The Outcome of 270-Degree Selective Laser Trabeculoplasty
Purpose. To evaluate the reduction of intraocular pressure (IOP) by a single-session 270° selective laser trabeculoplasty (SLT) in pseudoexfoliation glaucoma (PXFG) and primary open angle glaucoma (POAG) patients. Methods. A successful outcome was defined as an IOP reduction ≥20% from baseline with...

| Summary: | Purpose. To evaluate the reduction of intraocular pressure (IOP) by a single-session 270° selective laser trabeculoplasty (SLT) in pseudoexfoliation glaucoma (PXFG) and primary open angle glaucoma (POAG) patients. Methods. A successful outcome was defined as an IOP reduction ≥20% from baseline with no further need for laser or incisional surgery. The preoperative pharmaceuticals were maintained unchanged throughout the course of the study. 70–80 nonoverlapping pulses were distributed around 270° in the trabecular band. Results. Sixty-six eyes of 42 patients with PXFG (30 eyes) or POAG (36 eyes) met the inclusion criteria. The mean ± standard deviation preoperative IOP was 23.7±4.5 mmHg and at the end of the followup was 19.0±4.5 mmHg with a pressure drop of 4.7±3.1 mmHg (20%) (P<0.001, 95% confidence interval 3.94–5.46). The cumulative probability of success was 39% (26 of 66 eyes) after 6 months of followup. Statistically significant differences in success rates were observed between the PXFG and POAG groups (27% versus 50%; P=0.025). Postoperative inflammatory reaction was scanty. Conclusions. 270-degree SLT is useful in lowering IOP in PXFG and POAG, but the average reduction of IOP seems to be within the same range as reported with 180-degree SLT previously. |
