Vis ua l field tes ts ZATA Thr es ho ld tes t ZATA (Zippy Adaptive Threshold Algorithm) is a new threshold program that is faster and more accurate than earlier threshold tests (Full Threshold, Fast Threshold). Shorter test times are important in perimetry, as patients find it hard to maintain their attention much beyond three minutes and loss of attention is associated with increased variability.

Hens o n 9000 Per imeter Us er M a nua l M ean Def ec t 3 .2 .4 .1 The Mean Defect value, on the printout, gives the clinician an estimate of the extent of damage. A more negative value indicates a less sensitive eye. Mean Defect values are sensitive to both scotoma and media opacities.

Vis ua l field tes ts Stan dard Dev iation 3 .2 .4 .2 The Pattern Standard Deviation of the defect values is a measure of their variability. Large values are indicative of localised scotoma.
