Prognostic value of the visual evoked response.
29 patients with visual defects have been followed up by serial recording of the visual evoked response (VER). Those patients in whom the VER was initially normal all made a satisfactory visual recovery. In others an initial attenuated response was followed by an improvement in vision and this was accompanied by normalization of the VER. A third group of patients with an initially subnormal VER have remained blind and the VER has shown no improvement.
