An Unusual Homonymous Visual Field Defect
Survey of Ophthalmology, 2000A 75-year-old man suddenly became aware of an inferior right homonymous visual field defect. Although static perimetry suggested a lesion of the left lateral geniculate nucleus, kinetic perimetry indicated that the presumed homonymous horizontal sectoranopia noted on static perimetry was actually an incomplete homonymous hemianopia with incomplete ...

Treatment of Homonymous Visual Field Defects
Current Treatment Options in Neurology, 2011A clinical presentation of a retrochiasmal or homonymous visual field defect (HVFD) usually represents a permanent visual impairment. The visual and functional ramifications of HVFD will vary by patient. Comprehensive care-the clinical evaluation and consideration for treatment of HVFD-includes vision rehabilitation provided by optometrists ...

Visual Field Defects in Epidemic Dropsy
Clinical Toxicology, 2006Epidemic dropsy is a multi-system disease involving the cardiovascular, hepatic, renal, ocular and other systems. It is a toxic disease caused by the unintentional ingestion of Argemone mexicana (prickly yellow poppy) seeds as an adulterant of wheat flour or more commonly of cooking oil such as mustard oil.To investigate the occurrence of visual field ...

Ocular Toxoplasmosis and Visual Field Defects
American Journal of Ophthalmology, 1980We studied 34 patients with peripapillary lesions secondary to toxoplasmosis. All patients had visual field defects corresponding to interruption of the nerve fiber layer of the retina. The extent of visual field loss increased with proximity to the disk.

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.

Unperceived Visual Field Defects
Archives of Ophthalmology, 1997I read with interest the article by Wu et al 1 concerning the measurement of visual function and the quality of life in patients with cytomegalovirus retinitis. In this article, the authors reported the results of a questionnaire designed to assess visual symptoms in affected patients, including perception of blurred vision, floaters, blind spots ...

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.

American family physician, 1981
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.
