title: Cortical blindness associated with electroconvulsive therapy.
abstract: BACKGROUND
  Neurological syndromes arising in the context of electroconvulsive therapy (ECT) have rarely been reported in literature.
  
  
  METHODS
  We report an adult man who received ECT during a manic episode and who developed prolonged confusion and transient (1 day) bilateral loss of vision immediately after the eighth treatment.
  
  
  RESULTS
  Except for the blindness and the patient's lack of awareness of the symptom, the neurological examination was within normal limits. No abnormality was evident on brain computed tomographic scan. These findings suggest the diagnosis of cortical blindness. The patient was able to see normally when he awoke the next morning. He had complete amnesia for the events of the previous day.
  
  
  CONCLUSIONS
  Transient cortical blindness is probably a very rare adverse effect of ECT. The findings are discussed in the context of visual impairment associated with epileptic seizures.
