[Primary glaucoma and the laser].

The use of the laser for treatment of different forms of primary glaucoma is proposed. In closed-angle glaucoma its use is limited to those cases where a large part of the angle is capable of ensuring drainage of aqueous humor. Pupilloplasty could be an alternative to iridotomy for relieving pupillary blockage. Peripheral circular gonioplasty can enlarge the angle. Finally, the laser can reduce ciliovitreolenticular blockage in malignant glaucoma. In patients with open-angle glaucoma, trabeculoplasty should be performed in the interval between medical and surgical treatments. Initial results appear promising but further study is necessary to evaluate the value of this type of therapy.
