Correlation of bony anatomic parameters (distances) to globe position values.
Table 6.
Correlations of angle measurements to globe position.
Hertel values were defined as: Ga-CorparaMlo and Fms-CorparaGa.
Table 7.
Results for distances in derived from previous studies.
Mean Orbit Volume is given in ml, Mean Orbit Surface in cm2, all further parameters are in mm. Studies on non-Caucasian groups are marked “*”.

Results for angles for comparison from previous studies.
Fig 3.
Visualization of anatomic parameters defining globe position measurements.
An increase of the displayed distances (as stated in red arrows) anterior to the orbital aperture will lead to increased Hertel values, whereas an increase of distances within the orbit will lead to larger distances of the globe to the orbital apex. Analysis planes (parallel planes to Cor through Da, SupM, and AO are visualized as blue lines).
