Case 2: Comparing a SITA-SWAP Test with Standard White-on-White Testing
Figure 9.7a Glaucomatous Visual Field Defect Discovered with SITA-SWAP
In this case, an early paracentral visual field defect is seen with SITA-SWAP in the superior hemifield
of the patient's right eye. The GHT indicates “Outside Normal Limits”. Both the MD and PSD global
indices are flagged, with the PSD marked at the P < 5% limit.
This printout is a good example of why you shoul
d avoid referring to the grey tone diagram with
SWAP testing. A larger area of the superior visual field appears to be affected. Yet, the Total and
Pattern Deviation probability plots show a much smaller but important area to be significantly
depressed relative to normal limits.
