The pattern of visual deficits in amblyopia.
Amblyopia is usually defined as a deficit in optotype (Snellen) acuity with no detectable organic cause. We asked whether this visual abnormality is completely characterized by the deficit in optotype acuity, or whether it has distinct forms that are determined by the conditions associated with the acuity loss, such as strabismus or anisometropia. To decide this issue, we measured optotype acui...
متن کاملPrehension deficits in amblyopia.
PURPOSE Visual defects associated with amblyopia have been extensively studied, but their impact on the performance of everyday visuomotor tasks is unclear. This study evaluates eye-hand coordination (prehension) skills in adult amblyopes compared with normal subjects. METHODS Twenty amblyopes (10 strabismic, 10 nonstrabismic) with different degrees of visual acuity loss (mild, moderate, or s...
متن کاملVisual search and spatial deficits
Studies of visual search with patients with spatial attentional deficits have shown that the ability to bind basic features properly and thus to search for the conjunction of two spatially contiguous features is compromised. However, the effect of spatial deficits on feature search is more controversial. Here, we explore questions raised by the neuropsychological literature regarding feature pr...
متن کاملVisual search deficits are independent of magnocellular deficits in dyslexia.
The aim of this study was to investigate the theory that visual magnocellular deficits seen in groups with dyslexia are linked to reading via the mechanisms of visual attention. Visual attention was measured with a serial search task and magnocellular function with a coherent motion task. A large group of children with dyslexia (n = 70) had slower serial search times than a control group of typ...
متن کاملVisual search deficits in Williams-Beuren syndrome.
Williams-Beuren syndrome (WBS) is a rare genetic condition characterized by several physical and mental traits, such as a poor visuo-spatial processing and a relative strength in language. In this study we investigated how WBS subjects search and scan their visual environment. We presented 10 search displays on a computer screen to WBS subjects as well as control subjects, with the instruction ...
