Many barriers to successful visual field testing exist, but much of the frustration encountered can be avoided by following some basic guidelines and using all the technological features todays devices offer. From this baseline, GPA is able to provide both event- and trend-based progression analysis on future tests (. Am J Ophthalmol. 22. Conversely, you would hold testing on a healthy 40-year-old patient to a high degree of specificitythe condition is much less commonly seen in that population and the diagnosis carries with it the potential of significant burden due to the long life expectancy.

Extensive RNFL loss (~30%) is necessary to produce a visual field defect.22,23 An individual (especially a patient with a large optic nerve) may have as much as one third of her or his RNFL deteriorate while still maintaining green normative levels on OCT analysis (this is often referred to as green disease).24 A recent study reported the highest correlation between progression on OCT and visual field to occur at a 10m RNFL loss on SD-OCT.25 For many patients, advanced glaucomatous optic atrophy will result in a severely depressed RNFL that does not allow for proper detection of progression. Understand the roles of the technician and physicianIts important that the staff and physician maintain positive attitudes about the value of perimetry to encourage the patient to provide optimal results during testing.8 Although the physician should not administer the test personally, they should take time during the exam to stress to the patient the importance of perimetry in the management of their ocular disease.
