GLOBE-RIM RELATIONS
■The relationship of the globe to the orbital rims is a primary determinant of the appearance of the upper third of the face.
■On average, the surface of the soft tissues overlying the supraorbital rim lies 10 mm anterior to the cornea, and the surface the soft tissues overlying the infraorbital rim lies 3 mm behind the anterior surface of the cornea. This implies that the supraorbital rim usually projects 13m beyond the infraorbital rim.
■When the orbital rims have a greater projection beyond the anterior surface of the cornea, the eyes appear deep set.
■When the orbital rims project less, the eyes appear prominent. In addition to being predisposed to corneal exposure related problems, overly prominent eyes are usually considered less attractive.
■Globe to orbital rim measurements have a wide range and are influenced by ethnicity and sex, and change with aging.
