Electroretinography (ERG) is an eye test in which electrodes are placed on the cornea to measure electrical responses to light in an effort to detect abnormal retinal function. When severe field loss in advanced glaucoma is present, change to a 10-2 pattern to allow for more accurate assessment of the remaining visual field. Dr. Horton is a staff optometrist at the Cincinnati VA Medical Center.

Event-based progression analysis has been used in several landmark glaucoma clinical trials (such as EMGT, AGIS and CIGTS).18-20 The GPA Change Probability Map displays a point-by-point analysis and indentifies progression if at least three points have worsened (marked as possible progression if repeated in two tests and likely progression if repeated in three tests). With repeat visual field testing, most patients find their ability to maintain a steady straight-ahead gaze improves, thus improving the reliability of the results.
