ABSTRACT

Purpose: To evaluate the effectiveness and incidence of complications of the sequential use argon-Neodymium-YAG laser vs. Nd:YAG laser.
Methods: We realized a prospective study in 20 eyes with occlusive angles.Intraocular pressure was measured and we evaluated angle by gonioscopy, the immediate and late complications were analyzed in both groups (10 vs. 10).
Results: Intraocular pressure diminished in both groups, endothelial cells lost was higher in the sequential Argon-Nd:YAG group in comparison with the Nd:YAG group; total energy used was smaller in the Argon-Nd:YAG group. As for the appearance of complications there was only a difference in the appearance of the hypemia in the Nd:YAG group.
Conclusions: The Nd:YAG laser is currently the instrument of choice in most patients with acute angle closure. Sequential argon-Nd:YAG iridotomy is a safe and effective procedure and combines the advantages of both laser procedures. It should be reserved for those cases that a permeable iridotomies can’t achieved with the Nd:YAG laser and in patients in those bleeding is a concern like those with uveitis or rubeosis.
