Effect of selective laser trabeculoplasty on macular thickness

摘要

Background: To investigate the effects of selective laser trabeculoplasty (SLT) on macular thickness change. Methods: Forty eyes of 40 consecutive patients with uncontrolled primary open-angle glaucoma with medical treatment were included in this prospective study. SLT was performed to the inferior 180°, and macular thickness was measured. Data were collected before SLT, and 1?week and 1?month after SLT. Macular thickness evaluation was performed in five quadrants, the central 1?mm quadrant (fovea = F), the nasal 3?mm quadrant surrounding F (NQ), temporal quadrant, superior quadrant (SQ), and inferior quadrant (IQ). The preoperative and postoperative thicknesses were compared. Results: There was an increase in macular thickness in the NQ, IQ, and SQ on the first week after SLT compared to preoperative measurements. On the other hand, there was no significant increase in the F and temporal quadrant. On the first month after SLT, thickness in the NQ, IQ, and SQ was back to preoperative measurements, and there was no significant change between the preoperative measurements in any quadrant. Conclusion: There was no significant increase in macular thickness shortly after SLT in our study.
