About this trial

This is an interventional treatment trial for Open Angle Glaucoma focused on measuring open angle glaucoma ocular hypertension

Eligibility Criteria

40 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • 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.

Exclusion Criteria:

  • 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 disease.
  • Having participated in any other clinical study within the last month.
