Visual impairment (VI) causes a considerable public health burden and substantial deterioration in health-related quality of life (HRQoL). However, the relative effect of VI on HRQoL compared with other chronic health conditions is unknown as is the additive effect of VI with other conditions. ⋯ These results suggest that VI has a substantial effect on HRQoL, even in the presence of concurrent chronic health conditions, and the combined effect of VI and stroke, osteoarthritis/rheumatic arthritis, hepatitis, or depression on HRQoL was greater. However, because this study group was a representative sampling of South Koreans, generalization to other races/ethnicities and countries should be approached with caution.
