Studying formation and development of fetal organ system, it has reliable information in medical theory as well as practical importance for the medical diagnosis, treatment and prevention in certain country. Introducing the modern advanced methods of fetal study in our country, it will be possible to get the necessary information of prenatal organ development, formation and differentiation. Currently, the research works of eyeball development, topography, structures have not been accomplished yet in the Mongolian human fetuses. Therefore, the aim of this work was to make an evaluation of the development of the human eye during the fetal life. In our study, the 66 eyeballs of 33 human fetuses were examined. It was observed that the axial length, corneal diameter and equatorial diameter of the eye were increased simultaneously in the early fetal period. In the late period the axial length was increased slightly and equatorial diameter was increased rapidly. In the histological observation, the thickness of the eyeball layers were increased regularly from the early fetal period until the late fetal period. Thickness of the choroid and retina were increasing irregularly. Anti VEGF antibody was high distinguished detected in the choroid and retina in the early fetal period but it was middle distinguished detected in the late fetal period by immunohistochemistry
