2MD, Assoc.Prof, Department of Ophthalmology,Yeditepe University, Istanbul, Turkey DOI : 10.37844/glauc.cat.2022.17.18 Purpose: To determine the efficacy and reliability of micropulse laser trabeculoplasty (MLT) procedure in primary open-angle (POAG) and pseudoexfoliative glaucoma (PXG).
Materials and Methods: The medical records of 125 eyes of 125 glaucoma patients having uncontrolled high intraocular pressure (IOP) despite using topical anti-glaucomatous eye drops were included the study. Of all patients, 64 patients had POAG and 61 patients had PXG. MLT was applied to all cases with the aim of reaching the target IOP. The IOP were measured at 1st hour, 1st day, 1st, 3rd, 6th, and 12th months following MLT with Goldmann applanation tonometry. Those of measurements were compared to the baseline IOP measurements.
Results: The mean baseline IOPs was 22.4±1 mm Hg in eyes with POAG and was 22.5±2 mm Hg in eyes with PXG. The mean IOPs were significantly decreased in all follow-up sessions compared to baseline pre-laser values in both the POAG and PXG groups (p<0.001 for all sessions in both POAG and PXG patients). The success rate of the MLT procedure at the end of 12th moths, in terms of decresing IOP within the normal limit, was 68.8% in POAG and was 85.2% in PXG. Only one patient had developed a mild anterior chamber reaction after the procedure.
Conclusion: The lowering effect of the single-session MLT procedure on IOP in both POAG and PXG was more pronounced at the 1st week, and this effect continued at the 1st, 3rd, 6th and 12th months in both disease groups.
