Ngamchittiampai C Objective: To evaluate the efficacy and safety of selective laser trabeculoplasty (SLT) as a treatment of primary
open angle glaucoma (POAG).
Material and Method: In a prospective clinical study, 21 eyes suffering from POAG were treated with SLT over
inferior 180 degrees of trabecular meshwork. The intraocular pressure (IOP) was measured before and 1 hour,
1 week, and 1, 3, 6,and 12 months after the treatment. The glaucoma medications were continued on the same
regimen during the study period.
Results: The mean preoperative IOP was 18.6 mmHg (SD 2.2). The mean IOP reduction were 4.9 mmHg
(26.3%) 1 hour after SLT, 2.6 mmHg (14.0%) 1 week after SLT, 4.0 mmHg (21.5%) 1 month after SLT, 3.5 mmHg
(18.8%) 3 months after SLT, 3.7 mmHg (19.9%) 6 months after SLT, and 3.3 mmHg (17.7%) 12 months after
SLT. There were minimal adverse reactions including conjunctival injection and mild anterior chamber reaction.
Conclusion: SLT is a safe and effective procedure to reduce IOP in POAG patients.
