Visual Field testing is done with the latest generation of the Humphrey ® Field Analyzer which is considered the gold standard.
Improved testing reliability is attained through the use of fixation monitoring features that automatically track and align patient head and eye position, alerting operator to patient movement away from the trial lens. A complete library of screening and more detailed tests are available for the detection and evaluation of different disease pathologies.
Computerized analysis software is available to allow deviation fron normal calculations and probability scores. Guided Progression Software (GPA) can predict future visual loss through trend analysis and give an indication of efficacy of treatment. A single number ,the VFI, the visual field index, represents the percentage of visual loss on each visual field.
