Objective: To compare the effectiveness of argon laser trabeculoplasty (ALT) and selective laser trabeculoplasty (SLT) in lowering intraocular pressure (IOP) in younger patients (age 60 or less). %26lt;br%26gt;Methods: This was a prospective randomized control trial. Forty-two young patients (age 29 to 60 y) had 1 eye randomized to ALT (n = 22) or SLT (n = 20). IOP was measured before laser and 1 hour, 1 day, 6 weeks, 3 months, every 3 months until 2 years, and then yearly postlaser. Chi-square analysis and Student t test were used to determine statistical significance. %26lt;br%26gt;Results: The mean IOP before treatment was 21.9 mm Hg for ALT and 19.1 mm Hg for SLT with no statistical difference between the groups (P %26gt; 0.05). At 2 years, 86.4% of ALT and 75.0% of SLT eyes required no further surgical intervention (laser trabeculoplasty or trabeculectomy). During the same time period, there was a statistically significant IOP decrease of 11.1% after ALT (P = 0.01) and 7.7% after SLT (P = 0.01) with no statistical difference between the lasers (P %26gt; 0.05). %26lt;br%26gt;Conclusions: In younger patients, both ALT and SLT have a significant ocular hypotensive effect 2 years after treatment, with no differences in outcome identified between the laser modalities.
