Materials and methods: Twelve eyes of 12 patients with high intraocular pressures (IOP?21 mmHg), despite maximally tolerated antiglaucomatous treatment, were included in this study. Repeat SLT was carried out if the fi rst SLT failed (IOP ?21 mmHg). Patients had follow-ups at the 1 week and 1, 3, 6 and 9-month after treatments.
Results: The mean IOP before the fi rst SLT was 25.00±1.54 mmHg which decreased to 20.25±1.76 mmHg 9 months later for all patients (p=0.001). Moreover after a mean of 13.0±3.26 months following the fi rst SLT, 6 patients (50 %) received repeat SLT. In these patients, the mean IOP decreased from 23.50±1.76 mmHg to 19.83±1.83 mmHg after 6 months (p=0.004). At the end of a mean 19.0±3.68-month of study period, the IOP decreased to 20.58±1.62 mmHg in all patients (p=0.001). The overall success rate was 58.3% at the end of the study, and there were no signifi cant differences between the fi rst and repeat SLT success rates at similar control time points (p>0.05).
Conclusion: There was no signifi cant difference between the fi rst and repeat SLT effectiveness in SO-induced OAG patients. However, further studies are needed to validate the effects of a repeat SLT on SO-induced OAG.
