Summary
Both self-reported and performance-based visual impairment (VI) are linked to reduced lower extremity physical function in older adults. This highlights a need for targeted screening and interventions for those with combined visual and physical challenges.
Area of Science:
- Gerontology
- Ophthalmology
- Physical Therapy
Background:
- Visual impairment (VI) is a growing concern in aging populations.
- The relationship between different types of VI and physical function requires further investigation.
Purpose of the Study:
- To assess the association between self-reported and performance-based measures of visual impairment and lower extremity physical function in older adults.
Main Methods:
- Cross-sectional analysis of 2,219 participants from the Health ABC study.
- Utilized linear regression models to predict the Short Physical Performance Battery (SPPB) using self-reported visual function (VFQ) and performance-based vision tests (VA, LCS, SA).
Main Results:
- All visual impairment measures were significantly associated with lower SPPB scores (p < .001).
- Log contrast sensitivity (LCS) showed the strongest association with SPPB, even after adjusting for covariates.
- Stereoacuity (SA) was independently associated with balance, a component of SPPB.
Conclusions:
- Both self-reported and performance-based visual impairment are strongly linked to poorer physical function in older adults.
- Findings suggest a subgroup of older adults with co-existing visual and physical dysfunction who may benefit from targeted interventions to prevent disability.
