ABSTRACT:
An apparatus for ascertaining the number of cells of an endothelium of a cornea of a subject's eye includes a display for displaying an image of cells of an endothelium of a photographed cornea, square meshes for partitioning the image of the cells displayed on the display by the unit area, and an enlarging device for enlarging and displaying an area partitioned by one of the square meshes on the display. The square meshes and the image are correlatively moved in a right or left direction on the display. An operator counts the number of the cells per unit area in an enlarged image, so that the operator ascertains the total number of the cells of the corneal endothelium.
