Lateralization of Color Discrimination Performance and Lexical Effects in Patients With Chronic Schizophrenia

open access: yesFrontiers in Human Neuroscience, 2021
Introduction: Patients with schizophrenia experience various visual disturbances. However, information regarding color perception in these patients is rare. In this study, we used a lateralized color search task to investigate whether difference in color

Vigabatrin-Associated Visual Field Defects

open access: yesPediatric Neurology Briefs, 2001
The prevalence, risk factors, and long-term outcome of vigabatrin-associated visual field defects were examined in 60 adult patients with partial epilepsy treated with vigabatrin for 7 months to 14 years at the University of Kuopio Hospital, Finland.

Vigabatrin-Induced Visual Field Defects

open access: yesPediatric Neurology Briefs, 1998
A drug surveillance database at Hoechst Marion Roussel, manufacturers of vigabatrin, identified 92 cases of symptomatic visual field defects associated with vigabatrin (usually as add-on therapy) between 1990 and 1997.

Remaining visual field and preserved subjective visual functioning prevent mental distress in patients with visual field defects

open access: yesFrontiers in Human Neuroscience, 2013
Background: Patients with visual field defects after visual pathway lesion may experience reduced vision-related quality of life (vrQoL). It has not been clarified how vrQoL impairments contribute to vision-related mental distress.Methods: 108 subjects ...

An algorithm for visual fields

open access: yesSurvey of Ophthalmology, 1980
The authors present an algorithm, or sequential strategy, for the performance and interpretation of visual fields. Based on the principle that particular areas of the visual field are relatively vulnerable and that particular defect configurations are relatively more diagnostic, the strategy proposes certain "core maneuvers" for all initial ...

Multi-field visualization [PDF]

open access: yes, 2011
Modern science utilizes advanced measurement and simulation techniques to analyze phenomena from fields such as medicine, physics, or mechanics. The data produced by application of these techniques takes the form of multi-dimensional functions or fields, which have to be processed in order to provide meaningful parts of the data to domain experts ...
