Objective:

To evaluate the association between major eye diseases and loneliness scores in patients with diagnosed ocular conditions.

Approach:
  • Study Design: Cross-sectional analysis of 61,349 patients from the NIH All of Us cohort who completed the UCLA Loneliness Scale.
  • Participants: Patients with at least one diagnosed ocular condition, excluding those without a history of eye care.
  • Outcome Measures: Primary outcome was a UCLA Loneliness Scale score above the cohort median, adjusted for various sociodemographic factors.
Key Findings:
  • Self-reported blindness was associated with 1.61 times the odds of high loneliness scores in adjusted analyses.
  • Diabetic retinopathy was associated with high loneliness scores in adjusted analyses, with proliferative diabetic retinopathy at 1.28 times and nonproliferative at 1.16 times the odds.
  • No association was found between glaucoma or age-related macular degeneration and high loneliness scores after adjustment.
Interpretation:

The association between diabetic retinopathy and loneliness may reflect factors beyond vision loss alone, potentially related to systemic health outcomes of diabetes.

Limitations:
  • Cross-sectional design limits causality determination.
  • Blindness assessed by self-report rather than structured visual acuity measures.
  • Cohort predominantly White, which may limit generalizability.
  • Potential selection bias may also be present.
Conclusion:

Loneliness was associated with self-reported blindness and diabetic retinopathy but not with glaucoma or age-related macular degeneration.
