We assessed whether or not the sensitivity for identifying luminance-defined and contrast-
defined letters improved with training in a group of amblyopic observers who have passed …

Amblyopes show specific deficits in processing second-order spatial information (eg Wong,
Levi, & McGraw (2001). Is second-order spatial loss in amblyopia explained by the loss of …

Amblyopia is a developmental abnormality that results in deficits for a wide range of visual
tasks, most notably, the reduced ability to see fine details, the loss in contrast sensitivity …

Performance for identifying luminance-defined letters in peripheral vision improves with
training. The purpose of the present study was to examine whether performance for …

Amblyopia is characterized by a deficit in identifying small letters (acuity deficit) in the
absence of identifiable ocular pathology. One explanation for this deficit is that the …

Purpose.: Although amblyopia is diagnosed in terms of a monocular letter acuity loss,
individuals typically present with deficits on a wide range of spatial tasks. Many of these …

Amblyopia is a much-studied but poorly understood developmental visual disorder that
reduces acuity, profoundly reducing contrast sensitivity for small targets. Here we use visual …

To test whether first-and second-order stimuli are processed independently in amblyopic
vision, we measured thresholds for identifying a target letter flanked by two letters for all …

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 …

Here, we systematically explore the size and spacing requirements for identifying a letter
among other letters. We measure acuity for flanked and unflanked letters, centrally and …
