ABSTRACT
PURPOSE:
To determine the effect of intraocular pressure (IOP) reduction of selective laser trabeculoplasty (SLT) on medically uncontrolled open-angle glaucoma (OAG) and the factors associated with the treatment result.METHODS:
Forty-seven eyes of 47 OAG patients were enrolled for 180° SLT or 360° SLT, all under maximal tolerated medical therapy and with IOP above their target pressure. All patients were followed-up for at least 1 year after the procedure. Treatment success was defined as IOP reduction ≥20% from baseline at 12 months after SLT treatment without additional anti-glaucomatous intervention.RESULTS:
The treatment success rate was 65.96%. Baseline IOP was 23.84 ± 4.52 mmHg in the success group and 21.44 ± 2.97 mmHg in the failure group (p = 0.035). Significant mean IOP reduction was observed at 6, 9, and 12 month follow-ups (p = 0.001 at 6 months; 0.041 at 9 months, and <0.001 at 12 months). The success rate did not vary significantly by sex (p = 0.362), age (p = 0.081), history of cataract surgery (p = 0.470), number of medications (p = 0.857), duration of medication (p = 0.613), or angular degree of SLT treatment (180° vs. 360°) (p = 0.137). There was a positive correlation between mean baseline IOP and mean reduction of IOP from baseline in the success group (p < 0.001, r = 0.861), while there was no such correlation in the failure group (p = 0.272, r = −2.921).CONCLUSIONS:
SLT was an effective treatment for IOP reduction until 12 months in medically uncontrolled OAG patients. A greater amount of IOP reduction is expected in patients with higher baseline IOP in the success group.
