Text: In the argon laser group, the average intraocular pressure was 24. 4 + / - 3. 5 mm Hg before treatment and 17. 6 + / - 1. 7 mm Hg (or a 24. 7 % + / - 11. 4 % mean pressure reduction) at 1 month, 16. 8 + / - 2. 5 mm Hg (or a 26. 7 % + / - 15. 3 % mean reduction) at 2 months, and 15. 5 + / - 1. 2 mm Hg (or a 30. 0 % + / - 16. 5 % mean reduction) at 3 months after laser trabeculoplasty.
