  • Title: [Pattern electroretinography and pattern visual evoked potentials in maculopathy: a comparison with sensory tests].
    Author: Niermann F, Lorenz R, Heider W.
    Journal: Fortschr Ophthalmol; 1989; 86(1):54-8. PubMed ID: 2722101.
    Abstract:
    The retinal and cortical potentials for pattern reversal were recorded in 58 eyes of 30 patients afflicted with macular disease. The highest incidence of abnormality (79%) was found for the amplitudes P-ERG and P-VECP. Total field EOG and L-ERG were affected less frequently (41% and 25%). The P-ERG amplitude correlated significantly with the sensitivity of the central 10 degrees visual field (static perimetry). The P-VECP threshold check size showed a close correlation with visual acuity. Thus, the recording of pattern-evoked retinal and cortical potentials serves as a supplementary means of assessing types of maculopathy.
