Figure 5. Effect of a single dose of 30 μl Travatan® on monkey IOP. Travatan® or Eyestream® (vehicle) was administered topically on assigned eyes at 0 h (10:00 AM). Assessment of IOP was conducted by a researcher who was unaware of the treatments at 0 h immediately before dosing and 2 h, 7 h, 23 h, and 47 h post-treatment. The arrow indicates when the treatment was applied. Error bars represent SEM of IOP values (n=8). An asterisk indicates p<0.05 between the two groups by paired Student’s t-test.
