Abstract

PURPOSE

The aim of this paper was to describe the development of the human eyeball and orbit during fetal life.

MATERIAL AND METHODS

Eighteen human fetuses (36 eyes and 36 orbits) with gestational age ranging from 17 to 28 weeks were examined. Fetuses died in the first hours of life due to immaturity and did not reveal any developmental anomalies. The axial and equatorial diameters of the eyeballs as well as the depth and width of the orbits were measured. The data was analyzed statistically with Student's t-test and Pearson's correlation coefficients.

RESULTS

It was found that the axial length (p < 0.005) and equatorial diameter (p < 0.001) of the eyeballs, as well as the depth (p < 0.001) and width (p < 0.001) of the orbit increase with age. Furthermore, growth of the axial length of the eye is paralleled by increase in orbital depth (p < 0.001) while growth of the equatorial diameter coincides with increasing orbital width (p < 0.001). It was ascertained that growth of the human eye during fetal life is correlated with growth of the orbit.

摘要

目的

本文旨在描述胎儿期人类眼球和眼眶的发育情况。

材料与方法

对18例孕龄在17至28周的人类胎儿（36只眼和36个眼眶）进行检查。胎儿因发育不成熟在出生后数小时内死亡，未发现任何发育异常。测量眼球的轴径和赤道径以及眼眶的深度和宽度。采用学生t检验和皮尔逊相关系数对数据进行统计学分析。

结果

发现眼球的轴长（p < 0.005）和赤道径（p < 0.001）以及眼眶的深度（p < 0.001）和宽度（p < 0.001）随年龄增长而增加。此外，眼球轴长的增长与眼眶深度的增加平行（p < 0.001），而赤道径的增长与眼眶宽度的增加一致（p < 0.001）。确定胎儿期人类眼睛的生长与眼眶的生长相关。
