Field enhancementOpinion statementA 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 ...
An altitudinal visual field defect is a condition in which there is defect in the superior or inferior portion of the visual field that respects the horizontal midline. The altitudinal defect can be unilateral or bilateral. The most common cause of this type of nerve fiber layer visual field de...
Disease within this tract causes an incongruous homonymous field defect in visual perimetry. The optic radiations are a continuation of the fibres from the lateral geniculate tracts and terminate in the cortex of the occipital lobes. These nerve fibres are divided into superior, central, and ...
Rehabilitation of chronic post-stroke visual field defect with computer-assisted training: a clinical and neurophysiological study. PURPOSE\nOur aim was to study whether homonymous visual field defects could be restored in chronic stroke patients (N = 5) using computer-assisted training, and whether ...
• A homonymous visual field defect, typically caused by a lesion in the parieto-occipital region, is often associated with palinopsia. • Etiologies include drugs, psychiatric conditions, seizures, metabolic disorders, focal brain lesions, migraine, and multiple sclerosis. Red Flags Misalignment...
training during a six-month period. To evaluate the treatment effect, the size of the VF defect before and after treatment was quantified with the help of a scanning laser ophthalmoscope. In none of the patients, however, an explicit homonymous change of the absolute field defect border was ...

Goldmann visual fields confirmed a left homonymous hemianopia and constriction of the visual field 8 months ago and a visual acuity of 6/12 in each eye. Target 14e was detected at 30° temporally in the right eye and 20° nasally in the left eye. With target III4e the left nasal ...
