Community-based vision health screening with on-site definitive exams: Design and outcomes

Abstract

In the U.S., the prevalence of blindness is expected to double by 2050 and as many half of those with blinding eye disease are unaware of their diagnosis. Screening for vision health in the community setting may offer a key strategy to address the rising trend avoidable vision loss. However, problems with excessive referrals and low compliance with these referrals (often <50%) undermine the effectiveness of vision screening programs. We investigated the outcomes of a modified vision screening program design. Key modifications were 1) incorporating an on-site ophthalmologist during screening events; and 2) leveraging community partner resources to maximizing benefit to participants. A review of screening outcomes of 4349 particpant examinations from the Casey Eye Institute Outreach Program (CEIO program) from 01/04/2012 to 10/3½016 were analyzed for demographics and disease findings. The burden on participants to comply with referrals was lessened as 97% of participants completed definitive exams. Clinical care was recommended for 924 (21.2%) participants. Nearly four out of five participants (78.8%) were provided care for all of their immediate vision health needs (full exams, refractions, and spectacle ordering). Modifications to vision screening program design may improve their effectiveness.
