Active clinical trials for "Retinal Vein Occlusion"

The efficacy of anti-vascular endothelial growth factor (VEGF) therapy for branch retinal vein occlusion (BRVO) is shown, but its effect on retinal sensitivity is not fully investigated. The purpose of this study is to compare the changes in retinal sensitivity after ranibizumab therapy or combination therapy of ranibizumab and laser photocoagulation in eyes with BRVO.

Recent studies have shown that intravitreal injection of anti-VEGF agent, Lucentis (Ranibizumab) is effective for macular edema associated with central retinal vein occlusion (CRVO). However, there is little information on whether there are any predictive factors of treatment outcome after this treatment. We plan to perform comprehensive functional and imaging tests to determine significant predictive factors.

The purpose of this study is to determine whether phase variance optical coherence tomography (PV-OCT), a software-based optical coherence tomography(OCT) image processing technology, can be used to generate angiographic images of the retinochoroidal vasculature that are comparable to those produced by fluorescein angiography (FA), the current gold standard diagnostic test.

The primary objective is to demonstrate the non-inferiority of bevacizumab in the treatment of patients with macular edema secondary to a retinal vein occlusion (branch or central) as determined by the change in best-corrected visual acuity in the study eye from baseline to month 6.

The purpose of this study is to evaluate the efficacy and safety of the treat-and-extend regimen extending to 4 months by intervals of 4 weeks using intravitreal aflivercept injection for treatment of macular edema secondary to BRVO.

Retinal vein occlusion (RVO) may lead to series of complications including retinal ischemia, macular edema (ME) and induce vision impairment. Intravitreal injection of Ranibizumab (0.5mg) has been proved to be a safe and effective method for the treatment of RVO-ME. In this study, different treatment regimens of Ranibizumab is applied and the effects is observed at 1-6 months to explore the best regimen for RVO. After 6 months, anti-VEGF therapy and/or laser photocoagulation is used to explore whether laser photocoagulation can maintain the therapeutic effect of Ranibizumab or reduce the injection number.

This randomized clinical trial is conducted to evaluate the effect of three intravitreal injections of bevasizumab versus two intravitreal injections of triamcinolone in acute retinal vein occlusion. The outcomes are visual acuity and central macular thickness. The follow-up time is 6 months.

To evaluate the safety and efficacy of intravitreal recombinant humanized anti-VEGF monoclonal antibody in patients with visual impairment due to macular edema secondary to CRVO

This pilot study aims to establish that treatment with near infrared light (NIR) reduces cystic macular oedema in patients with a retinal vein occlusion.

The purpose of this study is to evaluate the efficacy of intravitreal ranibizumab by determining the pathogenesis of macular edema, which cause a direct effect on visual function. In particular, we focus on the correlation between the treatment effectiveness of ranibizumab and the role of the cytokines involved in the cause of macular edema.
