用非接触型镜面反射显微镜对321只正常眼进行活体角膜内皮照相,研究细胞密度、细胞形态和年龄的关系。结果表明:(1)细胞密度越高、细胞形态越接近同形细胞;细胞密度越低,细胞形态越接近多形细胞。(2)细胞的多形性随年龄的增加而增加。(3)多形细胞和同形细胞二者的细胞密度均随年龄的增加而下降,但同形细胞下降的幅度较多形细胞明显。 321 corneal endothelial cells were photographed by non-contact specular microscope to study the relationship between cell density, cell morphology and age. The results showed that: (1) The higher the cell density, the closer the cell morphology was to the isomorphous cell; the lower the cell density, the closer the cell morphology to the pleomorphic cell. (2) cell polymorphism increases with age. (3) Cell density of both pleomorphic cells and isomorphic cells decreased with the increase of age, but the decrease of isomorphic cells was more than that of metaplex cells.
