Summary
To introduce the clinical utility of the absolute value of the reconstructed waveform method in the analysis of multifocal visual evoked potential (mfVEP).
- mfVEP is obtained from electric responses which are generated in a specific region via a cross-correlation following the simultaneous presentation of stimuli to the various regions of the visual field according to the pseudo-random sequence
- mfVEP is made up of electric responses generated from a wide region of the visual field, and is capable of detecting a broad range of optic nerve damage
- detect local defects by providing the local electric responses from the visual field
- mfVEP provides local VEP responses from the visual field. The technique combines conventional VEP recording techniques with a display that is subdivided into a number of regions, each of which has an independent stimulus controlled by specialized software
- mfVEP can detect a broader range of optic damage than conventional VEP
- mfVEP is widely used as an adjunctive tool in the diagnosis of glaucoma, ischemic optic neuropathy and retinal vessels disease
