The effect of primary argon laser trabeculoplasty on intraocular pressure reduction and quality of life in patients with pseudoexfoliation glaucoma

Abstract

SUMMARY – The aim of the study was to assess the impact of primary argon laser trabeculoplasty (ALT) on intraocular pressure (IOP) lowering and quality of life improvement in patients with pseudoexfoliative glaucoma. Sixty patients with newly diagnosed pseudoexfoliative glaucoma who underwent primary ALT (group 2) or medication therapy (group 1) were followed-up. The effect of ALT on IOP reduction, dry eye development and number of antiglaucoma drugs used was examined. Patients were examined at the beginning of the study and then after 6, 12, and 18 months. A statistically significant difference between IOP values was observed throughout the 18-month follow-up, with the highest significance recorded 6 months after ALT (p=0.009). Twelve months after the start of the study, the TBUT value was 6.0±0.8 s in group 1 and 8.4±0.7 s in group 2. In group 2, the value of Schirmer test was constantly above 10 millimeters. The number of antiglaucoma medications used in group 1 was statistically significantly higher as compared to group 2 throughout the 18-month study period. ALT was found to be better choice for temporary regulation of IOP in patients with pseudoexfoliative glaucoma.
