Central retinal artery occlusion
Retina & Vitreous
Key Points
- •CRAO is an ophthalmic emergency and a 'retinal stroke' - ~25% have concurrent cerebral infarction on MRI. Urgent stroke pathway referral is essential
- •Cherry-red spot with pale retina, RAPD, and attenuated arteries with box-carring are pathognomonic fundus findings
- •Always exclude GCA in patients ≥50 years - check ESR/CRP immediately. Arteritic CRAO requires IV methylprednisolone to protect the fellow eye
- •No treatment has strong evidence for improving vision in CRAO; cilioretinal artery sparing is the most important prognostic factor (~80% achieve ≥20/50)
- •NVI develops in ~18% at 4–12 weeks - regular gonioscopy is mandatory for early detection of neovascular glaucoma
