Abstract: Light from an exit pupil of an illumination unit is directed to a beam splitter which directs the light to an objective. The retina is illuminated, if a real image of the exit pupil of the illumination unit and a real image of an entrance pupil of a camera unit are formable. The objective forms a real intermediate image of the retina between the objective and the camera unit. The beam splitter directs the light from the retina to the camera unit, while causing the path of the illumination and the path of the imaging to deviate for non-overlapping images of the exit pupil and the entrance pupil in the crystalline lens. A relay lens system forms a real image of the intermediate image on a detecting component with the light reflected from the retina for transforming the image into an electric form to be shown on a screen.

Abstract: A hand-held examination device for imaging the eye (106) comprises a user interface (108), infrared source (150) and visible light source (152). The infrared source (150) illuminates the eye (106) with infrared radiation, the examination device forms an image of the eye (106) while illuminated by infrared radiation, and the display shows the eye (106) illuminated by infrared radiation. The user interface (108) receives from the user a signal for generating an image. The visible light source (152) is switched on in a predefined manner in response to the received user signal for generating the image. The examination device generates at least one image of the eye (106) by using visible light in response to the received user signal for generating the image.

Abstract: A system for data transfer comprises a server of a patient data system and an auxiliary server, which has installation data associated with at least one accepted device identifier available. The auxiliary server receives the identifier determining an examination device and transmits the installation data associated with the examination device identifier to the server of the patient data system. The server of the patient data system installs the identifier determining the examination device automatically on the basis of the installation data on the server of the patient data system for data transfer. Data is transferred between the examination device and the server of the patient data system after the identifier has been installed.
