Selective laser trabeculoplasty (SLT) is an important treatment option in open angle glaucoma. It has been shown to be as effective as argon laser trabeculoplasty in primary open angle glaucoma while having an improved safety profile. Its use is also indicated for other subtypes of open angle glaucoma (OAG) such as pseudoexfoliation (PXE) and pigmentary glaucoma. In this review, we present the current literature on the role of SLT in treating OAG. The indications, duration of effect, repeatability, cost effectiveness and clinical effectiveness of SLT were reviewed. Available evidence comparing SLT with ALT and medical treatment are also presented. We also discuss the applicability of SLT for PXE, pigmentary glaucoma, normal tension glaucoma and advanced OAG. Lastly, the complications of SLT and areas of further research are discussed.
