Further study details as provided by University of Colorado, Denver:

Primary Outcome Measures:
  • Changes in Intraocular Pressure [ Time Frame: Every 2 hours for 24 hours ]
    To determine the 24-hour intraocular pressure lowering effect of Travatan Z

Secondary Outcome Measures:
  • Intraocular Pressure Change Duration [ Time Frame: 72 hours ]
    Elucidate the duration of effect from Travatan Z administration which may lead to more efficient dosing regimens

Enrollment: 40
Study Start Date: April 2012
Study Completion Date: April 2013
Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Detailed Description:
The investigators hypothesize that Travatan Z will significantly lower intraocular pressure and increase ocular perfusion pressure during both the diurnal and nocturnal period, during a 24-hour evaluation, compared to baseline. The investigators further hypothesize that the medication effects will persist at 72 hours after discontinuation of the drug.
