Design outcomes

Primary

MeasureTime frame
Main Objective: Primary objective: To evaluate the subjective tolerance upon instillation (rate of patients experiencing symptoms of discomfort ) of carteolol LA compared to timolol LA in patients with simple ocular hypertension or POAG (superiority design);Secondary Objective: • Assessment of each of the symptoms of the Glaucoma Symptom Scale [15] (Yes/ No): burning/smarting/stinging, tearing, dryness, itching, soreness/tiredness, feeling of something in the eye, blurry/dim vision, hard to see in daylight, hard to see in dark places and halos around the light (for those who report a given symptom, a bothersome scale will be used: very, somewhat, a little, not at all) • Subjective tolerance upon isntillation graded as very good/good/bad/very bad • External and Slit lamp examination • Break up time • Fluorescein test • Lissamine green test. • IOP measured at 12 PM (+/- 30mn) • Visual acuity • Visual field • Fundoscopy • Adverse events • Compliance ;Primary end point(s): Safety : Primary variable : • Rate of patients experiencing discomfort upon instillation after 3 months of treatment
