Symposium on Light-Coagulation

The purpose of this symposium on light-coagulation is not to show the superi­ ority of the argon-laser-coagulation or, on the contrary, of the classical photo­ coagulation, but rather to see, if possible, which are the respective indications and contraindications for xenon-are-coagulation as well as for argon-laser­ coagulation. So, for instance, the argon-Iaser-coagulator is perhaps more appropriate to treat the lesions at and around the macula and the optic disc, but for the peripheral lesions
