Figure 6. Effect of multiple doses of Travatan® on monkey IOP. One drop (30 μl) of Travatan® or Eyestream® (placebo) was administered topically on assigned eyes at 0 h (10:00 AM), 24 h, and 48 h (indicated by the arrows). Assessment of IOP was conducted by a masked researcher who was unaware of the treatments at 0 h immediately before dosing, 24 h immediately before dosing, 48 h immediately before dosing, 72 h, and 96 h post-treatment. Error bars represent SEM of IOP values (n=8). An asterisk denotes p<0.05 and a double asterisk denotes p<0.01 between the two groups by paired Student’s t-test.
