Abstract
 
Purpose
 

To evaluate health-related quality of life(HRQoL) in Korean adults with visual impairment(VI) using various measures and examine which sociodemographic characteristics are associated with better quality of life based on a nationally distributed sample.

 
Methods
 

Using the Korea National Health and Nutrition Examination Survey(KNHANES, 2008-2012) data, we compared EuroQol five-dimensional questionnaire(EQ-5D, www.euroqol.org) and EQ-visual analogue scale(VAS) scores after adjusting for sociodemographic and psychosocial factors as well as for comorbidities(hypertension, heart disease, stroke, arthritis, and chronic renal disease) in Korean with VI. Logistic regressions were used to elucidate determinants for the lowest quintile of HRQoL scales according to VI severity. Uncorrected visual acuity(VA) which implies vision of ordinary life was measured using an international standard vision chart based on Snellen scale.

 
Results
 

Total 28,825 participants were included in the analysis. The mean EQ-5D and EQ-VAS scores were significantly lower in the VI groups than in the normal vision(VA 20/20-20/25) group based on better or worse seeing eye(P<.0001 and P<.0001). Participants with moderate(VA 20/80-20/160) and severe VI(VA ≤20/200) had higher scores of multivariate-adjusted odd ratios (aORs) for the lowest quintile than did normal group which was particularly evident in the results from EQ-5D(aOR, 95% confidence interval (CI); 1.67(1.10-2.53) in moderate VI and 3.39(1.46-7.84) in severe VI for better eye, 1.42(1.11-1.81) in moderate VI and 1.55(1.06-2.23) in severe VI for worse eye, respectively) while the results of mild VI(VA 20/32-20/63) group did not identified significant differences from normal group. On the other hand, EQ-VAS revealed significantly higher score of multivariate-aORs for the lowest quintile in participants with mild VI either for better or worse seeing eye(aOR, 95% CI; 1.24(1.10-1.40) and 1.14(1.02-1.28), respectively).

 
Conclusions
 

The severity of VI was definitely associated with impaired HRQoL compared with the normal vision population. The analyses presented here elicited even mild VI could potentially deteriorate HRQoL(or subjective perception of health qulity) and therefore, therapeutic approaches should also focus on the subjective perception and better management of health condition.
