the 95th percentile of the absolute distance were measured. Analyses were performed in IBM SPSS Statistics 22.0 (IBM Corp, Armonk, NY). A p value less than 0.05 was considered statistically significant.
Results
The study sample was composed of 50 men and 50 women who had a C mean age of 57 years (SD 18 yr.; range, 18 to 93 yr.). 3
Orbital volume
The mean orbital volume of the 200 orbits was 27.53 ± 3.11 mL. The mean volume of the right orbital cavity was 27.56 ± 3.11 mL and the mean volume of the left orbit was 27.50 mL ± 3.13 mL. The mean absolute difference between the right and left cavities was 0.44 ± 0.31 mL. The maximum absolute volume difference was 1.65 mL or 5.81 %. The minimum orbital volume was 20.20 mL and the maximum orbital volume was 37.55 mL. The paired t test showed a high correlation (0.985) and no significant difference between the left and right orbital volumes (p=0.34; Table 1).

26.29 ± 2.56 mL for the right orbital cavity and 28.74 ± 3.22 and 26.27 ± 2.52 mL for the left orbital cavity, respectively. Orbital cavities in men were significantly (p<0.05) larger than those in women (Table 2). There was no significant difference (p=0.59) in left-versus-right absolute volume between men and women.
