Central Retinal Vein Occlusion

There is no current evidence that any type of early treatment will alter the visual prognosis in established retinal vein occlusion (CRVO). Non-ischaemic CRVO may resolve without symptoms. However, all patients with suspected CRVO should be urgently referred to ophthalmology for assessment. They may consider starting anti-VEGF (vascular endothelial growth factor) as this can improve vision in patients with macular oedema secondary to CRVO. [19]
