Relationship of nasolacrimal duct with apex of large upper incisor (labelled)

This skull is from a wild rabbit. Part of the bony canal that encloses the nasolacrimal duct has been removed to expose the duct within it. The duct bends medially at the apex of the large upper incisor. Only a small amount of apical elongation would compress the duct at that point.
