To understand if visual function tests with moving stimuli were harder to process and caused more symptom provocation in persistent postural perceptual dizziness (PPPD) patients compared with those with other vestibular diagnoses or without any vestibular symptoms.

Discussion
Signed responses from readers of the wire.
Visual motion sensitivity tests may help clinicians identify and differentiate PPPD in pediatric and young adult patients, but replication in larger samples is needed before changing diagnostic protocols.
Establishing objective visual-function markers for PPPD in younger populations could improve earlier diagnosis and guide vestibular rehabilitation targeting visual dependence.
- 01Prospective controlled design compared PPPD patients to healthy controls in children and young adults.
- 02Moving-stimuli visual function tests provoked significantly more symptoms in the PPPD group.
- 03Findings support visual motion hypersensitivity as a measurable characteristic of pediatric/young-adult PPPD.
- 04Results may inform selection of vestibular rehabilitation strategies targeting visual desensitization.
- 05Sample size and single-center design limit immediate generalizability.
Visual function tests with moving stimuli cause greater symptom provocation in children and young adults with PPPD compared to healthy controls.
