Affects healthy patients < 50 years

•VA – slight decrease

•APD - absent

•Venous tortuosity and dilatation

•Variable cotton-wool spots and haemorrhages

•Severe disc oedema

•Very good prognosis in 80%

Types of emboli

Cholesterol emboli (Hollenhorst plaques)

•Multiple, bright, refractile crystals

•Often located at arteriolar bifurcations

•Frequently asymptomatic

Causes of retinal artery vaso-obliteration

Haematological disorders may cause recurrent occlusions in young individuals

•Protein S deficiency, protein C deficiency

•Antithrombin III deficiency

•‘Sticky platelet syndromes’ and antiphospholipid antibody syndrome

Branch retinal artery occlusion ( BRAO )

• VA - variable

• APD - mild or absent
