Linear regression plot of NEI-VFQ-25 composite scores and visual field loss (Mean Deviation scores in decibels) in better seeing eye. The NEI- VFQ-25 composite scores are adjusted for co-variates including age, gender, education, employment status, income, acculturation, co-morbidities, health insurance, vision insurance, and visual acuity impairment. The mean deviation-specific data of all persons by each unit of mean deviation of visual field loss were plotted to show the independent relationship of visual field loss with vision-specific quality of life.
