Response to SLT vs. ALT in Patients Under 60 Years of Age

Glaucoma Clinical Trial

Official title: A Prospective, Randomized, Clinically Based Study on the Response to Selective Laser Trabeculoplasty Versus Argon Laser Trabeculoplasty in Patients Who Are Under 60 Years of Age

Status Completed

Clinical Trial Summary

Laser trabeculoplasty is a routine treatment for glaucoma and can be performed with either argon (ALT) or selective Yag (SLT) lasers. The effectiveness of each has not been studied in patients under 60 years, which is younger than average for the procedure. The study hypothesis is that there will be no difference between the two laser types.

Clinical Trial Description

Forty-two young patients (age 29 to 60) had one eye randomized to ALT (n = 22) or SLT (n = 20). Intraocular pressure was measured prior to laser and 1 hour, 1 day, 6 weeks, 3 months, every 3 months until 2 years, and then yearly post-laser. χ2 analysis and student's t-test were used to determine statistical significance. ;
