Resumo: | <p><b>OBJECTIVE:</b> To investigate the importance of improving visual assessment for community-dwelling older adult fallers.<br> <b>METHODS:</b> Cross-sectional study with eligible older adults (> 60 years old) living in the community and who suffered at least one fall in the last 12 months from the PrevQuedas Brasil clinical trial. Sociodemographic data, information on previous falls, physical and functional assessment (BOMFAQ and FES-I) were collected. We evaluated impairments in visual acuity and contrast sensitivity using the Snellen E chart and low-contrast visual acuity tests, respectively. Dual visual impairment refers to the presence of both impairments. For statistical analysis we compared the participants in relation to the number of falls (single fallers or recurrent fallers) using Chi-square or Fisher's exact test and the significance level was <0.05 for all analyses.<br> <b>RESULTS:</b> Visual acuity, low contrast sensitivity, and dual visual impairment were associated with recurrent falls (OR 1.85); visual impairment was more prevalent among the oldest old. Approximately 90% of the participants reported using glasses, and 63.80% used multifocal lenses. Dual impairment was identified in 143 (20.30%) participants. In multivariate logistic regression, the predictive variables for recurrent falls were low contrast sensitivity (95%CI 1.15–2.47), dual visual impairment (95%CI 1.16–2.83), and self-perceived fall risk (95%CI 1.16–2.46) which was measured using the Falls Efficacy Scale-International.<br> <b>CONCLUSION:</b> Older adults with dual visual impairment are more likely to suffer recurrent falls. Low contrast sensitivity is crucial for fall risk assessment.<br> <b>Trial registration:</b> ClinicalTrials.gov (NCT01698580).</p> |
