Acute headache and visual field defect
BMJ, 2012A 79 year old woman developed a sudden onset severe bifrontal headache accompanied by an acute loss of peripheral vision, which she described as tunnel vision, and a subsequent transient reduction in her level of consciousness six days after an elective right total hip arthroplasty.

Visual Field Defects with Vigabatrin
CNS Drugs, 2001Vigabatrin is an antiepileptic drug (AED) that acts as a selective irreversible inhibitor of gamma-aminobutyric acid (GABA) transaminase. In 1997, 3 cases of severe symptomatic and persistent visual field constriction associated with vigabatrin treatment were described.

The detection and analysis of visual field defects allows the practitioner to examine some functions of the central nervous system at the bedside. Cerebrovascular accidents and temporal lobe tumours can be diagnosed easily, as can pituitary lesions.

MINIMAL DEFECTS IN VISUAL FIELD STUDIES
Archives of Ophthalmology, 1949INTRACRANIAL lesions that interfere with the visual pathways will cause defects in the visual fields, the extent depending on the amount of interference. When such interference is great enough, the field defect produced is correspondingly large and is easily elicited with routine perimetric studies and even by confrontation. Since the presence of field

There are four classic types of visual field defects. Altitudinal field defects in which the defect is present above or below the horizontal midline are usually associated with ocular abnormalities. A central scotoma is characteristic of optic nerve disease of macular disease.

Neurological Visual Field Defects
Neuro-Ophthalmology, 2011Since 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 field defects will be highlighted.

Retrogeniculate Visual Field Defects
2010Automated perimetry has changed visual field testing considerably in recent years. What was considered an art has become an exercise in interpreting a set of data points obtained mechanically. Automated perimetry saves ophthalmologists time, which ideally should allow for more visual fields to be obtained on patients with unexplained vision loss ...
