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。
This article reports the use of non-contact corneal endothelium microscopy to observe the 107 cases of normal human corneal endothelial cell morphology, density and area of the results. Normal young children and children corneal endothelial cells hexagonal, the same size; and over the age of 40 forms and sizes are inconsistent. The density of endothelial cells decreases with age, and the area increases with age. This article also discusses the physiological and pathological factors affecting the morphology, density and area of corneal endothelial cells, as well as the clinical significance of corneal endothelial cell morphology, density and area changes.
