[Stabilization of the laser on the target. Scanning photocoagulator: the SLC (scanning laser coagulator)]

When lasers are used to cause burns on the retina they necessitate systems of great precision especially in the posterior pole. Different possibilities are now offered. The best one is based on the intensification of the same laser beam used for the observation in the Scanning Laser Ophthalmoscope: S.L.O. when it is at a point selected from the angiogram, converting this machine into a Scanning Laser Coagulator: S.L.C.
