“…Additionally, the average TOFV increased as age increased. This is in contrast with the speculation of Ahmadi et al (22) that the orbital adipocytes undergo atrophy with advancing age. The significant correlation of age with TOFV may be attributable to a relative reduction in muscular bulk and volume of the globe itself with increasing age (23,24).…”

Abstract. The aim of the present study was to examine the total orbital volume (TOV) and total orbital fat volume (TOFV) in normal orbits in different age groups and to investigate the correlation of these measurements with age, gender and body parameters by magnetic resonance imaging (MRI). MRI data were acquired retrospectively from a total of 1,453 subjects divided into five age groups with 10-year intervals. The TOV and TOFV were measured using T1-weighted MRI for each subject and body parameters were also obtained. The measurements demonstrated that TOV increased with age and that the volume was larger in men than in women. While weight and height exhibited positive correlations with TOV in male and female subjects in the 20-29, 30-39 and 40-49-year-old age groups, only weight showed a positive correlation with TOV in female subjects in the 50-59 and 60-69-year-old age groups. However, TOFV increased by age in all groups and the increments were larger in women than in men. These results provide basic information about the effect of age, gender and body parameters on TOV and TOFV. The variations in TOV are associated with orbital soft-tissues changes rather than with TOFV.

“…A similar conclusion has been reached with several studies using computed tomography for the evaluation of globe position with aging. [13][14][15] Interestingly, in a study conducted by means of exophthalmometry by Ahmadi et al, 16 a linear reduction in ocular protrusion with increasing age was noted. The findings on exophthalmometry appear to be different from the studies conducted with computed tomographic scanning, possibly because most studies conducted with computed tomography measure the anterior and posterior globe ratio instead of direct numerical length of the anterior ocular protrusion.…”

“…There are significant differences in orbit shape and size, as well as eye placement, between persons of different gender, age, and ethnicity (Ahmadi et al, 2007;Barretto and Mathog, 1999;Bolanos Gil de Montes et al, 1999;Dunsky, 1992;Pessa and Chen, 2002;Pessa et al, 1999;Pivnick et al, 1999;Pryor, 1969;van den Bosch et al, 1999). These anthropometric differences are suspected to affect the response of the eye when subjected to a traumatic impact.…”
