Abstract:AIM: To evaluate the short-term results of 360° selective laser trabeculoplasty (SLT) in the treatment of patients with previously failed deep sclerectomy (DS). METHODS: Patients with open angle glaucoma with prior failed DS and insufficient postoperative intraocular pressure (IOP) control were enrolled. Preoperative and postoperative IOP were measured using a Goldmann applanation tonometer. One hundred non-overlapping laser shots were applied over 360°. IOP was measured before SLT and 1h after SLT. Follow-up was scheduled at the first week and at the first, third, and sixth months thereafter. RESULTS: A total of 22 eyes (13 patients) were included in the study with a male:female ratio of 1:1 and a mean age of 51.73±13.51y (28-73y). The mean IOP prior to SLT was 18.41±5.24 mm Hg, which decreased to 15.91±3.56 (P=0.071), 15.05±4.53 (P=0.097), 13.91±2.67 (P<0.001) and 13.95±1.84 mm Hg; (P<0.001) at 1wk, 1, 3, and 6mo of follow-up, respectively. This change was statistically significant at the 3mo and 6mo follow-up. The number of anti-glaucoma medications dropped significantly throughout the follow-up period (P=0.014). CONCLUSION: 360° SLT can be an effective complementary treatment after failed DS to decrease IOP and anti-glaucoma medications, thus improving patient compliance and tolerance.
