正常人角膜内皮的初步观察

本文报道应用非接触式角膜内皮显微镜,观察107例不同年龄正常人角膜中央部内皮细胞的形态,密度和面积的结果。正常青年和儿童的角膜内皮细胞呈六角形,大小一致;而40岁以上者形态和大小不一致。内皮细胞的密度随年龄增长而减低,面积随年龄增长而增加。本文并讨论了影响角膜内皮细胞形态、密度和面积的生理与病理因素,以及角膜内皮细胞形态,密度和面积改变的临床意义。

PRELIMINARY OBSERVATION OF NORMAL HUMAN CORNEAL ENDOTHELIUM

This paper reports the shape, density and size of endothelial cells of central cornea which were observed under noncontact specular microscope in 107 normal persons with a wide range age.The normal corneal endothelial cells of youths and children were hexagonal in shape and uniform in size, but they became irregular both in shape and size in persons above 40 years old.The density of the corneal endothelial cells was decreased with an increase of age while the size was increased with an increase of age. The physiological and pathological factors which affect the shape, density and size of the corneal endothelial cells and the clinical significance of these changes of the corneal endothelial cells are also discussed
