Abstract: An apparatus for observing cornea for transplantation comprising, a transparent receptacle with a transparent window showing excellent flatness, which is able to receive a cornea container (a sample vial), and to pour liquid (water) into said transparent receptacle, a holder holding said transparent receptacle, a supporting table receiving said holder freely rotatebly, and an optical system such as a specular microscope. In place of a cornea container, a cornea exclusive container may be used. Said cornea exclusive container is installed directly in said holder. Optical positioning means such as a mirror(s) and a camera(s) is set up in order to position easily the observing portion by microscope through the transparent window of said transparent receptacle or of cornea exclusive container.

Abstract: A method for displaying a photographing point of a cornea which is used in an apparatus for obtaining video images of corneal cells.

Abstract: An apparatus for obtaining visual images of cornea cells, which allows magnified images of cornea cells to be easily obtained at required important sites of the cornea cells including a center site one by one by changing over the site, by leading the view axis of the subject and without requiring the decision of the operator in obtaining magnified images of cornea cells. Also, in order to allow a correct imaging site to be known, an imaging position mark is displayed at a correct position on the eyeball surface on the eye-front imaging screen of a TV camera. For illuminating through a slit an eyeball surface (2) and forming a magnified image of cornea cells of the subject part on an image-receiving surface (34) of a TV camera (35) via a magnification-imaging optical system based on the illumination light, a center view target and a plurality of view targets of required positions around the center view target are set by visible-light emitting diodes (27), (27.sub.

Abstract: In examining the progress of patients before and after a cataract operation, the morphology of cornea endothelium cells used in medical treatment, may be determined from a cornea endothelium cell image with less labor. Center points of two-dimensionally continuous cells of a cornea endothelium cell image are entered into a computer, and peripheral points obtained by determining peripheral points which are center points of the cells within a specified distance from one center point are sorted clockwise. If an angle formed by successive two peripheral points and the center point is less than a specified angle, the greater of the two peripheral points in distance from the center point is excluded from the peripheral points.

Abstract: An apparatus for obtaining images of cornea endothelium including an illumination system for illuminating through a slit an eyeball surface of a subject eye, a magnification-imaging optical system for forming a magnified image of a subject part based on the slit illumination light, focusing-detection use receiving optics for receiving the cornea endothelium reflected light and cornea epithelium reflected light of the slit via at least an objective lens when a cornea endothelium image is formed on an imaging surface of the magnification-imaging optical system in a focused state and a mechanism for moving the apparatus body in a direction of the subject so that the apparatus body is brought to a cornea endothelium focused position.
