Purpose: 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.
Method: Case report.
Result: Removal of the copper foreign body resulted in electroretinographic improvement and the patient has retained good vision.
Conclusion: 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.
