Abstract: An apparatus for observing and photographing cornea cells including an indicator projecting means, and eye-front observation optical system, an illuminating system for illuminating through a slit the eyeball surface obliquely, an enlarged imaging optical system for forming an enlarged image of the subject part by a TV camera based on the illuminating light, and a cornea self-focusing detector which is automatically moved in X and Y directions with respect to the optical axis of the eye-front observation optical system such that the light spot on the monitor screen by the reflected light from the subject part of the position detection indicator is brought to a specified position on the screen whereby an enlarged image of the cells is recorded and photographed and displayed simultaneously with the eye-front image in which the light spot of the photographing sight is positioned.
