The purpose of this research study is to determine the diurnal and nocturnal effects of Travoprost with SofZia (Travatan Z) on intraocular pressure and ocular perfusion pressure. We 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. We further hypothesize that the medication effects will persist at 72 hours after discontinuation of the drug.

Primary Outcome Measures:
  • Intraocular Pressure [ Time Frame: 24 hours ] [ Designated as safety issue: No ]
    To determine the 24-hour intraocular pressure lowering effect of Travatan Z

Secondary Outcome Measures:
  • Intraocular Pressure Change Duration [ Time Frame: 72 hours ] [ Designated as safety issue: No ]
    Elucidate the duration of effect from Travatan Z administration which may lead to more efficient dosing regimens
