title: Selective B-wave reduction with congenital cataract in neurofibromatosis-2.
abstract: OBJECTIVE
  To electroretinographically evaluate a case of neurofibromatosis-2 (NF-2).
  
  
  METHODS
  Case report and literature review.
  
  
  METHODS
  A 29-year-old man diagnosed with NF-2.
  
  
  METHODS
  Electroretinography (ERG), ophthalmic biomicroscopy, and ultrasound examination results were reviewed.
  
  
  RESULTS
  The ERG of one eye showed selective reduction of b-wave amplitudes. A characteristic posterior subcapsular lens opacity also was observed in that eye. A dense white congenital cataract and a retinal detachment were detected in the fellow eye.
  
  
  CONCLUSIONS
  An inner retinal dysfunction, as evidenced by an abnormal ERG, may occur in NF-2. Further ERG evaluation of other patients with NF-2 is indicated to determine possible associations between NF-2 and selective b-wave reduction.
