Efficacy of argon laser trabeculoplasty: 3-year preliminary results of a prospective placebo-controlled study

Abstract

Background: It was the purpose of this study to evaluate the efficacy of argon laser trabeculoplasty (ALT) in controlling intraocular pressure (IOP) and avoiding surgical intervention. We also investigated whether topically applied diclofenac sodium eye drops had an influence on the success rate of ALT compared with placebo eye drops.
