Following a short summary of the anatomical and physiological aspects of the surgical procedure, the authors present a series of 320 eyes operated upon by the method of angiodiathermocoagulation. Open-angle glaucoma, followed by aphakic glaucoma, respond the best to this procedure, the expected number of good results being approximately 25% where the criteria are severe. The low percentage of severe complications represents one of the greatest advantages of angiodiathermocoagulation, which may be recommended in desperate cases.
