Acquired homonymous visual field defects (HVFDs) result in significant disability, reducing quality of life. Spontaneous recovery occurs within the first months, then the likelihood of vision recovery decreases, making rehabilitation necessary. HVFD
create a 2-D VEP map. This is achieved by using a time-varying complex signal pattern and complex signal analysis. It has been shown to correlate withvisual field defectsin other optic neuropathies[22,23]. A literature review, however, did not locate studies using this technique in ...

HMR currently quotes a prevalence of visual field defects in adults receiving VGB of about 30% (company communication). A recent study reports a prevalence of 29% in a survey of 41 pat·lents.21 The results of a recent general practitioner questionnaire suggest an incidence of VGB-associated ...

Patients with MS presented greater thinning of the RNFL in all retinal areas compared to controls, excluding the upper nasal field. This loss was especially remarkable at the lower temporal level, with a decrease in thickness of ?1.796μm/year in MS patients compared to ?0.547μm/year in ...
72Different studies recommend different electrode positions and strategies for analyzing mfVEP waveforms and have clearly stated that mfVEP assessment is dependent on electrodeposition.73,74mfVEP plays a useful role in identifying local visual field defects but it must be interpreted with caution as it...
An increased latency of VEP wave forms is commonly found in multiple sclerosis. …show more content… Flash VEP applies a diffuse flash stimulation over the retina which may overlook localized visual defects. It has high variability across population which results in poor disease sensitivity. The ...
