One-year follow-up of laser trabeculoplasty using Q-switched frequency-doubled Nd:YAG laser of 523 nm wavelength.
OBJECTIVE
To investigate clinical efficacy and safety of a new laser treatment of open angle glaucoma that targets pigmented cells in the trabecular meshwork for disruption.


METHODS
The 16 eyes of chronic open angle glaucoma patients were treated in the method similar to argon laser trabeculoplasty using Q-switched, frequency-doubled Nd:YAG laser (523 nm). The treatment results were followed and analyzed for a one-year period.


RESULTS
Mean intraocular pressure reduction of 3.81 mm Hg (15%) at 3 months, 3.94 mm Hg (16.1%) at 6 months, and 4.93 mm Hg (20.2%) at 12 months from the baseline were obtained. Slightly greater reductions were seen in the responder group that consisted of eyes showing 3 mm Hg or greater reduction. Adverse reactions were minimal and not significant.


CONCLUSIONS
This new laser trabeculoplasty has shown reasonable efficacy and safety on a limited number of eyes over a one year duration.
