Active clinical trials for "Retinal Vein Occlusion"

This study compares the efficacy of intravitreal bevacizumab monotherapy only or combined therapy of posterior subtenon's triamcinolone acetonide and intravitreal bevacizumab for the treatment of macular edema associated with branch retinal vein occlusion.

Central retinal vein occlusion (CRVO) is a common cause of vision loss, typically affecting individuals during the fifth through seventh decade of life. Eyes with severe CRVO have a poor visual prognosis because current treatments address only secondary complications of CRVO without treating its cause. Intra-ophthalmic artery injection of a small dose of t-PA (clot busting medicine), also called intra-ophthalmic artery thrombolysis, may reopen the central retinal vein-and address the cause of the disease- without exposing the subject to the risks of systemic thrombolysis. Our project aims to evaluate the safety and efficacy of intra-ophthalmic artery thrombolysis in subjects with CRVO.

The purpose of this study is to look at how effective, safe, and well tolerated Intravitreal Aflibercept Injection is in subjects with Central Retinal Vein Occlusion (CRVO) or Proliferative Diabetic Retinopathy (PDR).

To see if Lucentis 0.5mg combined with Targeted Pan Retinal photocoagulation will decrease the total number of intravitreal injections in a year for ischemic central retinal vein occlusion, hemi-retinal vein occlusions and branch retinal vein occlusions compared to standard of care

Antagonists of the vascular endothelial growth factor (VEGF) pathway are effective in treating macular edema resulting from retinal vein occlusion (RVO). In the eye, the two most widely used anti-VEGF agents are ranibizumab and bevacizumab. Only ranibizumab has been FDA-approved for the treatment of macular edema from RVO, however bevacizumab has been used off-label by many ophthalmologists with good success. Furthermore, the cost of bevacizumab is less than one-tenth the cost of ranibizumab. Here the investigators conduct a six month randomized, prospective interventional trial comparing the effectiveness of ranibizumab with bevacizumab in the treatment of macular edema from RVO. Primary outcome measures are change in central retinal thickness. Secondary measures are change in visual acuity from baseline and change in angiographic properties of macular lesions from baseline after treatment.

Provide efficacy and safety data on intravitreal injections of ranibizumab 0.5 mg in patients with visual impairment due to macular edema secondary to CRVO

The primary Objective of this study is to evaluate the safety and tolerability of intraocular injections of 0.5mg or 2.0mg of ranibizumab in patients with macular edema due to retinal vein occlusion.

This study will evaluate the safety and efficacy of a single intravitreal injection of AGN208397 to treat Macular Edema associated with Retinal Vein Occlusion. This study is being conducted in two stages: Stage 1 will enroll approximately 21 subjects who will receive a single open label intravitreal injection of either 75 ug, 300 ug, 600 ug or 900 ug of AGN208397 and be followed for 12 months post treatment; based on Stage 1 results, Stage 2 will enroll approximately 96 subjects who will receive a single masked intravitreal injection of one of three doses of AGN208397 or Ozurdex® and be followed for 12 months post treatment.
