Laser coagulation of the retina

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 retin...

Beschreibung
Zusammenfassung:	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.
