Abstract
Purpose :
In an East Asian population, there have been a few studies reporting the clinical results of selective laser trabeculoplasty (SLT) on uncontrolled pseudoexfoliation glaucoma (PXFG). We performed a retrospective, observational study to investigate the efficacy and safety of SLT in Korean eyes with PXFG refractory to maximum tolerated medical therapy.
Methods :
Twenty-four eyes of 24 patients with medically uncontrolled PXFG were treated with SLT. Intraocular pressure (IOP) was measured before SLT and 1 day, 1 week, 1, 3, 6 months and 1 year after SLT. Treatment success was defined as IOP reduction ≥ 20% without additional laser or glaucoma surgery.
Results :
The mean IOP was 27.7 ± 6.5 mmHg and the mean number of anti-glaucoma drug was 3.7 ± 1.0 preoperatively. There was significant IOP decrease at postoperative 1 day (20.9 ± 9.5 mmHg), 1 week (16.0 ± 4.5 mmHg), 1 month (17.7 ± 5.9 mmHg), 3 months (16.0 ± 3.9 mmHg), 6 months (16.8 ± 4.0 mmHg), 1 year (19.5 ± 8.2 mmHg) (all P < 0.05). No significant change was observed in the mean number of anti-glaucoma drug (P > 0.05). The cumulative probability of treatment success at 6 months after SLT was 58% and at 1year after SLT was 50%. More than half (53.8%) of failure was observed within 3 months after SLT. Overall follow up period, there was no significant adverse events except 3 eyes (12.5%) of IOP spike (IOP rise of ≥ 5 mmHg than pretreatment IOP within 1 hour).
Conclusions :
SLT seems to be a safe and effective procedure to lower IOP in Korean patients with medically refractory PXFG.
