Primary Outcome Measures :
  1. Intraocular Pressure (IOP) for a 24-Hour Period at Week 4 [ Time Frame: Week 4 ]
    IOP for a 24-hour period separated into diurnal(7AM-11PM or awake period) and nocturnal (11PM-7AM or sleep period) at week 4. IOP is a measurement of the fluid pressure inside the eye. Measurements of IOP were taken in the sitting and supine (laying down face up) body positions during the 16-hour diurnal (awake) period and in the supine position during the 8-hour nocturnal (sleep) period.


Secondary Outcome Measures :
  1. Change From Baseline in Intraocular Pressure (IOP) for a 24-Hour Period at Week 4 [ Time Frame: Baseline, Week 4 ]
    Change from baseline in IOP for a 24-hour period separated into diurnal (7AM-11PM or awake period) and nocturnal (11PM-7AM or sleep period) at week 4. IOP is a measurement of the fluid pressure inside the eey. Measurements of IOP were taken in the sitting and supine (laying down face up) body positions during the 16-hour diurnal (awake) period and in the supine position during the 8-hour nocturnal (sleep) period. A negative number change from baseline indicates an improvement.

  2. Ocular Perfusion Pressure (OPP) for a 24-Hour Period at Week 4 [ Time Frame: Week 4 ]
    Ocular perfusion pressure (OPP) calculated for a 24-hour period separated into diurnal (7AM-11PM or awake period) and nocturnal (11PM-7AM or sleep period) at week 4. Ocular perfusion pressure is blood pressure minus the intraocular pressure, which is a measurement of the fluid pressure inside the eye. Measurements of IOP and blood pressure were taken in the sitting and supine (laying down face up) body positions during the 16-hour diurnal (awake) period and in the supine position during the 8-hour nocturnal (sleep) period.

  3. Change in Ocular Perfusion Pressure (OPP) Over a 24-Hour Period at Week 4 [ Time Frame: Week 4 ]
    Change in ocular perfusion pressure (OPP) calculated over a 24-hour period separated into diurnal (7AM-11PM or awake period) and nocturnal (11PM-7AM or sleep period) at Week 4. Ocular perfusion pressure is blood pressure minus the intraocular pressure, which is a measurement of the fluid pressure inside the eye. Measurements of IOP and blood pressure were taken in the sitting and supine (laying down face up) body positions during the 16-hour (awake) period and in the supine position during the 8-hour nocturnal (sleep) period.
