| Popis: | PURPOSE: To evaluate the intraocular pressure (IOP)-lowering effect of laser trabeculoplasty (LTP) in eyes which IOP had been substantially reduced by intensive topical treatment for one week.METHODS: Patients with newly diagnosed open-angle glaucoma were randomized to treatment with three IOP-lowering substances. One week later, 360° argon or selective LTP was performed. IOP was measured before LTP and at one-, three-, six- and 12-month post-LTP. The patients were part of the Glaucoma Intensive Treatment Study (GITS).RESULTS: Mean IOP (± SD) in 152 eyes of 122 patients was 14.0 (± 3.5) mmHg just before LTP. For every mmHg higher IOP prior to LTP, the IOP was reduced by an additional 0.6 mmHg at 12 months. The IOP was significantly reduced at all follow-up visits from -2.6 (± 3.1) mmHg at one month to -2.1 (± 3.8) mmHg at 12 months in eyes with pre-LTP IOP ≥ 15 mmHg, while no significant IOP reduction was seen in eyes with pre-LTP IOP < 15 mmHg. Older age, argon LTP and male sex were associated with larger IOP reduction after 12 months, whereas presence of exfoliation syndrome was associated with a smaller IOP reduction. No severe complications were reported.CONCLUSION: Success of LTP was highly dependent on the IOP level prior to LTP treatment. A sustained significant IOP reduction was seen in eyes with pre-LTP IOP ≥ 15 mmHg whereas no such effect was seen in eyes with pre-LTP IOP < 15 mmHg. Thus, LTP can be considered in eyes with multi-treatment when target pressure of < 15 mmHg is not achieved. (Less) |
