Study Endpoints

Primary Endpoints

Mean diurnal IOP at Day 8 (Stage 1)
Day 8 (8:00, 10:00, 12:00, 16:00)

Intraocular pressure (IOP) will be measured with a Goldmann tonometer. Diurnal IOP will be calculated as the average of the four measurements.

Mean diurnal IOP at Day 29 (Stage 2)
Day 29 (8:00, 10:00, 16:00)

Intraocular pressure (IOP) will be measured with a Goldmann tonometer. Diurnal IOP will be calculated as the average of the three measurements.

Secondary Endpoints

Mean IOP at each post-treatment timepoint (Stage 1)
Day 1 (8:00, 10:00, 12:00), Day 8 (8:00, 10:00, 12:00, 16:00)
Mean change from the diurnally adjusted baseline IOP at each post-treatment timepoint (Stage 1)
Baseline (8:00, 10:00, 12:00, 16:00), Day 1 (8:00, 10:00, 12:00), Day 8 (8:00, 10:00, 12:00, 16:00)
Mean percent change from diurnally adjusted baseline IOP at each post-treatment timepoint (Stage 1)
Baseline (8:00, 10:00, 12:00, 16:00), Day 1 (8:00, 10:00, 12:00), Day 8 (8:00, 10:00, 12:00, 16:00)
