Optical observation device for observing an eye
An optical observation device ( 100 ) for observing an eye ( 22 ) is described, having a microscope means ( 1 ), in particular a stereoscopic means, for observation of the anterior segment of eye ( 22 ), and having a means ( 2 ) for visualizing the retina of eye ( 22 ), particularly a stereoscopic means, with at least one camera ( 21 ), in particular, a digital camera. In order to provide an optical observation device ( 100 ), with which the anterior eye ( 22 ) and the retina can be observed alternately, in particular stereoscopically, in a constructively simple way, it is provided according to the invention that visualizing means ( 2 ) is designed as an attachment module in front of microscope means ( 1 ) and that visualizing means ( 2 ) is disposed on a positioning device ( 12 ) and can be positioned in front of eye ( 22 ), in particular, at a short distance in front of eye ( 22 ), via positioning device ( 12 ).
1. An optical observation device for observing an eye, having a microscope means for observation of the anterior segment of the eye, and having a means for visualizing the retina of the eye, with at least one camera by which images of the retina are recorded, is hereby characterized in that the microscope means comprises an objective, in that the visualizing means, as seen from the direction of the eye to be observed, is designed as an attachment module in front of the objective of the microscope means, in that the at least one camera of the visualizing means is disposed on a positioning device and can be selectively positioned in front of the objective of the microscope means by means of the positioning device, and in that the optical observation device has a display for displaying the images produced by the camera and/or that the microscope means has at least one eyepiece and that the optical observation device has a means for reflecting the images produced by the camera into the at least one eyepiece.
2. The optical observation device according to claim 1 , further characterized in that the microscope means has at least one observation beam path and that the visualizing means is disposed in the observation beam path so that it can be alternately swung in and out by means of the positioning device.
3. The optical observation device according to claim 1 or 2 , further characterized in that the visualizing means has at least one first optical element for generating an intermediate image of the retina.
4. The optical observation device according to claim 3 , further characterized in that the camera is disposed in the plane of the intermediate image, which is produced by the first optical element.
5. The optical observation device according to claim 1 , further characterized in that the visualizing means has a means for producing a stereo image.
6. The optical observation device according to claim 1 , further characterized in that the visualizing means has at least one other second optical element.
7. The optical observation device according to claim 1 , further characterized in that a protective covering is provided for the visualizing means.
8. The optical observation device according to claim 1 , further characterized in that the visualizing means has an illumination means for illuminating the eye.
9. The optical observation device according to claim 1 , further characterized in that it has a control device, particularly for controlling the visualizing means and/or the positioning device of the visualizing means and/or the microscope means.
10. The optical observation device according to claim 6 , wherein the at least one other second optical element comprises at least one of an objective element and an optical magnification means.
11. The optical observation device according to claim 4 , wherein the first optical element is provided in such a way that it produces an intermediate image of the retina between the first optical element and at least one other second optical element.
12. The optical observation device according to claim 3 , characterized in that the intermediate image of the retina is provided within the visualizing means.
