Narrative Responses:

Purpose
Patterned Laser Trabeculoplasty (PLT) is a newly developed treatment modality. There was no report comparing efficacy between PLT and selective laser trabeculoplasty (SLT). The purpose of this study is to compare the efficacy of PLT with yellow wavelength and selective laser trabeculoplasty (SLT).

Methods
This study was a retrospective chart review. Participants were twenty-five eyes of 21 patients with open-angle glaucoma (OAG), of which 12 eyes underwent PLT and 13 eyes underwent SLT and were followed up for a maximum of 6 months. All patients were treated for 360 degrees.

Results
In the PLT group, the mean intraocular pressure (IOP) at baseline and 6 months was 21.8 (SD 5.0), 14.3 (3.3) mmHg, respectively. In the SLT group, the mean IOP at baseline and 6 months was 23.1 (6.9) and 17.1(3.4) mmHg, respectively. There was no significant difference in average reduction in IOP from the baseline between PLT and SLT (33 % and 21%, respectively).

Conclusion
PLT was found to be as effective as SLT in lowering IOP over a 6-months period.
