Bland-Altman plots of showing the agreement between the supine and sitting position in the combined group of young healthy subjects, older healthy subjects, and glaucoma patients. Variability is low and stable across the range of mean values.

Footnote: Overall average retinal nerve fiber layer (RNFL) thickness (Mean difference = .10, Limits of agreement; −4.47, 4.68), superior RNFL thickness (Mean difference = .016, Limits of agreement; −8.61, 8.64), and inferior RNFL thickness (Mean difference = 1.12, Limits of agreement; −10.12, 12.36). Variability is consistent for overall RNFL thickness (r = 0.09; P = 0.50), superior RNFL thickness (r = 0.05; P = 0.70), inferior RNFL thickness (r = 0.17; P = 0.20).
