Filter by: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 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).
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.
The purpose of this study is to determine whether ranibizumab will be effective in reducing if not eliminating the macular edema associated with the disease, central retinal vein occlusion (CRVO).
The RAVE (Rubeosis Anit-VEgf) trial, utilizes monthly intravitreal Ranibizumab (Lucentis) injections for 9 months to see if total VEGF blockade will prevent neovascular glaucoma and eliminate the need for panretinal photocoagulation in patients with ischemic central retinal vein occlusion.
The purpose of this study is to evaluate the effect of intravitreal injections of Macugen every 6 weeks for the treatment of macular edema secondary to branch retinal vein occlusion (BRVO). We hypothesize that macular edema secondary to BRVO is mediated by VEGF 165 and that chronic suppression of VEGF 165 will successfully treat BRVO related macular edema.
The purpose of this study is to examine the effects of Lucentis for active Central Retinal Vein Occlusion with Macular Edema
Patients with Central Retinal Vein Occlusion will undergo vitrectomy, a small needle of about 71 micron will enter a branch retinal vein and TPA will be injected into the obstracted vein.
Natural evolution of severe central retinal vein occlusion with low visual acuity is very poor. A randomized clinical trial will compare troxerutin and platelet anti-aggregating agents (drug treatment) versus surgery and drug treatment. Surgery will include vitrectomy and radial optic neurotomy. The primary outcome will be vision measured 6 months after surgery.
The purpose of this study is to determine whether intraocular injection of triamcinolone is effective in the treatment of macular edema in acute branch retinal vein occlusion.
