title: Residual neurovascular function and retinotopy in a case of hemianopia.
abstract: BACKGROUND
  For occipital cortex strokes resulting in vision disorders, questions about the viability of residual visual cortex remain.
  
  
  METHODS
  In a patient with a one-year-old, left, complete, homonymous hemianopia due to a right, posterior cerebral artery, ischaemic infarct, we assessed the visual cortex with fMRI retinotopic mapping prior to starting vision restoration therapy.
  
  
  RESULTS
  The patient was found to have residual neurovascular function and retinotopic representation in the surviving visual cortex around the infarcted area.
  
  
  CONCLUSIONS
  The ability to respond to stimuli in part of the blind field, though not consciously perceived, suggests the potential for recovery.
