Clinical Trial: Ozurdex for Retinal Vein Occlusion Study (ORVO Study)
Study Status: Completed
Recruit Status: Completed
Study Type: Interventional
Official Title: Ozurdex for Retinal Vein Occlusion Study (ORVO Study)
Brief Summary: To measure the pro-permeability factors in the aqueous humor of patients with persistent/recurrent macular edema after an injection of Ozurdex.
Detailed Summary: To measure various pro-permeability factors in the aqueous humor of patients with persistent/recurrent macular edema despite prior treatment with anti-VEGF agents at baseline and at 4 weeks after intraocular injection of OZURDEX.
Sponsor: Johns Hopkins University
Current Primary Outcome: Number of Participants Who Had a >30% Decrease in the Aqueous Levels of Various Vasoactive Proteins 4 Weeks After an Injection of Ozurdex [ Time Frame: 4 months ]
Original Primary Outcome: The primary outcome measure is a composite outcome that includes change from baseline in aqueous levels of VEGF, SDF-1, and angiopoietin-2 at 1, 2, 3, and 4 months after injection of OZURDEX. [ Time Frame: 4 months ]
Current Secondary Outcome:
Original Secondary Outcome: Measure Efficacy and safety parameters; these are composite outcomes [ Time Frame: 4 months ]
Determine the percentage of patients with CRVO or BRVO with ≥15, ≥10, or ≥5 letters at 1, 2, 3, and 4 weeks after injection.
Determine the percentage of patients with reduction in excess foveal thickness by 50% or 90% at Weeks 24, and 48.
Assess safety parameters including changes in intraocular pressure from baseline.
