Figure 2.

Results of the 3D segmentation with anatomic parameters of the eyeball. Data were obtained from a T2-weighted 3D scan of the eyes looking at a target at central position between the eyes and 143 cm away. A, NGM was used to analyze anatomic properties like eyeball diameter and relative orientation of cornea and lens of both eyes of each participant. B, Axial and sagittal slices of both eyes of P1 with segmentation of sclera (orange), cornea (blue) and lens (green). C, Same for P2. Although both participants fixated the same target, the physical orientation of the eyes noticeably differs. For better illustration, we show the line connecting eyeball center and visual target in red and the line passing through eyeball and cornea center, as a proxy for physical orientation of the eye, in blue.
