title: [Technique employing argon laser coagulation to obtain trabecular retraction].
abstract: A technique for treating primary open angle glaucoma by argon laser photocoagulation is described. Its elective action on the trabeculum and on trabecular "collapse" in the absence of any trabecular perforation suggested the name of "trabecular retraction" for this procedure. Its efficacy depends on very good visibility of the trabeculum through 360 degrees, on perfect focalization of the point of impact to 50 mu, and on the application of one hundred or so impacts distributed throughout 360 degrees. Any pretrabecular obstacle must be eliminated. Mean pressure drap obtained is 10 mmHg. Complications are minimal and results comparable or superior to those of surgery.
