Auxilury line Measuring method

Meaning Views

LP An axis was drawn which passed the cornea and the center of the optic canal. The perpendicular axis was placed on the edge of the lateral orbital rim

the cornea to the intersection

eye protrusion relative to the lateral orbital rim

axial view

SP A line was drawn from cornea through the center of the eyeball, meanwhile another line was made to connect the superior and inferior orbital rim.

the intersection to the cornea

eye protrusion relative to the superior orbital rim
