Abstract
An arrangement for laser coagulation at the ocular fundus with at least one illumination light source for an illumination beam path, with a laser arrangement for generating a sighting and therapy beam path, wherein the sighting radiation and therapy radiation have different wavelengths, with observation optics for visual observation of the ocular fundus, for selecting the coagulation site and/or for monitoring the results of coagulation, and with a protective mechanism which prevents the laser radiation from penetrating into the eye of the person administering treatment. An optical element arranged in the sighting and therapy beam path is provided as a protective device, wherein this optical element has a plurality of optically active areas whose optical characteristics differ from one another. In this way, an uncomplicated construction of the device which is characterized by an extremely high degree of safety for the treating person is achieved.
