Abstract | AIMS: The aim of this study was to determine the effectiveness of timolol gel-forming solution as a monotherapy and to compare the efficacy of timolol gel-forming solution morning instillation versus at night application in Asians with newly diagnosed open-angle glaucoma. METHODS: A retrospective, comparative, parallel group study was conducted on 78 eligible patients diagnosed with open-angle glaucoma who received topical timolol gel-forming solution either on morning (AM dosing group; 39 patients) or evening (PM dosing group; 39 patients) as monotherapy treatment. Intraocular pressure was taken at baseline, 1, 3, 6, and 12 months post-treatment. RESULTS: Mean baseline intraocular pressure (IOP) for timolol gel-forming solution in general was 22.7 +/- 6.6 mmHg with the mean IOP reduction of 5.7 +/- 5.3 mmHg (23.1% reduction). The mean IOP reduction of the AM dosing group was 7.5 +/- 5.2 mmHg (31.0% reduction) and 3.9 +/- 4.9 mmHg (15.1% reduction) in the PM dosing group (P = 0.0002). There was a statistically significant difference of IOP reductions between AM and PM dosing group at 1 month (P = 0.041), 3 months (P = 0.037) and 12 months (P = 0.015) post-treatment. Seventy-five percent (24) of good responders was in the AM group and 67.4% (31) of poor responders were patients in the PM group. CONCLUSION:
Timolol gel-forming solution is effective in reducing IOP in Asian eyes. Morning dosing was more effective in lowering the IOP compared to evening dosing.
