Abstract
Purpose: To investigate the usefulness of multifocal visual evoked potential (mfVEP) testing in patients with functional visual loss. Methods: Eight patients, aged between 16 and 40 years (mean age, 25.5 [+ or -] 8.83 years), with clinical presentations typical of functional visual loss, were tested with mfVEP. All patients had complete neuro-ophthalmological examinations. Goldmann or Humphrey perimetry examinations and mfVEP results were compared. Results: The mfVEP test demonstrated robust evoked potentials in areas of visual field 'loss' with Goldmann or Humphrey perimetry in all eight patients tested. All patients showed moderate to severe visual field loss with conventional perimetry. MfVEP was able to clearly record strong signals in the area of reported loss. Conclusion: MfVEP is a useful clinical tool for determining functional visual field loss in moderately cooperative patients.
