Objectively Measured Visual Impairment and Dementia Prevalence in Older Adults in the US.

ABSTRACT:

Importance

Estimates of the association between visual impairment (VI) and dementia in the US population are based on self-reported survey data or measures of visual function that are at least 15 years old. Older adults are at high risk of VI and dementia so there is a need for up-to-date national estimates based on objective assessments.

Objective

To estimate the association between VI and dementia in older US adults based on objective visual and cognitive function testing.

Design, setting, and participants
