Can be central or branch retinal vein

Branch retinal vein occlusion

• Pathophysiology

Central retinal vein occlusion

• Usually due to a primary thrombus disorder

Non-ischaemic CRVO presents with painless, unilateral loss of vision, no afferent pupillary defect and less severe fundoscopic fundings in comparison to ischemic CRVO

Retinal Vein Occlusion (engorged retinal veins and haemorrhages in streaky pattern)
