Abstract Details

Purpose:

To evaluate the efficacy of direct application of SLT irradiation to the perilimbal area.

Setting:

A prospective, randomized, masked, controlled clinical trial.

Methods:

Patients with uncontrolled open angle and pseudoexfoliation glaucoma who were candidates for laser trabeculoplasty were enrolled to the study. The controls underwent conventional SLT with 100 spots delivered using a gonioscopy lens for 360° of the trabecular meshwork. The study group underwent trans-scleral irradiation using the same parameters. Applications were administered at the peri-limbal area.

Results:

Mean (± SD) pre-treatment IOP: 20.21±3.19 mmHg for the study group (n=14) and 21.14± 2.98 mmHg for the controls (n=14), (P= .434), dropping to 15.50±3.77 (n=14) and 15.00±4.08 (n = 14), (P = .744) and 16.00±1.88 (n = 7) and 14.3± 2.77 (n = 11), (P =0.375) after 6 and 12 months, respetively [Mann Whitney]. Success (≥15% reduction at 6 months with no additional medications/interventions) was achieved in 12 (85.7%) study patients and 9 (69.2%) controls (P = .385). Complications were mild and transient although significantly higher in the controls (P.0001).

Conclusions:

The results suggest that SLT applied directly to the peri-limbal sclera is as efficacious as the conventional procedure.
