Summary
Patients with AMD and/or glaucoma who reported SAD symptoms had significantly lower vision-related quality of life scores, suggesting that moderate vision loss creates meaningful risk for seasonal mood disorders. Lighting designers and healthcare providers working with visually impaired older adults should consider SAD screening and compensatory lighting interventions to support both visual function and mental health.
Key Findings
- Patients with SAD symptoms (GSS > 8) had significantly lower vision-related quality of life composite scores compared to those without SAD symptoms (57.2 vs. 73.2, p < 0.001).
- Exploratory factor analysis identified two dimensions of the VFQ-39 that together accounted for 63.2% of total variance in the Global Seasonality Score.
- The longer VFQ-39 instrument successfully predicted SAD risk in vision-impaired patients, while the shorter, more commonly used VFQ-25 did not reliably identify at-risk patients.
- Study sample included 111 patients with AMD and/or primary open-angle glaucoma in a cross-sectional, comparative case series design.

Eye Health & Vision: Examines how moderate vision loss from glaucoma and macular degeneration correlates with SAD symptoms and quality of life.
Dementia & Elder Care: Population studied is predominantly elderly patients with age-related conditions, relevant to elder care planning.
