Your patient has haemorrhages in all quadrants/one quadrant of the retina

If in one quadrant, the patient probably has a branch retinal vein occlusion. If in all four quadrants along with visual loss, the patient has had a central retinal vein occlusion. In both cases, refer urgently via letter soon via letter.

If the patient has haemorrhages in all four quadrants without vision loss, check for diabetes and refer according to the diabetic retinopathy guidelines.
