INTRODUCTION: Argon laser trabeculoplasty (ALT) and pattern laser trabeculoplasty (PLT) are two laser surgery methods for treatment of open angle glaucoma and the effect in reducing intraocular pressure (IOP) of these methods was compared in a retrospective study. METHODS: The IOP, the best corrected visual acuity (BCVA) and the eye drop glaucoma medication used by patients who were treated by ALT or PLT in this clinic between January 2011 and December 2012 were compiled and evaluated. RESULTS: An ALT was carried out on 22 eyes from 22 patients (13 right and 9 left eyes in patients with an average age of 71.1 ± 1.5 years, 7 men and 15 women) and a significant average reduction of IOP from 18.6 ± 0.9 to 15.3 ± 0.7 mmHg (p < 0.001) was observed an average of 8.2 ± 0.8 weeks after ALT. The number of dropped glaucoma medications per eye (p = 0.19) and the mean BCVA both remained constant (p = 0.15). A PLT was carried out on 20 eyes from 20 patients (12 right and 8 left eyes in patients with an average age of 69.9 ± 2.6 years, 10 men and 10 women) and a significant average reduction of IOP from 20.2 ± 1.1 to 15.6 ± 0.8 mmHg (p < 0.001) was observed an average of 8.3 ± 0.6 weeks after PLT. The number of dropped glaucoma medications per eye (p = 0.08) and the mean BCVA both remained constant (p = 0.59). The difference in the reduction of IOP between the ALT and PLT groups was not significant (p=0.26). CONCLUSION: Both PLT and ALT are effective methods for treatment of open angle glaucoma and lead to similar significant reductions in IOP.
