Abstract: Controlled, prospective, longitudinal, clinical trial with the objective to compare the efficacy of the micropulse laser trabeculoplasty (MLT) and the selective laser trabeculoplasty (SLT) in patients with open angle glaucoma or ocular hypertension. Patients were divided into two groups depending on the laser procedure, the group 1 was treated with SLT and the group 2 was treated with MLT; then they were followed for 3 months. 67 eyes were included in the trial (SLT: 38 eyes of 24 patients and MLT: 29 eyes of 19 patients). The average of age of the patients treated with SLT was 68.4 ± 8.8 years and with MLT 77.7 ± 7.3 years. The previous IOP was similar in both groups (SLT: 19.53 ± 4.03 mmHg, MLT: 19.76 ± 4.23 mmHg), a week after treatment (SLT: 18.53 ± 4.08 mmHg, MLT: 17.14 ± 5.19 mmHg), at month (SLT: 14.79 ± 2.42 mmHg, MLT: 16.26 ± 3.39 mmHg) and at 3 months (SLT: 15.66 ± 2.48 mmHg, MLT: 15.83 ± 3.19 mmHg). The percentage of IOP reduction was 19.81% with SLT and 19.89% with MLT. There was no statistically significant difference between the average IOP of both groups over 3 months of follow up. There was no difference in the number of drugs previous and posterior to the procedures, and there was not observed complications at any of the groups. The IOP-lowering effect of SLT and MLT was similar over 3 months in this group of patients and both proved to be safe procedures.
