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