Abstract

Objective: To evaluate some impacting factor for SLT effectiveness on POAG eyes which was already treated with IOP lowering medications. Patients and Methods: Descriptive study on 40 eyes of 28 POAG and steroid-induced patients on IOP lowering medications who have been treated with 360^o SLT. VA, VF, IOP, gonioscopy, optic disc, Laser settings, number of IOP lowering medications were evaluated before treatment and after treatment at 2 weeks, 1 month, 3 months. Results: There were some relating factors for SLT outcome such as gender, trabecular pigment, pre-laser IOP. At 2 weeks after laser, success rate in male group was higher that female group (p=0.013). At 3 months, higher pigmented group had higher success rate (p=0.017). Similarly, at 1 month, higher pre-SLT IOP group got higher success rate (p=0.013). There was no significant relation between age, duration of disease, number of IOP lowering medications, disease stage and treatment outcome. Conclusion: the significant impacting factors for SLT outcome on OAG eyes under medications were gender, pr-laser IOP and trabecular pigment.
