2Uz. Dr., S.B Haydarpaşa Numune Eğitim ve Araştırma Hastanesi, Göz Kliniği, İstanbul - TÜRKİYE Aims: The purpose of this study was to evaluate changes in choroidal thickness (CT) in patients with pseudoexfoliative glaucoma (PXG) after argon laser trabeculoplasty (ALT).
Methods and Materials: This study included 55 eyes of 33 patients with PXG that required ALT. CT and intraocular pressure (IOP) were measured at three pm before and at one week, one month, three months after ALT. The CT was measured with optical coherence tomography (OCT) at the subfovea and 1500 ?m temporal and nasal at the foveal center. The relationships between changes in CT and changes in IOP were explored. Friedman?s ANOVA test, Wilcoxon test and Pearson?s correlation coeffi cient were used to statistical analyses. P<0.05 values were considered statistically signifi cant.
Results: Mean age was 69.4±7.9 years. While CT was signifi cantly increasing at subfoveal and temporal locations, it signifi cantly decreased at nasal location after ALT (P=.000). The mean IOP (± SD) decreased from 25.3 (± 3.1) mm Hg to 17.5 (± 2.3) mm Hg (with same antiglaucoma medications) at third month (P =.000). Changes in CT were not correlated with IOP changes.
Conclusions: While subfoveal and temporal localization of choroidal thickness were increasing, it decreased in nasal localization after ALT in PXG, but it was not related to decreasing IOP. We believe that further study is required.
