Brief Summary:
To determine the predictive factors of a positive response to latanoprost 0.005% / timolol 0.5% fixed combination (defined as a 10% IOP reduction from baseline), after 12 weeks of treatment (age, sex, ethnic origin, patient's medical history, family history of OAG or OHT, concomitant systemic treatment with beta-blockers, etiology, IOP at baseline, corneal thickness, compliance, and adverse events).

Primary Outcome Measures :
  1. A positive response defined as an additional IOP reduction over 10% after 12 weeks of treatment in the intent to treat (ITT) population. [ Time Frame: after 12 weeks of treatment ]

Secondary Outcome Measures :
  1. Absolute and relative IOP change after 4 and 12 weeks of treatment [ Time Frame: week 4 and 12 ]
  2. Percentage of patients achieving a target IOP value: under 18 mmHg and under 16 mmHg after 12 weeks of treatment, [ Time Frame: week 12 ]
