Significant variations have been reported concerning the size of the orbit and eyeball, and the position of the latter in the former.1 Hertel exophthalmometry has inherent deficiencies, including the fact that the lateral orbital rim (on which it relies as a reference point) varies among individuals.2 Previous studies have evaluated the position of the globe within the orbit and its correlations with MRI.3 We have also used a 1.5 T MRI scanner in a series of 32 adult patients (19 males, 59.3%) aged 56.22 (SD 13.80) (36 to 80) years, without any previous history of orbital disease, to measure the volumes of ocular and orbital structures and the distance of the eyeball poles from respective orbital landmarks. We aimed to examine whether intraorbital globe position is affected by orbital or …
