Quality of life associated with visual loss: a time tradeoff utility analysis comparison with medical health states.
OBJECTIVE
To assess the visual utility values of patients with ocular disease and to compare these values with those of patients with systemic health states


METHODS
Cross-sectional utility value assessment.


METHODS
Consecutive patients with ophthalmic diseases were interviewed in a one-on-one fashion using a standardized time tradeoff utility value assessment form. These values were compared with utility values for systemic health states present in the literature.


METHODS
None.


METHODS
Time tradeoff utility value on a scale ranging from 1.0 (perfect visual health) to 0.0 (death). The ophthalmic patient groups were stratified into 4 visual groups dependent on the visual acuity in the better-seeing eye. The groups were as follows: group 1, 20/20 to 20/25; group 2, 20/30 to 20/50; group 3, 20/60 to 20/100; group 4, 20/200 to no light perception.


RESULTS
A total of 500 subjects were enrolled in the study. The mean utility values for the visually stratified groups were: group 1, 0.88; group 2, 0.81; group 3, 0.72; group 4, 0.61. Comparable respective systemic health state utility values for each of the ophthalmic groups were: diabetes mellitus, status after kidney transplantation, moderate stroke, and moderately severe stroke.


CONCLUSIONS
Visual loss is associated with a substantial and measurable diminution in quality of life. This diminution in quality of life can be directly compared with that induced by systemic health states.
