Agreement between angle-to-angle and corneal diameter measurements.
Bland-Altman plots depicting the agreement between (A) horizontal corneal diameter (CD) and horizontal angle-to-angle (AA) measurements; (B) vertical CD and vertical AA measurements. The solid line represents the mean difference (bias), and the dotted lines represent 95% LoA.

Linear relationship between angle-to-angle and corneal diameter.
Regression plots depicting the relationship between corneal diameter (CD) and angle-to-angle (AA) measurements for: (A) horizontal and (B) vertical measurements for all eyes, where subject age is represented by shade, with darker shades corresponding with older children; (C) horizontal and (D) vertical measurements for healthy control subjects; (E) horizontal and (F) vertical measurements for subjects with glaucoma.
