Association of Vision Impairment With Cognitive Decline Across Multiple Domains in Older Adults

Key Points Question Are there associations between visual and cognitive impairment across multiple cognitive domains and multiple measures of vision? Findings In this longitudinal cohort study of 1202 older adults, worse visual acuity and stereo acuity impairment were associated with greater declines in language and memory domain scores, whereas worse contrast sensitivity was associated with declines in language, memory, attention, and visuospatial ability domain scores. Meaning These findings suggest that the association between vision and cognition differs by measure of vision and that impaired contrast sensitivity is associated with declines across more cognitive domains than visual acuity.
