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.

Retinal vein occlusion (RVO) is an obstruction of the retinal venous system by thrombus formation and may involve the central, hemi-central or branch retinal vein. The most common aetiological factor is compression by adjacent atherosclerotic retinal arteries. Other possible causes are external compression or disease of the vein wall e.g. vasculitis.

Each case of retinal vein occlusion is unique. The mild cases of vein occlusion may get better without treatment but only 1o to 20% of cases with severe occlusion may recover some vision. The majority of patients with CRVO do not recover vision and often get worse if left untreated for several months. This is due to development of irreversible scarring. There is some evidence that delaying treatment for months may reduce the chances of visual recovery. Click here to read more.
Retinal vein occlusion (RVO) is the second most common retinal vascular disorder following diabetic retinopathy and is often associated with vision loss. Retinal vein occlusion occurs when there is a partial or complete obstruction of a retinal vein, and it is classified by the location of the occlusion. Click here to read more.
Central retinal vein occlusion (CRVO) results from thrombosis of the central retinal vein when it passes through the lamina cribrosa. Branch retinal vein occlusion (BRVO) is caused by venous thrombosis at an arteriovenous crossing where an artery and vein share a common vascular sheath. The two main complications of RVO are macular oedema (MO), and retinal ischaemia leading to iris and retinal neovascularisation. Thrombosis of the retinal veins cause an increase in retinal capillary pressure resulting in increased capillary permeability and leakage of fluid and blood into the retina. Click here to read more.
