| Sumario: | Jacky WY Lee,1,2 Catherine WS Chan,2 Mandy OM Wong,3 Jonathan CH Chan,3 Qing Li,2 Jimmy SM Lai2 1The Department of Ophthalmology, Caritas Medical Centre, 2The Department of Ophthalmology, The University of Hong Kong, 3The Department of Ophthalmology, Queen Mary Hospital, Hong Kong Background: The objective of this study was to investigate the effects of adjuvant selective laser trabeculoplasty (SLT) versus medication alone on intraocular pressure (IOP) control, medication use, and quality of life in patients with primary open-angle glaucoma.Methods: This prospective, randomized control study recruited 41 consecutive primary open-angle glaucoma subjects with medically-controlled IOP ≤21 mmHg. The SLT group (n=22) received a single 360-degree SLT treatment. The medication-only group (n=19) continued with their usual treatment regimen. In both groups, medication was titrated to maintain a target IOP defined as a 25% reduction from baseline IOP without medication, or <18 mmHg, whichever was lower. Outcomes, which were measured at baseline and at 6 months, included the Glaucoma Quality of Life-15 (GQL-15) and Comparison of Ophthalmic Medications for Tolerability (COMTOL) survey scores, IOP, and the number of antiglaucoma medicines. Results: The baseline IOP was 15.8±2.7 mmHg and 14.5±2.5 mmHg in the SLT and medication-only groups, respectively (P=0.04). Both groups had a comparable number of baseline medication (P=0.2), GQL-15 (P=0.3) and COMTOL scores (P=0.7). At 6 months, the SLT group had a lower IOP (P=0.03) and required fewer medications compared with both baseline (P<0.0001) and with the medication-only group (P=0.02). There was no statistically significant difference in the 6-month GQL-15 or COMTOL score as compared to baseline (P≥0.4) or between the two treatment groups (P≥0.2).Conclusion: A single session of adjuvant SLT provided further reductions in IOP and medication without substantial changes in quality of life or medication tolerability at 6 months.
