[HTML][HTML] The attenuation surface for contrast sensitivity has the form of a witch's hat within the central visual field
Abstract Abstract: Abstract Over the full visual field, contrast sensitivity is fairly well described
by a linear decline in log sensitivity as a function of eccentricity (expressed in grating cycles)…

[HTML][HTML] The shift in ocular dominance from short-term monocular deprivation exhibits no dependence on duration of deprivation
Deprivation of visual information from one eye for a 120-minute period in normal adults
results in a temporary strengthening of the patched eye’s contribution to binocular vision. This …

[HTML][HTML] Suppression rather than visual acuity loss limits stereoacuity in amblyopia
AL Webber, KL Schmid, AS Baldwin… - … & Visual Science, 2020 - iovs.arvojournals.org
Purpose: To investigate the influence of interocular suppression and visual acuity loss on
stereoacuity in observers with and without abnormal vision development from strabismus or …

[HTML][HTML] Cholinergic potentiation alters perceptual eye dominance plasticity induced by a few hours of monocular patching in adults
Y Sheynin, M Chamoun, AS Baldwin… - Frontiers in …, 2019 - frontiersin.org
A few hours of monocular deprivation with a diffuser eye patch temporarily strengthens the
contribution of the deprived eye to binocular vision. This shift in favor of the deprived eye is …

Effects of simulated anisometropia and aniseikonia on stereopsis
Purpose Stereopsis depends on horizontally disparate retinal images but otherwise
concordance between eyes. Here we investigate the effect of spherical and meridional simulated …

[HTML][HTML] Ocular dominance plasticity: inhibitory interactions and contrast equivalence
Brief monocular occlusion results in a transient change in ocular dominance, such that the
previously patched eye makes a stronger contribution to the binocular percept after occlusion. …

[HTML][HTML] Ocular dominance plasticity: a binocular combination task finds no cumulative effect with repeated patching
Short-term monocular deprivation strengthens the contribution of the deprived eye to binocular
vision. This change has been observed in adults with normal vision or amblyopia. The …

[HTML][HTML] Visual plasticity and exercise revisited: no evidence for a “cycling lane”
Experiments using enriched environments have shown that physical exercise modulates
visual plasticity in rodents. A recent study (Lunghi & Sale, 2015) investigated whether exercise …

[HTML][HTML] Assessment of stereovision with digital testing in adults and children with normal and impaired binocularity
J Tittes, AS Baldwin, RF Hess, L Cirina, Y Wenner… - Vision Research, 2019 - Elsevier
New digital approaches allow stereovision to be assessed with greater precision than
current clinical stereo tests. Those current tests present a relatively narrow range of stimulus …

[HTML][HTML] Amblyopic stereo vision is efficient but noisy
People with amblyopia demonstrate a reduced ability to judge depth using stereopsis. Our
understanding of this deficit is limited, as standard clinical stereo tests may not be suited to …
