Yj. Kim et Cs. Moon, One-year follow-up of laser trabeculoplasty using Q-switched frequency-doubled Nd : YAG laser of 523 nm wavelength, OPHTHAL SUR, 31(5), 2000, pp. 394-399
BACKGROUND AND 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.
MATERIALS AND METHODS: The 16 eyes of chronic open angle glaucoma patients
were treated in the method similar to argon laser trabeculoplasty using Q-s
witched, frequency-doubled Nd:YAG laser (523 nm). The treatment results wer
e followed and analyzed for a one-year period.
RESULTS: Mean intraocular pressure reduction of 3.81 mm Hg (15%) at 3 month
s, 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 r
esponder group that consisted of eyes showing 3 mm Hg or greater reduction.
Adverse reactions were minimal and not significant.
CONCLUSION: This new laser trabeculoplasty has shown reasonable efficacy an
d safety on a limited number of eyes over a one year duration.
