One year results of selective laser trabeculoplasty in the treatment of primary open angle glaucoma.

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.
