Persistent postural-perceptual dizziness (PPPD) patients with visual dependency rely more on visual cues and may have altered oculomotor responses to visual motion. This study examined early eye movement responses to large-field motion stimuli-the ocular following responses (OFRs)-in 30 PPPD patients and 29 healthy controls....

Discussion
Signed responses from readers of the wire.
Early oculomotor (eye movement) responses to visual motion may serve as a measurable marker of visual dependency in PPPD, but clinical use of this finding requires further validation; no change to current PPPD assessment or treatment protocols is warranted yet.
Objective eye-movement biomarkers for PPPD could improve diagnosis of this often-misunderstood chronic dizziness condition and help target vestibular rehabilitation strategies.
- 01Patients with PPPD show altered early oculomotor (eye movement) responses to visual motion stimuli.
- 02The findings support the concept of heightened visual dependency in PPPD.
- 03Objective eye-movement measures could supplement subjective symptom reports in PPPD diagnosis.
- 04Study published in Annals of the New York Academy of Sciences.
- 05Results are preliminary and require replication in larger, controlled samples.
Patients with PPPD exhibit early oculomotor responses to visual motion that differ from those without the condition, reflecting visual dependency.
