The purpose of this study was to examine the development of the orbit in Hong Kong Chinese subjects. Orbit volume was determined from magnetic resonance images of 81 subjects aged from 1 to 42 years old. Results show that orbit volume ranged from 11.56 to 25.50 cm3. In the first year of life, the mean orbit volume was 12.36 cm3. The orbit showed rapid growth in the first 3 years of life. From about 1-3 years old, the mean volume was 15.31 cm3. The orbit grew steadily to the age of 10 years. From age 11 to 15 years old, the mean volume was 20.24 cm3. Orbit growth levelled off at about 16 years of age with the mean volume at 21.00 cm3.
本研究的目的是探讨香港华人受试者眼眶的发育情况。通过对81名年龄在1至42岁之间的受试者的磁共振图像测定眼眶容积。结果显示，眼眶容积范围为11.56至25.50立方厘米。在生命的第一年，平均眼眶容积为12.36立方厘米。眼眶在生命的前3年显示出快速生长。从大约1至3岁，平均容积为15.31立方厘米。眼眶稳定生长至10岁。从11岁到15岁，平均容积为20.24立方厘米。眼眶生长在大约16岁时趋于平稳，平均容积为21.00立方厘米。
