Vision and independence in older adults

Characterizing Vision Impairment and Its Impact on Independence in Older Adults

NIH-funded research Univ of North Carolina Chapel Hill · NIH-11259578

What this research studies

You would have simple vision tests done at home that measure distance clarity and contrast sensitivity (how well you see in low light or low-contrast situations). The team will add these tests to a one-time home visit for about 4,200 women who have been followed in the Women’s Health Initiative for decades. They will combine the vision results with years of health, cognitive, social, and physical function information to describe how common vision problems are and how they relate to independence and well-being. The focus is especially on the oldest participants (age 80+), and the study will note how many problems are correctable, like needing glasses or cataract treatment.

Who could benefit from this research

Good fit: Ideal candidates are older women already in the Women’s Health Initiative (especially those age 80 and older) who can receive an in-home visit and complete simple vision tests.

Not a fit: Men, younger adults, or people not part of the WHI home-visit group are unlikely to be eligible or directly benefit from joining this specific study.

Why it matters

Potential benefit: If successful, this work could reveal common, treatable vision problems in very old adults and point to ways to help people stay safer and more independent.

How similar studies have performed: Previous studies have documented uncorrected refractive error and cataracts as common and treatable in older adults, but few large population studies have measured contrast sensitivity in the oldest-old, so parts of this work are relatively novel.
