  • Title: [Visually evoked cortical potentials (VECP) in patients with doubtful impairment of central vision (author's transl)].
    Author: Groneberg A, Teping C.
    Journal: Klin Monbl Augenheilkd; 1981 Sep; 179(3):173-6. PubMed ID: 7300226.
    Abstract:
    Visual evoked cortical potential (VECP) to non-structured, brightness (luminance) stimuli do not provide an appropriate means for assessing the degree of impaired central vision. In comparison, visually evoked cortical potentials to structured (patterned) stimuli presented by pattern reversal of equal mean luminance are highly susceptible to visual changes caused by reduced central vision. Employing different check sizes, the use of checkerboard pattern reversal VECPs permits, independently of the patient, to assess the impairment of central vision.
