Phase I RVC With Ocriplasmin for CRVO

Summary

In central retinal vein occlusion (CRVO) a blood clot blocks the venous outflow of the entire retinal circulation. This leads to retinal and vitreous hemorrhages, retinal edema and neovascularization. The development of a microneedle and surgical stabilizer made it possible to perform a prolonged (10 minutes) retinal vein cannulation with infusion of Ocriplasmin. Ocriplasmin has the advantage over tissue Plasminogen Activator (tPA) that it already is an active enzyme and a strong fibrinolyticum. This study aims to investigate the feasibility and safety of local intravenous Ocriplasmin for CRVO.
