Other tests in glaucoma: Multifocal visual evoked potential

Abstract

Numerous electrophysiological tests have been proposed for detecting glaucomatous damage. Some involve electrical recordings from the eye, while others involve recordings from the cortex [1]. The focus of this chapter is on the latter, particularly the VEP, an electrical potential recorded with one or more electrodes placed over the occipital region of the skull. A variety of visual displays have been used to record VEPs and standards are available that describe clinical recording and analysis of the conventional VEP [2]. While the VEP is useful in the diagnosis of a variety of conditions [3], to date there is no convincing evidence that any of the standard VEP procedures perform better than standard automated perimetry (SAP) for detecting glaucomatous damage. However, a relatively new technique, the multifocal VEP (mfVEP), can be clinically useful. © 2010 Springer-Verlag Berlin Heidelberg.
