  • Title: VER analysis of the chiasmal syndrome.
    Author: Müller-Jensen A, Zschocke S, Dannheim F.
    Journal: J Neurol; 1981; 225(1):33-40. PubMed ID: 6164754.
    Abstract:
    In the evaluation of chiasmal syndromes the efficiency of VER analysis could be enhanced by separate stimulation of the temporal and nasal half of the visual field. The report is based on data of 27 patients with compressive chiasmal lesions. VER findings have been correlated with the visual fields meticulously plotted with a Tuebingen perimeter and/or an Octopus computer perimeter. Alterations in both parameters have been graded in three groups. The degree of alteration correlated fairly well for both test procedures. Not only was a reduction of VER amplitude observed for the affected hemifield, but a latency delay as well. A discrete damage in the nasal hemifield may be detected even earlier by means of VER half field analysis than by conventional subjective perimetry.
