Abstract

Purpose: It is widely known that visual impairment (VI) is a risk factor for falls, but patients or their eye care practitioners may not recognize other kinds of incidents as being problematic because of their vision. Consequently, older people with VI may have unmet needs for advice on how to carry out activities of daily living safely. Therefore, the purpose of this study was to understand whether older people with VI consider their vision as a causative factor of incidents they experience and their perceptions regarding the prevention of future incidents. If sample size permitted, a secondary aim was to evaluate whether quantitative findings supported their perceptions. Methods: The study design was a prospective cohort study evaluating injurious and damaging incidents and related near misses using open questions in a written 2-weekly large-print diary with active follow-up over 8 weeks in older people (960 years, n = 80) with and without VI. Baseline measures included habitual binocular visual acuity, contrast sensitivity, visual fields, 3-m walk test, and Short Form 12 physical and mental component scores. Participants' diary entries were coded. Factor analysis and binary logistic analysis were used to investigate whether baseline measures were predictive of incident occurrence. Risk and preventative factors identified were compared. Results: Participants perceived that their vision was implicated in bump and fall incidents. Quantitative analysis indicated that contrast sensitivity and fitness were significant predictors of incident occurrence. Six vision-related and five nonYvisionrelated causative factors were identified by participants as contributing factors. Participants frequently stated "don't know" when asked to identify solutions to prevent incident recurrence. Conclusions: Participants had unmet needs for advice in relation to incident prevention. It would be prudent for eye care practitioners to raise incident prevention in eye care consultations regardless of voiced patient concerns.
