A false negative value of 10% to 15% or more is suggestive of inattention in a patient without a significant field defect. If the tests span two or more years, the software will plot a future prediction of progression. The nasal and superior fields are more likely to show early glaucomatous defects. Nerve fiber layer in glaucomatous hemifield loss: a case-control study with time-and spectral-domain optical coherence tomography. Six types of visual field tests 1.

You may dial extension 209 or 238 to speak with someone. 12. From this baseline, GPA is able to provide both event- and trend-based progression analysis on future tests (figure 3). Trend-based progression will display linear regression analysis of VFI. Physicians should continue to encourage patients when subsequent testing is ordered or reviewed. Amsler Grids are just graph paper with a dot in the middle which the patient is supposed to focus on. Appropriate pain management includes Tylenol, ice and ophthalmic antibiotic/steroid ointments.

When altering the stimulus, keep in mind that the normative database, SITA test strategy, and progression analysis will no longer be available. Vertical bars (usually black and white) appear on the perimeter screen. Determining if the rate of progression will affect visual function and quality of life is important when making the decision to proceed with escalating therapy that carries increased risk of side effect. Threshold testing has been the standard for glaucoma care since the mid 1980s, offering many advantages over the older standard of manual kinetic perimetry.1-2. Pain is not associated with either form of AMD. Kinetic perimetry (such as Goldmann perimeter): Moving targets of various light sizes and intensities are shown and the patient indicates when they become visible in the peripheral vision. These artifacts are more common in moderate-high hyperopic corrections and when two trial lenses are used. See additional information.

The eye not being tested will be covered with a patch. This will help establish a rate of progression and identify the roughly one in six glaucoma patients who progress at a dangerously high rate (greater than 2dB per year).

SAP test patterns can be categorized as threshold or screening. Field analysis in glaucoma relies primarily on the 24-2 and 30-2 patterns, as the majority of ganglion cells lie within the central 30 degrees of fixation.3 Use of 24-2 has become increasingly prevalent as the test of choice in glaucoma due to its faster testing time and reduced trial lens and lid artifact errors. 4.
