title: Treatment of optic nerve sheath meningioma with three-dimensional conformal radiation.
abstract: OBJECTIVE
  To report a patient recovering vision after three-dimensional conformal radiotherapy for optic nerve sheath meningioma.
  
  
  METHODS
  Radiotherapy was delivered by a three-dimensional conformal technique in 28-180-cGy fractions.
  
  
  RESULTS
  Visual acuity improved from 20/200 to 20/30, and the visual field defect resolved.
  
  
  CONCLUSIONS
  Visual loss from optic nerve sheath meningioma can be reversed by three-dimensional conformal radiotherapy.
