Inclusion criteria

* Unilateral or bilateral primary open angle glaucoma, capsular glaucoma, pigmentary glaucoma or ocular hypertension. * Patients currently on IOP reducing therapy: IOP greater than or equal to 25mmHg (Ltwo IOP determinations at pre-study separated by at least one hour) OR Patients without IOP reducing therapy: IOP greater than or equal to 30mmHg (two IOP determinations at pre-study separated by at least one hour).

Exclusion criteria

* History of acute angle closure or closed/barely open anterior chamber angle. * Current use of contact lenses. * Ocular surgery or argon laser trabeculoplasty (ALT) within three months prior to pre-study visit. * Ocular inflammation/infection occurring within three months prior to pre-study visit. * Hypersensitivity to benzalkonium chloride or to any other component of the study drug solutions. * Other abnormal ocular condition or symptom preventing the patient from entering the study, according to the investigator's judgement. * Patients with conditions in which treatment with B-blocking agents are contraindicated: cardiac failure, sinus bradycardia, second and third degree atrio-ventricular block. * Patients with conditions in which treatment with B-blocking agents are contraindicated: bronchial asthma, history of bronchial asthma or chronic obstructive pulmonary disease. * Inability to adhere to treatment/visit plan. * Have participated in any other clinical study within one month prior to pre-study visit.

Design outcomes

Primary

MeasureTime frame
The differences from baseline in diurnal IOP reduction after six months of treatment will be tested between the fixed combination and the monotherapy groups.6 months
Primary objective: to demonstrate that the fixed combination of latanoprost and timolol has a better IOP-reducing effect than the individual monotherapies.6 months

Secondary

MeasureTime frame
To compared the number of treatment failures and patients withdrawn due to uncontrolled IOP from baseline to Week 26 between treatment groups6 months
To describe the IOP development from baseline to Week 26 for all treatment groups6 months
To examine, within treatment groups, the diurnal IOP reducing effect from baseline for all effect from baseline between the monotherapies latanoprost and timolol6 months
To examine, within the fixed combination treatment group, the diurnal IOP reducing effect from baseline to Week 26 and Week 526 months
To follow the safety variables throughout the study periods.6 months
To compared the IOP reducing effect from baseline to Week 26 of the monotherapies with the IOP reducing effect from Week 26 to Week 52 of the fixed combination6 months
To compare the diurnal IOP reducing effect from baseline between the monotherapies latanoprost and timolol at Week 266 months
