Active clinical trials for "Retinal Vein Occlusion"

Background: - Branch retinal vein occlusion (BRVO) is a blockage of the small veins that carry blood away from the retina in the back of the eye. It often leads to macular edema, a swelling of the retina that is a common source of vision loss. Studies suggest that inflammation might be a cause. Minocycline is a drug that might help prevent cells involved in inflammation from becoming activated. It is approved for use as an antibiotic, but it has not yet been tested to see if it can treat BRVO. Objectives: - To test the safety and effectiveness of minocycline as a treatment for branch retinal vein occlusion. Eligibility: - Individuals at least 18 years of age who have branch retinal vein occlusion in at least one eye, with vision between 20/32 and 20/200. Design: This study lasts 2 years, with at least 25 visits. Participants will be screened with a physical exam and medical history. They will also have blood tests and an eye exam. One eye will be selected as the study eye to receive the medicine. Those in the study will take minocycline or a placebo pill twice a day, about 12 hours apart, for 2 years. Participants will have monthly visits for blood tests and full eye exams to study the effect of the treatment. Other exams may include thyroid tests and eye imaging studies. Those in the study may also receive injections of a drug to prevent the growth of new blood vessels in the eye.

This is an open-label, multicenter, extension study of intravitreally administered ranibizumab in two cohorts. The first cohort (reported separately under FVF3426g, NCT00379795) enrolled subjects with primary or recurrent Choroidal Neovascularization (CNV) secondary to Age-Related Macular Degeneration (AMD) who completed the treatment phase of a Genentech sponsored study (FVF2598g (NCT00056836), FVF2587g (NCT00061594), or FVF2428g (NCT00056823)). The second cohort (reported here) enrolled subjects with macular edema secondary to Retinal Vein Occlusion (RVO) who completed the 6-month treatment and 6-month observation phases (12 months total) of a Genentech sponsored study (FVF4165g (NCT00486018) or FVF4166g (NCT00485836)). Patients were enrolled within 14 days of completion of the previous study.

The purpose of this study is to compare ranibizumab injection to hemodilution at the early phase of Central Retinal Vein Occlusion (CRVO) and to determine if the combination of both treatments may have a synergic effect.

Ranibizumab is a humanized anti-vascular endothelial growth factor (VEGF) monoclonal antibody fragment approved in Chile by the Instituto de Salud Pública for the treatment of diabetic macular edema (DME), retinal vein occlusion and age-related macular degeneration. Currently, there is limited epidemiologic information in Chile regarding the incidence of DME and limited experience of anti-VEGF hospital therapy. This study will evaluate the efficacy of intravitreal ranibizumab in Chilean DME patients, to investigate the anatomical and functional improvement following this treatment and to increase the local experience regarding the use of anti-VEGF in the treatment of diabetic macular edema.

The purpose of the study is to determine the effect of Intravitreal Aflibercept Injection (IAI) on previously treated Central Retinal Vein Occlusions (CRVOs) with other Anti-VEGF agents.

This study evaluates long-term safety in patients with macular edema due to Retinal Vein Occlusion (RVO) originally enrolled in the BRAVO & CRUISE trials and subsequently followed in the HORIZON extension trial.

A prospective multicenter study comparing patients with CRVO amd secondary macular edema treated with ranibizumab versus sham. Safety and efficacy will be evaluated. Patients will be randomized in a 1:1 ratio to one of the two arms. 32 patients, 6 months follow up. There will be monthly visits with injection the first three months and subsequently new injection if present edema.

Eyetech Pharmaceuticals Inc. and Pfizer, Inc. are studying an investigational drug, MacugenTM, for the possible treatment of CRVO. An investigational drug is one that has not been approved by the U.S. Food and Drug Administration (FDA). This investigational drug may slow the growth of abnormal blood vessels in the eye and may reduce tissue swelling in the eye. The purpose of this study is to compare the safety and efficacy of a Macugen™ injection to a "pretend" injection. In addition, the purpose of this study is to measure the action of the study drug in the body over a period of time and to check for the presence of the study drug in your blood (called pharmacokinetics or PK). This study will involve approximately 90 people. People who decide to participate will have an equal chance (1 in 3) to receive one of three study injections, two of which are Macugen™ and one of which is a "pretend" injection.

The SCORE Study will compare the effectiveness and safety of standard care to intravitreal injection(s) of triamcinolone for treating macular edema (swelling of the central part of the retina) associated with central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO).

This is a study of subjects with retinal vein occlusion (RVO) specifically looking at the difference in outcomes between patients with posterior vitreous detachment (PVD) and those without PVD. Posterior vitreous detachment is a condition where the gel-like substance that occupies the space between the retina and the lens of the eye liquefies and separates from the retina. 20 subjects from Barnes Retina Institute will be enrolled in this study. Based on a pre-treatment ultrasound (a test utilizing high-frequency sound waves to look at the inside of the eye), high resolution OCT (a noninvasive procedure called optical coherence tomography to check the thickness of your retina) and clinical exam, subjects will be assigned to one of 2 groups at baseline: Group 1 will be those with PVD and Group 2 will be those without PVD. Then subjects will receive monthly intravitreal (inside the eye) injections of Ranibizumab.
