Anordnung zur Laserkoagulation von unterhalb der Fundusoberfläche liegenden Retinaschichten und Verfahren zur Ermittlung von Veränderungen in tiefen Gewebeschichten der Retina

摘要

In an apparatus for treating the layers of the retina below the fundus of the eye 2, the degree of coagulation caused at a striking point by treatment laser 1 is monitored by projecting a measuring beam at the vicinity of the striking point and detecting 7 light reflected or scattered from the retina or fluorescence caused by the measuring beam. A refraction device 5 allows the striking point of the treatment beam on the fundus to be changed. The measuring beam may be provided by a second radiation source (8,fig 2) or may be obtained by switching and/or filtering the treatment laser 1.
