be randomly assigned to one of the two laser therapies. (Patients with macular edema in both eyes will receive both treatments, one in each eye.) For these procedures, eye drops are put in the eye to numb the surface and a contact lens is placed on the eye during the laser beam application. Several visits may be required for additional laser treatments. The maximum number of treatments depends on how well they are working. Patients will return for follow-up visits 1, 3, and 6 months after the first treatment, and then every 6 months until either the patient returns for a 3-year visit; the last enrolled patient returns for the 1-year visit; or the patient requests to leave the study. During the follow-up visits, patients' response to treatment will be evaluated with repeat tests of several of the screening exams.

The purpose of this study is to determine if ruboxistaurin can help slow the worsening of an eye disease called macular edema in patients with diabetes.

This study will evaluate whether vitamin E can help treat swelling of the macular area of the retina (the back part of the eye) associated with uveitis (inflammatory eye disease). The macula is responsible for sharp vision; swelling in this area is one cause of vision loss in uveitis patients. Macular swelling is also associated with eye problems related to diabetes. In these patients, the swelling is thought to be caused by a substance called vascular endothelial growth factor, or VEGF. High doses of vitamin E have been used to treat these eye problems in diabetics. This study is a first step to find out if vitamin E will help reduce the retinal swelling in uveitis, which may also be caused by VEGF. Patients 9 years of age and older with macular edema associated with uveitis may be eligible for this study. Candidates will be screened with the following tests and procedures: Medical history and physical examination. This includes measurement of vital signs (blood pressure, pulse, temperature and breathing rate) and examination of the head and neck, heart, lungs, abdomen, arms and legs. Eye examination. This includes measurement of visual acuity using a vision chart, measurement of eye pressure and examination of the pupils and eye movements. The pupils will be dilated with drops to permit examination of the back of the eye. Fluorescein angiography. This test uses a yellow dye (fluorescein) to take photos of the retina. The fluorescein is injected into an arm vein and travels to the blood vessels in the eye. The camera flashes a blue light into the eye and takes pictures of the retina. The pictures show if the dye has leaked from the blood vessels into the retina. Stereoscopic color fundus photography. These are photographs of the back of the eye, taken after the pupils have been dilated with drops. Optical coherence tomography. This test measures the macular swelling. It is used to determine if the swelling is getting worse, better or staying the same. Blood tests. About a tablespoon of blood is drawn to measure inflammation and cell counts and side effects of treatment. Pregnancy test. All women of child-bearing potential are tested for pregnancy. Participants will be randomly assigned to daily treatment with oral high-dose vitamin E (1600 units) or placebo (a pill with no active ingredient) for 4 months. They will be examined at 2 months and 4 months with the same tests performed for screening and will return for a final clinic visit 1 month after treatment has ended.
