Abstract:
PURPOSE: To evaluate the pressure-lowering effects of single-spot laser trabeculoplasty and patterned laser trabeculoplasty using a 577-nm wavelength laser. METHODS: A total 35 eyes of 35 patients with primary open-angle glaucoma were enrolled in this study. Eighteen eyes of 18 patients were treated with 360degrees single-spot laser trabeculoplasty and 17 eyes of 17 patients were treated with 360degrees patterned laser trabeculoplasty. All patients were evaluated after laser trabeculoplasty at 1 week, 1 month, 3 months, and 6 months using slit lamp examination and Goldmann applanation tonometry. RESULTS: At 6 months postoperatively, the single-spot laser trabeculoplasty group had a mean IOP of 15.89 +/- 3.89 mm Hg with a mean IOP reduction of 37.1%, while the patterned laser trabeculoplasty group had a mean IOP of 17.57 +/- 2.64 mm Hg with a mean IOP reduction of 27.1%. CONCLUSIONS: Laser trabeculoplasty with a 577-nm optically pumped semiconductor laser was safe and demonstrated an IOP lowering effect. There were no significant differences in the IOP lowering effects between the single-spot laser trabeculoplasty and the patterned laser trabeculoplasty.
