AIM: The aim of this study is to compare the efficacy of selective laser trabeculoplasty as initial or adjunctive treatment for primary open-angle glaucoma in a retrospective chart review. METHODS: 28 eyes of 28 patients with newly diagnosed primary open-angle glaucoma, who formed the initial selective laser trabeculoplasty group, and 31 eyes of 31 patients suffering from medical uncontrolled primary open-angle glaucoma, who formed the adjunctive selective laser trabeculoplasty group, were treated with 180° selective laser trabeculoplasty. Patients were evaluated 1, 3, 6, 12, 18 and 24 months after treatment. Success was defined as an intraocular pressure lowering exceeding 20% of pretreatment intraocular pressure. RESULTS: The mean follow-up time was 20.25 months (standard deviation = 8.1) for the initial selective laser trabeculoplasty group and 18.87 months (standard deviation = 8.8) for the adjunctive selective laser trabeculoplasty group (p = 0.538). No significant difference was found between the two groups for mean pretreatment intraocular pressure (21.43 mmHg (standard deviation = 3.2) vs 21.97 mmHg (standard deviation = 2.6); p = 0.766), for mean intraocular pressures and mean intraocular pressure reductions during whole follow-up period. At all follow-up visits, the mean percent intraocular pressure reduction was smaller in the adjunctive selective laser trabeculoplasty group than in the initial selective laser trabeculoplasty group, and such a difference was significant at 1 month (21.55% vs 26.79%; p = 0.039) and 24 months (24.82% vs 28.10%; p = 0.041). According to the Kaplan-Meier survival analysis, the 24-month success rate was 71.4% in the initial selective laser trabeculoplasty group and 71% in the adjunctive selective laser trabeculoplasty group, with no differences between the groups (p = 0.913). CONCLUSION: Selective laser trabeculoplasty is equally efficient in reducing intraocular pressure as initial or adjunctive treatment for primary open-angle glaucoma over 24 months.
