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.1) and these light-emitting diodes are arranged to be switchable one by one by a center lighting switch and a peripheral lighting-change switch. By this arrangement, an magnified image of the cornea cells of required positions can be easily obtained by leading the view of the subject.
