Relationship between fear of falling and mobility varies with visual function among older adults.

Aim: The present study examined the association between vision, fear of falling and fear-related activity restriction, and assessed the effect of vision on the relationship between fear of falling and mobility, using data from a nationally representative sample of community-dwelling adults aged ≥ 50 years.

Methods: Participants (n=5003) completed an interview and health assessment (including Timed Up-and-Go, vision and cognitive tests). Visual acuity and contrast sensitivity were assessed using an Early Treatment Diabetic Retinopathy Study logMAR chart and Functional Vision Analyzer, respectively.
