Original Article


To prospectively examine the effects of selective laser trabeculoplasty (SLT) on the anterior chamber angle (ACA) and its related parameters using anterior segment-optic coherence tomography (AS-OCT). Fifty eyes of 50 patients with primary open angle glaucoma (POAG) and ocular hypertension were included in the study. AS-OCT was performed before SLT application, immediately after and at 1 day and 1 month. Intraocular pressure (IOP), central corneal thickness (CCT) and anterior chamber depth (ACD) were also recorded and evaluated. No statistically significant difference was determined in ACA and other AS-OCT parameters (AOD, angle opening distance at 500 and 750 mm; TISA, trabecular-iris space area at 500 and 750 mm) before and 1 day after SLT application (p > 0.05). However, a statistically significant increase was determined in both the temporal and nasal ACA, AOD and TISA values between the baseline and day 30 (p < 0.001). No statistically significant change was observed in the CCT or ACD values (p > 0.05). SLT resulted in an increase in ACA, AOD and TISA when evaluated using AS-OCT. We think that this study provides a different perspective concerning the effects of SLT in the angle region and the involved mechanism.
