Argon laser photocoagulation of the trabecular meshwork in open-angle glaucoma.

Argon laser photocoagulation is an effective surgical modality in the management of open-angle glaucoma. Twenty-two eyes with open-angle glaucoma were treated. Approximately 50 burns of 50 micron spot size were applied to the anterior trabeculum over the inferior 180 degrees of the angle. An average pressure drop of 6.1 mmHg was achieved. Complications were minimal, a transient postoperative pressure rise being the most potentially hazardous.
