Evaluation of Nystagmus Examination Using Wearable AR Glasses in Vertigo Patients

Background and Purpose: Vertigo is common in emergency and outpatient settings, yet standard oculomotor testing usually requires dedicated equipment and exam rooms. This study evaluates whether nystagmus examinations performed with wearable augmented-reality (AR) glasses are equivalent to conventional examination-room testing for classifying central vs. peripheral vertigo. The investigators also assess diagnostic accuracy, patient tolerability, and the reliability of AR-based interpretation (test-retest and inter-rater). Study Design: Prospective, single-center, within-subject randomized equivalence study at Kaohsiung Chang Gung Memorial Hospital. Each participant completes both AR-based and conventional oculomotor testing in a randomized order during the same visit, separated by a 30-minute washout. The study uses an evaluator-blind approach: de-identified trajectories are reviewed offline by independent experts who are masked to test modality. A follow-up visit (\~1 week) captures adverse events and patient experience. Participants: Adults (≥18 years) presenting with vertigo who can tolerate the AR headset and provide consent. Key exclusions include conditions that prevent reliable eye-tracking (e.g., corrected visual acuity \<20/40), recent use of vestibular suppressants (within 24 hours), and other factors limiting cooperation or safety. Interventions and Procedures: The AR system records eye movements and presents standardized visual stimuli. Conventional testing …
