Retinal veins can become blocked when fatty deposits or a blood clot becomes stuck in them.
Central Retinal Vein Occlusion (CRVO) describes a blockage in the main vein supplying the retina.
The condition can be investigated using retinal photography and in particular Fundus Fluorescein Angiography (FFA). These diagnostic imaging techniques usually performed by a specialist photographer can help to pinpoint the location and assess the extent of the damage to the vessels and inform an appropriate course of treatment.
The bright areas show leakage of fluorescein dye from the vessels and the black spots show areas of ischemia where the blood supply is non-exsistent.
