title: [Acute bilateral amaurosis in sphenoid empyema caused by Streptococcus pneumoniae].
abstract: METHODS
  A 14-year-old boy suffered from an acute bilateral blindness which occurred in 24-h time, accompanied by headache and raised temperature, with inconspicuous optic nerve head and fundus. After diagnosis of empyema with magnet resonance tomography (MRT) the sphenoid sinus was fenestrated and streptococcus pneumoniae isolated. Liquor and serology being inconspicuous, there was no evidence of leucaemic or autoimmune disease, intoxication or intracranial tumor.
  
  
  METHODS
  The condition of the patient improved under systemic antibiotic therapy. The bilateral amaurosis remained and opticus atrophy developed.
  
  
  CONCLUSIONS
  A bilateral amaurosis with descending opticus atrophy as a consequence of a sphenoiditis and spreading inflammation to the meninges and the optic nerve in the area of the chiasm is a rare event. The imaging technique of the MRT offers new opportunities for an early and more pointed diagnosis and therapy.
