[Prognostic significance of visual evoked potentials in opacities of the optic media of the eye].

Visual evoked potentials have been recorded in 95 patients with cataracts (60 with senile cataracts and 35 with traumatic ones). No visual evoked potentials could be recorded in 23 patients, 14 of these suffering from glaucomas (primary or secondary). The absence of visual evoked potentials indicates that optico-reconstructive surgery is hopeless.
