Corresponding retinal nerve fibres begin their path in the eyes and end in a single visual cortical cell. Because of this arrangement, lesions in the anterior visual pathway produce incongruent visual field defects and in the posterior pathway congruent field defects. The lateral geniculate body is ...

MRI images are correlated with perimetric findings in order to demonstrate localization of lesions in the visual pathway. This may serve as a valuable reference tool to clinicians and radiologists in the early diagnostic process of differentiating causes of various visual field defects in daily ...

visual field defectSince 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...
Although anomalies affecting the optic nerve head are usually clinically innocuous, they can sometimes cause significant symptoms and lead to visual loss. ... DJ Apple,MF Rabb,PM Walsh - 《American Journal of Ophthalmology》 被引量: 336发表: 1984年 Visual Field Defects in Idiopathic Intracranial ...
lesions (< six months; n = 3) was critically investigated by treating only one part of the defective field at a time and comparing the changes in the treated and non-treated VF part (within-patient control). Of the patients (#3, 4, 17) with fresh lesions, no VF improvement was ...
These findings demonstrate that certain fibers from the ipsilateral eye travel more anteriorly and laterally in Meyer's loop, and support the hypothesis that visual field defects due to anterior retrogeniculate lesions are relatively incongruous because of anatomic differences in the afferent pathways. ...
C H A P T E R 56 Visual Field Testing I. INTRODUCTION Abnormalities of peripheral vision are called visual field defects. These defects, many of which can be detected at the bedside, provide important clues to the diagnosis of lesions throughout the visual pathways—the ret- ina, optic...
