VISUAL DISTORTION IN AMBLYOPIA

Visual distortion in amblyopia.

Monocular spatial distortion in strabismic amblyopia.

We examined monocular spatial vision of strabismic amblyopes by measuring errors of relative directionalization (specifying whether or not two targets are in vertical alignment) and partitioning (equating left- and right-field spaces). Abnormally large errors were made when fixation occurred with the amblyopic eye; these errors did not attributable to reduced acuity, unsteady fixation, or eccen...

Amblyopia: is visual loss permanent?

AIM To ascertain whether recovery of visual function in amblyopic eyes is likely to occur when the fellow eye is lost as a result of age related macular degeneration. METHODS The records of 465 patients with an established diagnosis of age related macular degeneration who had attended a specialist macular clinic between 1990 and 1998 were scrutinised. A full clinical examination and standardi...

Visual Acuity Before and After Occlusion Therapy in Children and Adolescents (Aged 5-13 years) Amblyopia

Purpose: To evaluate the effect of occlusion therapy on visual acuity in children and adolescents (aged 5-13 years) with amblyopia. Methods: This experimental study followed a pretest-posttest design. Totally, 72 people with amblyopic eyes (visual acuity between 20/100 and 20/25) were selected through convenient sampling. The visual acuity was assessed at 1, 3, and 6 months after starting occlu...

Nonveridical visual perception in human amblyopia.

PURPOSE Amblyopia is a developmental disorder of spatial vision. There is evidence to suggest that some amblyopes misperceive spatial structure when viewing with the affected eye. However, there are few examples of these perceptual errors in the literature. This study was an investigation of the prevalence and nature of misperceptions in human amblyopia. METHODS Thirty amblyopes with strabism...
