This study sought to determine if the traditional facial approximation guideline was consistent with the exophthalmometry literature.
The paper aimed to determine if there were any previously published papers that directly supported, or refuted, the facial approximation guideline for determining globe projection; and to determine if reported measures of globe projection from the lateral orbit corresponded to the tangent from the superior and inferior orbital rims as predicted by the traditional facial approximation method. MRI research showed that corneal projection was underestimated using the traditional facial approximation guideline. An underestimation was also strongly suggested by statistical comparisons of globe projection measures taken using more traditional instruments to skull morphology. The study suggests that the traditional facial approximation guideline not be used in future facial approximations since it appears to under-predict anterior globe projection by 4 mm on average.
