Key points

• Amaurosis fugax is transient monocular vision loss caused by retinal ischaemia, most commonly embolic from carotid artery disease
• it is classified and managed as a TIA, requiring the same urgent assessment pathway
• central retinal artery occlusion causes sudden, painless, usually permanent monocular vision loss and is an ophthalmic emergency
