Electrophysiologic imaging of retinal and optic nerve damage: the multifocal technique

Multifocal VEP technology is still in its infancy. Although many aspects of the recording and analysis will be improved with time, the mfVEP can be used in the clinic today. It can help to identify functional (nonorganic) problems, demyelinating diseases, glaucomatous damage, and poor field takers. Given the software and techniques needed to record and interpret the results, mfVEP testing should be performed in centers experienced with this technique.
