Abstract |
To analyze the results of repeat selective laser trabeculoplasty (SLT). participants with primary or secondary open-angle glaucoma (excluding uveitic) who had undergone SLT 360° (SLT 1) with diminution of response over time followed by repeat SLT 360° (SLT 2). Six months of follow-up were required and at least 6 months in between SLT 1 and 2. The main outcome measures were IOP reduction at 6 and 12 months and a comparison of the response between SLT 1 and 2. One hundred thirty-seven patients met the inclusion criteria. If only one eye had repeat treatment, that eye was chosen; if both eyes qualified, one was chosen at random. The baseline intraocular pressure (IOP) for SLT 1 = 20.3+/- 5.2 mmHg and SLT 2 = 19.4 +/- 5.0 was reduced to 16.4 +/- 3.9 and 16.7 +/- 4.7 at 1 year, respectively (p < .001). Medication use was not significantly changed, and was 2.2 +/- 1.2 at baseline for SLT 1 and 2.1 +/- 1.3 for SLT 2, and at 1 year was 1.9 +/- 1.3 and 2.2 +/- 1.2, respectively. A subanalysis of 62 patients matched for equivalent baselines showed a baseline IOP = 18.7 +/- 3.8 for SLT 1 and 18.7 +/- 3.5 for SLT 2, reduced to 16.0 +/- 4.3 and 15.3 +/- 3.8 at 1 year (p < .001). Repeat SLT laser (360-degree treatment, followed by a loss of effect over time, then a second 360-degree treatment) in this population resulted in IOP lowering similar to that of the initial treatment. |
