  • Visual evoked potentials and the localization of visual pathway lesions
    Brecelj, Jelka
    The site of a visual pathway lesion correlates with changes oi the pattern reversal visual evoked potentials (VEPs). Optic nerve. oplic chiasm and the retrochiasmal visual pathway lesions were ... explored by evoking visual potentials with a range of stimulus sizes (full-field, half-field and centralfield). Multichannel recording of VEPs was used. It was seen that certain forms of VEP changes were in relation to the lesion location: impairedfunction of the macular fibres could be associated with the W-shaped waveforms of VEPs in some patients with a history of optic neuritis; dysfunction of the crossed fibres resulted in the crossed asymmetry pattern ofVEPs in compressive lesions of the chiasm; while dysfunctions posterior to bserved in the full-field responses but could only be elucidated in the half-field recordings. VEPs were often more sensitive than the perimetry test,e.g. in chiasmal lesions.
