Video-Oculography-Based Detection of Skew Deviation in Patients Experiencing Dizziness in the Outpatient Setting: A Prospective Diagnostic Accuracy Study

Skew deviation, a vertical ocular misalignment caused by brainstem or cerebellar dysfunction, is strongly associated with central lesions in acute vestibular syndrome but has not been systematically studied in outpatient settings. This clinic-based study evaluated the prevalence of video-oculography (VOG)-guided skew deviation, its diagnostic value for posterior fossa lesions, and the accuracy of an automated VOG...

Video-oculography-based skew deviation detection may improve identification of central vestibular causes of dizziness in outpatient settings; await full results and replication before changing diagnostic protocols.

Accurately distinguishing central from peripheral causes of dizziness at first contact is a persistent clinical challenge, and objective video-oculography tools could reduce missed strokes and other serious diagnoses.

1. 01Prospective diagnostic accuracy design evaluating video-oculography for skew deviation detection.
2. 02Skew deviation is a key HINTS examination sign associated with central vestibular lesions.
3. 03Outpatient dizziness setting reflects real-world clinical conditions.
4. 04Study assesses sensitivity, specificity, or similar diagnostic metrics for the technology.
5. 05Findings could support or refine objective bedside vestibular testing protocols.
