Retinal stroke (CRAO) and brain stroke connection — sudden vision loss, artery territory, and urgent imaging (Advanced)

Advanced course: sudden painless vision loss in one eye can be a retinal artery occlusion (‘eye stroke’) and is treated as a stroke emergency. Learn what it looks like, what imaging/workup evaluates sources (carotid/cardiac), and safety questions.

If a patient develops new or worsening stroke symptoms, reduced consciousness, seizure, severe headache, airway/swallowing danger, or unstable vital signs, activate emergency response and follow local stroke escalation protocols.

Key takeaways

  • Recognize CRAO as stroke emergency presentation
  • Explain link between eye stroke and carotid/cardiac embolic sources
  • Explain imaging/workup concepts (brain imaging + carotid imaging)
  • Know urgent questions about timeline, ophthalmology, and secondary prevention
