Abstract
Rational testing of visual fields requires a filtering procedure capable of identifying those subjects who need a time-consuming examination in an advanced instrument, and those who do not. Such a procedure must be both quick and trustworthy. The first demand can be realized by reducing the number of tested locations, or by dispensing with exact threshold measurements, or both. Unfortunately, these strategies work directly against the demand of high dependability. A reduction in test locations should be less perilous if the test target is replaced with one that probes function over a larger visual field area than an ordinary perimetric target. Crisper visibility at threshold should also be advantageous, for quicker thresholding. So-called high-pass spatial frequency resolution targets appear promising in these regards [6, 7].
