Cortical blindness (bilateral occipital stroke) + Anton syndrome — what it looks like and imaging localization (Advanced)

Advanced course: bilateral occipital injury can cause cortical blindness with preserved eye structure. Some people deny blindness (Anton syndrome). Learn symptom patterns, safety issues, and how CT/MRI/CTA localize posterior circulation causes.

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 cortical blindness as a neurologic emergency presentation
  • Explain Anton syndrome (denial of deficit) as a brain symptom
  • Explain imaging: CT for hemorrhage, MRI DWI for bilateral occipital infarcts, CTA/MRA for posterior circulation
  • Build a safety plan for vision loss and supervision

Key takeaways

  • Recognize cortical blindness as a neurologic emergency presentation
  • Advanced stroke care requires reconciling the clinical syndrome with timing, imaging, medication risk, patient context, and local pathway capacity.
  • A safe plan names escalation thresholds, responsible clinicians, patient-facing instructions, and the next step if results or symptoms change.
