Abstract Details

Purpose:

To evaluate the effectiveness of selective laser trabeculoplasty (SLT) on medically uncontrolled open-angle glaucoma (OAG) and to analyze the factors associated with the result of treatment.

Setting:

A retrospective analysis of 57 eyes (47 patients) with OAG who had reported to National Health Insurance Service Ilsan Hospital, South Korea. Period of study: January, 2011 to June, 2013.

Methods:

Fifty-seven eyes of forty-seven patients with OAG, which did not reach the targeted intraocular pressure (IOP) with maximum anti-glaucomatous medical therapy, were treated with 180° or 360° SLT. All patients were followed-up for at least 1 year after the procedure. Success was defined as ≥20% reduction in IOP from baseline at 12 months after treatment with no additional anti-glaucomatous intervention.

Results:

The mean baseline IOP was 22.70 ± 3.91 mmHg. The significant mean IOP reduction was observed at 1 week, 1, 3, 6, and 12 months of follow-up. The success rate was 61.4% in all of the patients and did not vary significantly by taking 2, 3 or 4 medications with the rates of 57.1%, 63.0%, and 60.9% (p=0.959). The success rates based on the duration of medications and between phakic and pseudophakic groups did not vary significantly (p=0.820 and p=0.738). The success rate of 360° SLT group (50.0%) was not different from that of 180° SLT group (65.9%; p=0.269) There was a positive correlation between mean baseline IOP and mean reduction in IOP from baseline (p<0.001, r=0.592).

Conclusions:

SLT was an effective treatment for IOP reduction in medically uncontrolled OAG. Patients with higher baseline IOP had more efficient treatment outcome.
