Abstract

OBJECTIVE

An evaluation of orbital development in children from birth to 6 years of age was conducted in order to provide normal reference values for clinical use.

METHODS

Retrospective cohort study. By combining multi-section helical computerized tomography (CT) imaging with a computer-aided design system (BrainLAB, Munich, Germany; iPlan Cranial Software, version 2.5), we measured the orbital volume of 100 emergency children (200 eyes), who underwent computerized tomography (CT) scanning due to mild injury in Beijing Tongren Hospital and had normal CT findings. From birth to 6 years of age, according to the age of < 1 years of age for the treatment of 0 year old group, aged 1 years old and < 2 years old for 1 year old group, and so on, divided into 7 groups. Among the 50 male and female patients, the ages are 0-6 years. All of these were in order to analyze the relationship between the age and orbital volume with unary linear correlation and regression. The comparison of orbital volume between females and males was performed using two independent t-tests. Comparisons of bilateral orbital volumes were performed using a paired t-test.

RESULTS

The average orbital volume of children was initially (12.57 ± 3.80) cm(3) at birth, and then increased to (19.34 ± 1.86) cm(3) at 6 years of age, with an average annual growth of 1.13 cm(3). There was a positive linear relationship between orbital volume and age in children from birth to 6 years of age, yielding the regression equation: Y (orbital volume) = 13.582 + 1.042 × X(age). There is no statistic difference on the orbital volume between boys and girls (t = 1.073, 0.533, 1.808, 1.039, 1.346, 0.983, 1.774, P > 0.05). In addition, no statistic difference was found between the left and right orbital volume (t = 1.059, P = 0.292). The growth curves for all groups almost overlapped with each other.

CONCLUSIONS

There is a positive linear relationship between orbital volume and age in children from 0 to 6. The bilateral orbital volumes were almost the same. There is no statistic difference on the orbital volume between boys and girls.

摘要

目的

对出生至6岁儿童的眼眶发育情况进行评估，以便为临床提供正常参考值。

方法

回顾性队列研究。通过将多层螺旋计算机断层扫描（CT）成像与计算机辅助设计系统（德国慕尼黑BrainLAB公司；iPlan Cranial软件，2.5版本）相结合，我们测量了100例急诊儿童（200只眼）的眼眶容积，这些儿童因轻度损伤在北京同仁医院接受了计算机断层扫描（CT），且CT检查结果正常。从出生至6岁，按年龄<1岁为0岁组，1岁≤年龄<2岁为1岁组等，分为7组。50例患者中男女均有，年龄为0 - 6岁。所有这些都是为了用一元线性相关和回归分析年龄与眼眶容积之间的关系。采用两独立样本t检验比较男女眼眶容积。采用配对t检验比较双侧眼眶容积。

结果

儿童眼眶平均容积出生时最初为（12.57±3.80）cm³，6岁时增至（19.34±1.86）cm³，平均每年增长1.13 cm³。出生至6岁儿童眼眶容积与年龄呈正线性关系，得出回归方程：Y（眼眶容积）=13.582 + 1.042×X（年龄）。男孩和女孩眼眶容积无统计学差异（t = 1.073、0.533、1.808、1.039、1.346、0.983、1.774，P>0.05）。此外，左右眼眶容积无统计学差异（t = 1.059，P = 0.292）。所有组的生长曲线几乎相互重叠。
