Figure 2. Illustration of Posterior Shape Classification, Including Typical Examples and the Corresponding Diagrams.

Posterior shapes are shown in the inferior, nasal, and back views. The reconstructed optic nerve is presented to demonstrate the attachment site. The back-view diagrams are aimed at showing possible posterior protrusion(s) with dashed lines, rather than the true outline of the eye. Some eye models have been resized for demonstration purposes without affecting the shape.
