摘　　要：测算了胎龄 4～ 8个月的 38只胎儿角膜的角膜横径、中央厚度、前、后曲率半径、前表面积及前屈折力。结果表明角膜横径、前、后曲率半径均随胎龄增长而增加 ,呈正相关 ,角膜前表面屈折力则随胎龄增加而趋于变小 ,其每月减少的幅度呈递减态势。将固定后角膜用显微镜测微尺测量顶点厚度 ,并将其与固定前作同体比较 ,发现胎儿角膜 6个月以后就比成人厚 ,随胎龄增长而增厚。并求得直线回归方程为 y∧ =0 .7733x +0 .0 189。对角膜厚的原因进行了讨论。本文结果进一步充实了国人胎儿角膜的基础数据库 ,并为角膜移植材料的选择提供了参考依据。We studied the horizontal diameter,the central thickness,pre-curvature and post-curvature,pre-surface area,pre-reflection of 38 fetal comea from 4 to 8 month-fetus.The result shows that the horizontal diameter and the curvature of the cornea increase be bound to follow the increase in fetal month.There is a positive correlation,but pre-curvature decrease.We compared paired sample the fixed and unfixed cornea and attained a linear regression equation:y∧=0.7733x+0.0189.We found that fetal corneal are thicker than adult.when exceeding six months.
