- HFA visual field (24-2 Sita Standard, white on white) result unreliable (based on manufacturer's recommendation), defined as fixation losses \> 20% or false positives \> 33%, or false negatives \> 33%
- Visual field defects consistent with glaucomatous optic nerve damage based on at least one of the following two findings:
- On pattern deviation (PD), there exists a cluster of 3 or more points in an expected location of the visual field depressed below the 5% level, at least 1 of which is depressed below the 1% level;
