BACKGROUND AND OBJECTIVE: To investigate the clinical efficacy and safety of a new laser treatment for open-angle glaucoma that targets pigmented cells in the trabecular meshwork for disruption. MATERIALS AND METHODS: Sixteen eyes of chronic open-angle glaucoma patients were treated by a method similar to argon laser trabeculoplasty using a Q-switched, frequency-doubled Nd:YAG laser (523 nm). The treatment results were followed and analyzed over a one-year period. RESULTS: A mean intraocular pressure reduction of 3.81 mmHg (15%) at three months, 3.94 mmHg (16.1%) at six months, and 4.93 mmHg (20.2%) at 12 months from the baseline was obtained. Slightly greater reductions were seen in the responder group that consisted of eyes showing 3 mmHg or greater reduction. Adverse reactions were minimal and not significant. CONCLUSION: This new laser trabeculoplasty has shown reasonable efficacy and safety on a limited number of eyes over a one-year duration.
