title: Optic neuritis following albendazole therapy for orbital cysticercosis.
abstract: OBJECTIVE
  To report the occurrence of optic neuritis following oral albendazole therapy for orbital cysticercosis.
  
  
  METHODS
  Two patients having definitively diagnosed orbital cysticercosis at the orbital apex developed an acute visual loss 1 week after initiation of oral albendazole. Ultrasonography and magnetic resonance imaging determined that the cause was optic neuritis due to disorganization of the cyst with inflammation of the adjacent optic nerve.
  
  
  RESULTS
  Oral corticosteroids (prednisolone 1 mg/kg per day) given for a period of 4 weeks led to resolution of the optic neuritis, with full visual recovery.
  
  
  CONCLUSIONS
  Corticosteroids should be given in addition to albendazole in the treatment of orbital cysticercosis when cysts are in close proximity to the optic nerve.
