The objective of this study was to describe the intraocular pressure-lowering efficacy of AL-3789 over a 24-hour period in patients with open-angle glaucoma compared to an untreated control. Patients received one treatment of AL-3789. Twenty-eight days after treatment, IOP was measured every 4 hours, beginning at 8 AM for 24 hours.
