. 2001 Feb;
41(4):521-8.
PMID: 11166054
The perception of image smear for a target flashed during a saccade is attenuated if the target remains visible after the eye movement ends, a result that has been attributed...

. 2001 Jan;
77(11):573-81.
PMID: 11138830
Comparisons between the visual performance of persons with congenital nystagmus (CN) and normal observers under conditions of similar retinal image motion reveal the extent to which the nystagmus-induced image motion...

Optom Vis Sci
. 2000 Dec;
77(10):524-30.
PMID: 11100890
We examined the effects of simulated dioptric blur on the degradation of visual acuity using digitally filtered letters. Four types of digital filters were applied to 5 letters (C, D,...

Psychol Rev
. 2000 Aug;
107(3):556-77.
PMID: 10941280
Backward-masking functions have been hitherto categorized into two types, commonly named Type A and Type B. The analysis of a model of Retino-Cortical Dynamics produces the prediction that spatially localized...

Aitsebaomo A, Bedell H
Optom Vis Sci
. 2000 Jul;
77(6):321-30.
PMID: 10879789
Saccades are rapid, conjugate eye movements that shift the foveas onto peripheral targets of interest. However, the initial saccades to a peripheral pair of targets have been reported to direct...

. 2000 Jun;
17(6):947-54.
PMID: 10850464
Previously we showed that thresholds for abutting Vernier targets are unaffected by motion, as long as the targets are processed by the same spatial-frequency channel at each velocity and remain...

Reich L, Bedell H
Optom Vis Sci
. 2000 Jun;
77(5):270-5.
PMID: 10831217
Background: Patients with macular disease may image optotypes at a peripheral retinal locus during visual acuity testing. In this study, we asked if the relative legibility and confusions between letters...

Ukwade M, Bedell H
Vision Res
. 1999 Sep;
39(17):2963-73.
PMID: 10492822
Despite rapid oscillations of the eyes, visual acuity is close to normal in many observers with congenital nystagmus (CN). This study investigated whether binocular hyperacuity thresholds are also close to...

Vision Res
. 1999 Jun;
39(14):2349-60.
PMID: 10367056
Vernier acuity is a form of hyperacuity in which the threshold offset between a test object and a reference object is smaller than the size of a foveal cone. Because...
