Does Lowering Eye Pressure Affect the Results Obtained From Objective Visual Field Testing?
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.
|Study Design:||Observational Model: Case-Only
Time Perspective: Prospective
|Official Title:||Effect of Acutely Lowering Intraocular Pressure on Multifocal Visual Evoked Potential Testing|
- lowering of intraocular pressure will cause an acute improvement in MfVEP (multifocal visually evoked potential) amplitude readings [ Time Frame: 1 day ] [ Designated as safety issue: No ]
|Study Start Date:||October 2004|
|Study Completion Date:||January 2007|
|Primary Completion Date:||January 2007 (Final data collection date for primary outcome measure)|
Patients that have medical intervention in an attempt to lower intraocular pressure (oral or topical)
Patients who have received no intervention
