Aberrant asymmetry in binocular visual function and structure between the strabismic and amblyopic monkeys was closely related, with greater impairment of the left visual pathway.Several similar known mutant genes for strabismus and amblyopia were also identified. In conclusion,natural strabismus and ...
The causes of a visual field defect can greatly vary. Often, there are certain causes associated with the various types of defects. For example, a peripheral visual field defect could be caused by glaucoma or retinal detachment. If there is a central field defect, this could be caused by ma...

The visual defects are mapped by an instrument called a perimeter. The gross defects can be detected by the confrontation method. The defects are described in terms of the loss of visual fields.

Since its introduction in the 19th century perimetry has been used to help localise lesions responsible for visual field defects. In this review the visual field defects produced by lesions at different sites along the neurological visual pathway will be discussed and unusual and challenging visual ...
Compressive lesions of the optic nerve, such as optic nerve glioma, might be another reason for visual loss in children [14]. Although patients with optic pathway gliomas can demonstrate various types of field defects, from generalised depression to hemianopias, about 70% demonstrate a central sc...
Since HVF disorders are often related to visual field defects [10], the hemispherical screen presents the advantage of testing HVF in the region of the visual field that is still intact. Furthermore it allows for consideration of the effects of central vision and peripheral vision while ...
