Purpose To evaluate the efficacy of Pascal Laser Trabeculoplasty (PLT) employing reduced energy levels in patients with OHT or POAG. Methods Prospective, pilot study including 12 patients with OHT or POAG. Pascal laser trabeculoplasty was performed on the inferior 180° of the treated eye after titrating the energy for each patient. The IOP was measured with Goldmann applanation tonometer (GAT) on laser treatment day (D0), 1 week post laser (D7) and 1 month post laser (D30). Anova for repeated measurements was used for the statistical analysis. Results The mean IOP on D0 was 25.2 ± 1.4 mmHg (range: 22 to 28.4 mmHg), mean IOP on D7 was 23.1 ± 1.5 mmHg (range: 19.8 to 26.4 mmHg) and mean IOP on D30 was 20.6 ± 1.1 mmHg (range: 18 to 23.1 mmHg). There was no significant difference between the D0 IOP and D7 IOP (p= 0.43) but between D0 IOP and D30 IOP (p= 0.001) Conclusion Patterned laser trabeculoplasty causes significant IOP decrease after 1 month. In this pilot study The IOP drops by 20% after 1 month.
