Change in IOP from baseline to week 12 was assessed in patients who transitioned from fixed-combination bimatoprost/timolol (n=57, primary endpoint). Secondary assessments included change in IOP at week 4, percentage of patients with IOP ≤18 mmHg at weeks 4 and 12, change in Ocular Surface Disease Index and ocular hyperemia scores at week 12, and patient preference. Adverse events were also reported.Results: IOP change (mean ± SD) from baseline to week 12 was –3.8±1.9 mmHg (P<0.001); results were similar at week 4. Most patients had IOP ≤18 mmHg at weeks 4 and 12 (78.6% and 85.5%, respectively). Mean Ocular Surface Disease Index score was significantly reduced (P<0.001); no significant change in ocular hyperemia score was observed (P=0.197). Treatment-related adverse events included dysgeusia, nausea, paresthesia, myalgia, headache, and eye irritation (n=1 each). Most patients (74.5%) preferred travoprost/timolol over bimatoprost/timolol.Conclusion: Transition to travoprost/timolol significantly reduced IOP and was well tolerated in patients who had elevated IOP despite bimatoprost/timolol therapy. Polyquaternium-1–preserved travoprost/timolol was preferred over prior treatment with benzalkonium chloride–preserved bimatoprost/timolol.
