IMPORTANCE: The ocular status of homeless populations remains largely unknown. Given that visual acuity has been shown to be heavily correlated with reduced well-being and decreased earning potential, findings of poor vision could have important health implications for people experiencing homelessness.
OBJECTIVES: To assess the prevalence of visual impairment and to identify unmet eye care needs in an adult homeless population.
DESIGN, SETTING, AND PARTICIPANTS: For this cross-sectional study, we recruited 100 homeless persons using a stratified random sampling technique from January to March 2014. Recruitment took place at 10 randomly selected adult shelters in Toronto, Ontario, Canada. All English-speaking persons older than 18 years of age were eligible to participate. Information was obtained on sociodemographic characteristics, ocular history, and subjective visual acuity. A comprehensive vision screening and an undilated retinal examination were performed for each participant.
MAIN OUTCOMES AND MEASURES: Rates of functional visual impairment and prevalence of nonrefractive eye pathology.
RESULTS: The median age of participants was 48 years (interquartile range, 36-56 years), and 62% were men. The median lifetime duration of homelessness was 12 months (interquartile range, 5-36 months). Based on the participants' presenting visual acuity, the age-standardized rate of visual impairment was 25.2% (95% CI, 16.7%-33.7%). After pinhole occlusion, this number decreased to 15.2% (95% CI, 7.7%-22.7%). In total, 13.0% (95% CI, 7.8%-20.0%) of participants experienced visual impairment secondary to a correctable refractive error. Although the major problem for this demographic was limited access to refractive correction, a large degree of nonrefractive pathology was also observed. Of all the participants, 34.0% (95% CI, 24.7%-43.3%) had 1 or more abnormal findings during the vision screening, and 8% (95% CI, 2.7%-13.3%) required urgent referral to an ophthalmologist. A large majority of participants (89.0%) indicated interest in accessing free eye examinations.
CONCLUSIONS AND RELEVANCE: These data suggest that homeless adults have a high prevalence of visual impairment, even when living within a system of universal health insurance. Given the high level of interest in eye care among homeless persons, ongoing vision-screening programs and readily accessible free eye clinics may help address this need.
