Abbreviations: NEI-VFQ, National Eye Institute Visual Function Questionnaire.
Sample sizes for driving, general vision, and color vision subscales are lower owing to missing responses. Better-eye means the better-seeing eye.
Mean 25-item NEI-VFQ subscale scores have been previously published.3 Mean overall 25- and 37-item NEI-VFQ scores and mean 37-item subscale scores have not been previously published (Carol Mangione, MD, unpublished data, April 19, 2002).
The same number of items contribute to the subscales in the 25- and 37-item NEI-VFQ.
