Abstract: The present invention relates to a system for the stereoscopic examination of a patient's eye using a slit-lamp microscope (3), wherein the patient's eye (1) is illuminated by a light strip of a predetermined cross section which is emitted by a light source (5). The light source (5) is arranged on the vertical arm (20) of a support (7) and the eye (1) to be examined is placed in an essentially horizontal plane on one side of said support. The stereo-microscope (3) is essentially placed on a plane which is located on the side opposite to the first side of the support (7). The vertical arm (20) of the support (7) is made in the shape of a column having a narrow cross section so as to minimize the optical obstruction between the stereo-microscope (3) and the patient's eye. Using at least one beam (30b) from the stereo-microscope (3), a partial ray is stopped down and the image information of said ray is directed to a reception unit (44) located in said stereo-microscope (3).
