title: Reversible retinal toxicity associated with retained intravitreal copper foreign body in the absence of intraocular inflammation.
abstract: OBJECTIVE
  To report on a patient who developed retinal toxicity from an intraocular copper foreign body in the absence of any signs of chalcosis or inflammation.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  Removal of the copper foreign body resulted in electroretinographic improvement and the patient has retained good vision.
  
  
  CONCLUSIONS
  Retinal toxicity from intraocular copper can be subclinical and such foreign bodies should be removed. Removal of the foreign body can be associated with at least partial reversal of retinal toxicity.
