Doettl SM, Plyler PN, McCaslin DL. Artifact in Pediatric Oculomotor Findings during Videonystagmography: A Retrospective Analysis. Journal of the American Academy of Audiology. 2017 Apr;28(28). 314-324. PMID: 28418326 [PubMed]
Accurate measurement of oculomotor function using videonystagmography (VNG) is imperative for diagnosis and management of patients with reported dizziness. The oculomotor evaluation during VNG utilizes video-oculography providing valuable information regarding the central structures and pathways that control eye movements. Artifact may have an effect on the overall validity and reliability of VNG oculomotor tracings and can result from patient and/or recording errors. It is postulated that artifact could occur more frequently in the pediatric population due to both patient and equipment factors.
