In this paper we present a scoping review of literature on aging, visual impairment, and physical activity. Our objectives are to: (a) explore the available literature on aging, physical activity, and sight loss; (b) describe how participation in physical activity by older adults with visual impairment is understood by researchers; and, (c) identify benefits, barriers, and facilitators of physical activity participation as reported by older adults with age-related sight loss. Over 2,000 sources were reviewed, with 30 studies meeting eligibility criteria. Findings were organized into four thematic categories, namely: (a) participation rates; (b) health inequalities; (c) barriers to physical activity participation; and, (d) benefits of physical activity participation. Through this scoping review process, extant knowledge was synthesized and gaps in the literature were critically assessed. To address these gaps, several avenues for future research are outlined and described, alongside a consideration of the implications of the scoping review findings for both policy and practice.
