Levobunolol vs timolol for open-angle glaucoma and ocular hypertension

Abstract

A group of 162 patients with chronic open-angle glaucoma or ocular hypertension were treated twice daily for up to 15 months with one of the following topical ophthalmic solutions: 0.5% levobunolol, 1% levobunolol, or 0.5% timolol. Overall mean reductions in intraocular pressure were 8 mm Hg for patients receiving 0.5% levobunolol or timolol and 8.2 mm Hg for patients receiving 1% levobunolol. There were no significant differences between levobunolol and timolol in mean reductions in intraocular pressure, percent of patients with adequately controlled intraocular pressure, or life-table estimates of the probability of successful treatment.
