Inclusion criteria

Inclusion criteria: Patients of either sex and any race, 18 years of age or older, diagnosed with open-angle glaucoma (with or without pseudoexfoliation or pigment dispersion component) or ocular hypertension. Patients inadequately controlled on a current stable (i.e., at least 4 weeks) IOP lowering medication. Inadequately controlled is defined as having a mean IOP = 18 mmHg in at least one eye at the Screening Visit. Patients must meet the following IOP entry criteria in at least one eye: For each qualifying eye, the mean IOP must be: = 24 mmHg and = 36 mmHg at the 9:00 time point at both Eligibility Visits 1 and 2, and = 21 mmHg and = 36 mmHg at the 11:00 and 16:00 time points at both Eligibility Visits 1 and 2.The same eye(s) must qualify at all qualifying time points at both Eligibility Visits 1 and 2. The mean IOP is the average of IOP measurements in the same eye. Patients must be able to discontinue use of all IOP-lowering medication(s) for a minimum period of 5 days to 28 days prior to Eligibility Visit 1. Patients must be on a stable dosing regimen of medications affecting IOP for at least 30 days prior to the Screening Visit and must not change the dosing regimen during the eligibility period Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range
