“…In this study, the mean OV of Chinese adult males was 22 ± 2.2 cm 3 , which was significantly higher than that of females (20 ± 1.5 cm 3 ). Previous studies have demonstrated that the OV data in Asians, such as Hong Kong people in China (male: 22 ± 1.4 cm 3 ; female: 20 ± 2.2 cm 3 ) [10] and Koreans (22 ± 1.7 cm 3 for men and 19 ± 1.8 cm 3 for women) [11], were similar to ours. However, among Caucasians, the OVs (29 ± 2.4 cm 3 for males and 25 ± 2.2 cm 3 for females) [7] were greater than those for the population in this study.…”

Quantitative measurement of the orbital soft tissue volume plays a very important role in the study of orbital diseases. The purpose of this study is to establish a computed tomography- (CT-) based three-dimensional (3D) reconstruction model and measure the orbital soft tissue volume in Chinese adults. We collected data from 103 Chinese adults (52 males and 51 females) who underwent orbital CT. The CT images of these adults were used to reconstruct a 3D model of the orbital bony cavity, orbital fat, extraocular muscle, and intraorbital optic nerve using Mimics software, and their respective volumes were measured. The mean (±SD) orbital bony cavity volume (OV), orbital fat volume (FV), extraocular muscle volume (MV), and intraorbital optic nerve volume (iONV) of the males were 22.2 ± 2.2 cm3, 8.9 ± 1.8 cm3, 1.9 ± 0.34 cm3, and 0.41 ± 0.08 cm3, respectively. The mean OV, FV, MV, and iONV of the females were 20.2 ± 1.5 cm3, 8.1 ± 1.7 cm3, 1.6 ± 0.3 cm3, and 0.36 ± 0.074 cm3, respectively, which were all significantly lower than those in males (all p<0.05). FV (r = 0.370; p<0.001) and MV (r = 0.283; p=0.007) were significantly correlated with body mass index (BMI), while iONV was not correlated with BMI (r = −0.070; p=0.480). This study shows that FV, MV, and iONV were higher in males than in females. With increasing BMI, FV and MV both increased, but iONV did not exhibit this trend.

“…Similar gender variation was noted in other studies [1,5,[12][13][14][15][16][17][18]. Bentley et al [10] used MRI to measure OV of mainly Caucasians and found that OV was larger in British children compared to Saudi children.…”

Purpose: To provide age and gender-specific reference values of bony orbital volume in normal healthy eyes of Saudi Arabian children. Methods:A retrospective review of health data was performed between October 2014 to May 2015. Healthy eyes of children aged 15 years or younger without orbital disease were included. Their computed tomography (CT) scans were reviewed. Orbital bony cavity volume (OV) was calculated by the 3D-semiautomated volumetric methods. Variation of OV by age and gender was analyzed. Results Conclusion:OV of normal healthy eyes of Saudi Arabian children statistically significantly differed between gender and with age. The 3D volumetric method presents a reliable method for orbital volumetry. The rapid phase in orbital growth in Saudi males and females seems to end at 15 years and 11 years old respectively. Advances in Knowledge:Orbital volume (OV) of 374 Saudi children measured by semiautomatic method (CT scan) was 19.1 mm 3 . The OV of boys was larger than of girls. With increasing age, the OV increased but in different proportions in boys and girls.

“…One CT study on Chinese patient conducted by Ji, et al defined an anterior limit including the entire globe and eyelid tissue [ 7 ]. Possibly due to the extra-orbital contents, their results approximated those of Caucasian populations (28.41±2.09 ml) and were higher than a number of studies in Asian populations ( Table 3 ) [ 6 , 8 , 9 , 21 ]. The study on Hong Kong Chinese patients by Chau et al utilized MRI images for orbital volume calculation.…”

3D-Assisted Quantitative Assessment of Orbital Volume Using an Open-Source Software Platform in a Taiwanese Population

et al. 2015

Orbital volume evaluation is an important part of pre-operative assessments in orbital trauma and congenital deformity patients. The availability of the affordable, open-source software, OsiriX, as a tool for preoperative planning increased the popularity of radiological assessments by the surgeon. A volume calculation method based on 3D volume rendering-assisted region-of-interest computation was used to determine the normal orbital volume in Taiwanese patients after reorientation to the Frankfurt plane. Method one utilized 3D points for intuitive orbital rim outlining. The mean normal orbital volume for left and right orbits was 24.3±1.51 ml and 24.7±1.17 ml in male and 21.0±1.21 ml and 21.1±1.30 ml in female subjects. Another method (method two) based on the bilateral orbital lateral rim was also used to calculate orbital volume and compared with method one. The mean normal orbital volume for left and right orbits was 19.0±1.68 ml and 19.1±1.45 ml in male and 16.0±1.01 ml and 16.1±0.92 ml in female subjects. The inter-rater reliability and intra-rater measurement accuracy between users for both methods was found to be acceptable for orbital volume calculations. 3D-assisted quantification of orbital volume is a feasible technique for orbital volume assessment. The normal orbital volume can be used as controls in cases of unilateral orbital reconstruction with a mean size discrepancy of less than 3.1±2.03% in females and 2.7±1.32% in males. The OsiriX software can be used reliably by the individual surgeon as a comprehensive preoperative planning and imaging tool for orbital volume measurement and computed tomography reorientation.
