Samenvatting

Objectives: To assess visual acuity (VA) while the patient is walking and to evaluate oscillopsia severity in patients with bilateral vestibulopathy (BV) and in patients with unilateral vestibular loss (UVL). Design: Prospective study with a group of patients with BV, a group of patients with UVL, and a control group of healthy subjects. Setting: Tertiary academic center. Participants: Thirty seven patients with BV(age range, 29-80 years), 11 patients with UVL (age range, 48-75 years), and 57 healthy subjects (age range 20-77 years). Intervention: Computation of the difference between the VA measured in static conditions and in dynamic conditions while walking on a treadmill at 2, 4, and 6 km/h. Oscillopsia severity was assessed with a questionnaire that we developed. Main Outcome Measures: Differences in VA at 2, 4, and 6 km/h and oscillopsia severity score. Results: As a group, patients with BV showed a significant increase of the VA differences compared with healthy subjects (P.05 for all comparisons). Conclusions: We designed a highly sensitive, simple, cost-effective protocol to assess dynamic VA under physiologic conditions and a questionnaire to determine oscillopsia severity. Both tools could be used for the evaluation of new treatments for BV and patients with UVL
