A study to determine whether a patient's range of vision test results improve after their eye pressure is lowered by 30% or more by testing on a new machine called the Accumap and how to learn how much the Accumap's results change from one test to another within the same person.
The investigators believe that Multifocal VEP readings (Accumap)(and therefore visual function and ganglion cell function) improve after acutely lowering intraocular pressure.

|Actual Study Completion Date :||January 2007|
Patients that have medical intervention in an attempt to lower intraocular pressure (oral or topical)
Patients who have received no intervention
- lowering of intraocular pressure will cause an acute improvement in MfVEP (multifocal visually evoked potential) amplitude readings [ Time Frame: 1 day ]
