A Novel Three-Dimensional Vector Analysis of Axial Globe Position in Thyroid Eye Disease

Figure 3

Bland-Altman plots compared the results of Hertel exophthalmometer and CT measurement. The left one showed the difference between the Hertel results and the coordinate x_E of , and the right one showed the difference between the Hertel results and 2D CT exophthalmos. It could be found that the difference between the Hertel results and 2D CT exophthalmos was more dispersed than that between the Hertel results and x_E and had much fewer plots within −1~1 mm.
