title: Bilateral optical nerve atrophy secondary to lateral occipital lobe infarction.
abstract: OBJECTIVE
  To report a phenomenon of optical nerve atrophy secondary to lateral occipital lobe infarction.
  
  
  METHODS
  Two successive patients with unilateral occipital lobe infarction who experienced bilateral optical nerve atrophy during the follow-up underwent cranial imaging, fundus photography, and campimetry.
  
  
  RESULTS
  Each patient was diagnosed with occipital lobe infarction by cranial MRI. During the follow-up, a bilateral optic atrophy was revealed, and campimetry showed a right homonymous hemianopia of both eyes with concomitant macular division.
  
  
  CONCLUSIONS
  Bilateral optic atrophy was related to occipital lobe infarction, and a possible explanation for the atrophy was transneuronal degeneration caused by occipital lobe infarction.
