title: [Visual disorders induced by therapeutic levels of digoxin].
abstract: METHODS
  An elderly patient was referred to the ophthalmologist for evaluation of photopsia. An ophthalmic examination demonstrated no objective visual alterations. The patient had been receiving digitalis for two months. We suspected digitalis intoxication and the patient was remitted to the Emergency Service. The patient's digoxin blood level was normal. We obtained a rapid improvement in the patient's symptoms by discontinuing the medication.
  
  
  CONCLUSIONS
  We must remember that ocular toxicity may occur with therapeutic blood level of the medication and not only when the intoxication appears.
