When a retinal vein blockage occurs, fluid is unable to drain from the retina sufficiently. This build-up of fluid may cause blurred or curved vision.
Anti-Vascular Endothelial Growth Factors or Anti-VEGF’s such as Avastin and Eylea are medications that help clear the fluid build up in the retina. Typically treatment is required for months until the retinal can create the necessary collateral blood vessels to manage the fluid build-up.
In cases in which Anti-VEGF treatment does not clear a blockage, you may require a sufficient amount of fluid steroid or laser treatment.
