  • Abstract
  • Look Inside

 The author emphasizes the practical usefulness of PENG (photoelectronystagmography) in clinical investigation of nystagmus. The simplicity with which the technical procedure may be applied with its high sensitivity eliminating EMG factors and other signal to noises are the prominent features marking the advantages of relying upon PENG.

 Particularly, the recording of galvanic nystagmus was made feasible only by the use of PENG. An without which ENG recording could not have avoided the intervention of artifacts caused by muscle tremor and by changes of periocular fields that had occurred during galvanic stimulations. However, the merits of PENG are mainly regarded as a means by which the above mentioned artifacts may be avoided.
