Percent loss, which was calculated as [1- (raw measurement / mean value of healthy eyes)]×100 (%), are shown in mean (95% confidence interval). Values with statistical significance are shown in bold. Multivariate analysis adjusted for age, gender, race, self-reported diabetes and hypertension, and scan quality.
