Does Lowering Eye Pressure Affect the Results Obtained From Objective Visual Field Testing?

Completed

Conditions studied: Glaucoma

In brief

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.
