VEOG
Pronunciation: VEE-og
Also written as: VEOG — Vertical Electrooculography
Vertical electrooculography recording that monitors vertical eye movements to identify ocular artifacts in EEG.
Full Definition
VEOG (Vertical Electrooculography) is a specialized recording technique that captures vertical eye movements by placing electrodes above and below the eye or using a superior orbital electrode referenced to an earlobe. This monitoring is essential in EEG interpretation as vertical eye movements create characteristic artifacts that can mimic epileptiform activity, particularly in frontal and frontopolar channels. VEOG helps differentiate true cerebral activity from ocular artifacts, especially important when evaluating suspected frontal lobe seizures or when patients have frequent eye movements during recording.
Usage
Usage note: Always spell out on first use in formal reports: vertical electrooculography (VEOG).
In Context
- "VEOG channels clearly demonstrated that the rhythmic activity in Fp1 was artifactual due to vertical eye movements." — Artifact identification report
- "The technologist added VEOG monitoring to better characterize the patient's frequent blinking." — Technical procedure note
