Effectiveness of selective laser trabeculoplasty in advanced open‐angle glaucoma

Abstract

AbstractPurposeTo study the effectiveness and safety of selective laser trabeculoplasty (SLT) for the treatment of advanced open‐angle glaucoma.MethodsWe carried out a prospective longitudinal study, including patients with advanced open‐angle glaucoma. Selective laser trabeculoplasty has been indicated either after failure of medical treatment or in cases of poor adherence to medical treatment. Measurements were obtained at 1 week, 1 month, 3 months and 6 months. Success was defined as a reduction in intraocular pressure (IOP) of more than 20% from baseline or a reduction of at least one antiglaucoma eye drops with stable intraocular pressure. A p value less than 0.05 was considered as statistically significant.ResultsFifty‐nine eyes were included in the study. Three types of glaucoma were present in our study: primary open‐angle glaucoma was the most common type followed by exfoliative glaucoma and pigmentary glaucoma. The success rate was 76.5% for failure of medical treatment and 80% for poor adherence. The most frequent side effects were the inflammatory reaction (18.6%) and the early IOP spikes (25.4%). The predictors of its effectiveness were the initial intraocular pressure (p = 0.03) and the percentage reduction in intraocular pressure at 1 month (p = 0.002).ConclusionsSelective laser trabeculoplasty is an effective and easy‐to‐perform physical treatment of advanced open‐angle glaucoma with a satisfactory safety profile (1,2). It overcomes poor adhesion problems. Our results need to be extended to assess long‐term success.Bibliography1. Garg A, Gazzard G. Selective laser trabeculoplasty: past, present, and future.
