Citation: Xi J, Jia W-L, Feng L-X, Lu Z-L, Huang C-B. Perceptual learning improves stereoacuity in amblyopia. Invest Ophthalmol Vis Sci. 2014;55:2384–2391. DOI:10.1167/ iovs.13-12627 PURPOSE. Amblyopia is a developmental disorder that results in both monocular and binocular deficits. Although traditional treatment in clinical practice (i.e., refractive correction, or occlusion by patching and p...
متن کاملPerceptual learning improves visual performance in juvenile amblyopia.
PURPOSE To determine whether practicing a position-discrimination task improves visual performance in children with amblyopia and to determine the mechanism(s) of improvement. METHODS Five children (age range, 7-10 years) with amblyopia practiced a positional acuity task in which they had to judge which of three pairs of lines was misaligned. Positional noise was produced by distributing the ...
متن کاملPerceptual learning improves contrast sensitivity and visual acuity in adults with anisometropic amblyopia
To evaluate the effects of perceptual learning on contrast-sensitivity function and visual acuity in adult observers with amblyopia, 23 anisometropic amblyopes with a mean age of 19.3 years were recruited and divided into three groups. Subjects in Group I were trained in grating detection in the amblyopic eye near pre-training cut-off spatial frequency. Group II received a training regimen of r...
متن کاملPerceptual learning improves contrast sensitivity, visual acuity, and foveal crowding in amblyopia.
BACKGROUND Amblyopic observers present abnormal spatial interactions between a low-contrast sinusoidal target and high-contrast collinear flankers. It has been demonstrated that perceptual learning (PL) can modulate these low-level lateral interactions, resulting in improved visual acuity and contrast sensitivity. OBJECTIVE We measured the extent and duration of generalization effects to vari...
متن کاملImproving vision in adult amblyopia by perceptual learning.
Practicing certain visual tasks leads, as a result of a process termed "perceptual learning," to a significant improvement in performance. Learning is specific for basic stimulus features such as local orientation, retinal location, and eye of presentation, suggesting modification of neuronal processes at the primary visual cortex in adults. It is not known, however, whether such low-level lear...
