Inclusion criteria
The factors, or reasons, that allow a person to participate in a clinical study.
Show details

- Unilateral or bilateral primary open angle glaucoma, capsular glaucoma, pigmentary
glaucoma or ocular hypertension.

- Open angle glaucoma appearing more than 6 months after cataract surgery is recognized
as primary open angle glaucoma. (individuals requiring treatment bilaterally must
fulfill eligibility criteria for both eyes.)

- IOP of 22mmHg or higher obtained during the pre-study period.

- Patients currently not treated or on single-drug treatment for the elevated IOP are
eligible after a medication free period (wash-out) of:

1. 3 weeks for B-adrenergic antagonists

2. 2 weeks for adrenergic agonists

3. 5 days for cholinergics and oral carbonic anhydrase inhibitors.

Exclusion criteria
The factors, or reasons, that prevent a person from participating in a clinical study.
Show details

- History of acute angle closure.

- Severe trauma at any time.

- Intraocular surgery or argon laser trabeculoplasty within 6 months.

- Current use of contact lenses.

- History of severe dry eye syndrome.

- Ocular inflammation/infection with three months of inclusion.

- Any condition preventing reliable applanation tonometry.

- Unacceptable finding at pre-study ocular examination as specified in the Case Report
Forms.

- In Investigator regards monotherapy insufficient with respect to optic nerve head
and/or visual field status.

- Treatment of elevated IOP with any topical B-adrenergic antagonist regularly for a
period longer than 3 months and/or treatment at any time during 6 months prior to
study start.

- Cardiac failure, sinus bradycardia, second and third degree of atrio-ventricular
block.

- Bronchial asthma, history of bronchial asthma or chronic obstructive pulmonary
