Long term effects on the lowering of intraocular pressure: selective laser or argon laser trabeculoplasty?

Objective: Selective laser trabeculoplasty (SLT) and argon laser trabeculoplasty (ALT) are used to lower intraocular pressure (IOP) in patients with open-angle glaucoma (OAG). We report long-term follow-up data comparing SLT to ALT.

Design: Follow-up of prospective randomized clinical trial.
