Abstract summary 

This cross-sectional study investigated the health-related and vision-related quality of life measures of adults with low vision compared to healthy individuals in Trinidad and Tobago. The health-related quality of life (HRQOL-14) and the National Eye Institute Visual Functioning Questionnaire (NEI-VFQ-25) were administered to 20 participants with low vision caused by diabetic retinopathy, retinitis pigmentosa, glaucoma, and macular degeneration, as well as 20 participants with no visual problems (control). Participants were recruited from the University Eye Clinic in Trinidad and Tobago. Compared to the controls, more participants in the low-vision group had lower age-adjusted NEI-VFQ-25 scores (48.3% vs. 95.1%; < 0.001), had poor general (47.5% vs. 10%, = 0.004) and mental (100% vs. 10%, < 0.042) health, experienced greater activity limitation due to impairment or health problems (85% vs. 20%, < 0.001), needed help with personal care (27.5% vs. 0%, < 0.009) and daily routine (67.5% vs. 0%, < 0.001), and experienced sleep problems (97.5% vs. 65%, < 0.001) and symptoms of anxiety (100% vs. 90%, = 0.042). All the diabetic retinopathy participants (100%, = 0.028) had two or more impairments or vision problems compared to none in the other low-vision participants. In summary, the HRQOL-14 and NEI-VFQ-25 scores were significantly reduced in low-vision participants, who also demonstrated a greater vulnerability to poor quality of life in the presence of diabetes retinopathy. These findings have important clinical implications regarding offering appropriate support and interventions to improve quality of life outcomes in individuals with low vision.
