PRIMARY outcome

Timeframe: Day 0, 3 months

Population: All enrolled. Two subjects were excluded from the efficacy analysis due to an adverse event (1) and use of medication not permitted (1).

Diurnal intraocular pressure is the mean of the three timepoints measured (8AM, 12PM \& 4PM). Intraocular pressure was measured by Goldmann applanation tonometry. A negative number indicated a reduction in mean intraocular pressure.
