Abstract

Purpose: It is accepted that vernier acuity reflects=20 cortical processing (Levi et al 1985). This has been = measured=20 as low as 5.1 arcsec (Li et al 2000). Such low = thresholds=20 combined with the resolution limitations of commercially = available=20 CRTs have necessitated large test distances.

We designed a protocol to measure vernier acuity using a CRT = at=20 short test distances.

Methods: A modified contrast masking protocol was used = to=20 display a sub=96pixel offset. The target stimulus was a small = sine=20 wave grating superimposed on a large masking sine wave = grating.=20 Both mask and target had either a Gaussian or square = envelope.=20 The target was moved out of phase by different offsets = relative=20 to the mask. Contrast thresholds were obtained using a QUEST=20 adaptive staircase procedure. Perceived vernier offset was = calculated=20 as follows:

Offset =3D |x =96 3D{pi}=20/2| radians

where x =3D tan=961 {(0.5 + k.cos =D8)/k.sin =D8}, = k is=20 contrast threshold and =D8 is phase offset.

To identify stimuli that provide a valid measure of vernier = acuity=20 the following criteria were applied: i) comparable thresholds = to=20 traditional vernier acuity, ii) plausible measures yielded, = iii)=20 resistance to blur. A variety of parameters influencing = suitability=20 of the stimulus were identified: spatial frequency, type of = mask,=20 size, phase and type of target (Gabor, Gaussian, and = square=96edged=20 targets).

Preliminary investigation isolated four promising stimuli. The=20 following experiments revealed the optimal protocol for = measuring=20 vernier acuity at short test distances.

1) 4 subjects were tested using all four stimuli, each presented = 100 times at 7 different offsets. The pattern of thresholds=20 obtained enabled selection of a single testing protocol, = subsequently=20 referred to as Gabor=96Vernier.

2) The impact of dioptric blur on the Gabor=96Vernier stimulus = and a=20 contrast masking task was evaluated.

3) Gabor=96Vernier thresholds were compared to traditional = vernier=20 acuity measures.

Results: 1) Gabor=96Vernier stimulus parameters: the = mask=20 is a Gabor patch and the target a small Gaussian=96edged = square=20 grating, spatial frequency 1.7 cpd. A target 67.5=B0 out of = phase=20 relative to the mask yielded the most plausible and = repeatable=20 vernier thresholds.

2) The Gabor=96Vernier task produced thresholds more resistant = to=20 dioptric blur than the contrast masking task.

3) Thresholds obtained with the traditional vernier task = compared=20 well to Gabor=96Vernier thresholds. A paired t=96test = revealed no=20 statistically significant difference between the two = thresholds=20 (p=3D0.20).

Conclusions: These results indicate that the = Gabor=96Vernier=20 test will prove to be a novel and reliable method of testing=20 vernier acuity at short test distances.
