Symptoms vary according to the area of retina involved, and most importantly, whether or not the fovea is involved. If the fovea becomes ischaemic or oedematous, then visual acuity is affected.
Please aim to refer patients with acute retinal vein occlusion fairly quickly, with a view to getting an appointment within 1-2 weeks. Please review their cardiovascular risk factors in parallel with the referral.
More detailed information about Retinal Vein Occlusions can be found in the following patient information leaflet.
