Visual evoked potentials (VEPs) induced by brief flashes and electroretinograms (ERGs) were recorded in 15 infants (9 prematures and 6 babies with perinatal cerebral injuries) suffering from important disturbances in their visual behavior (abnormal fixation, cortical blindness). The parallel evolution of the visual symptoms and the electrophysiological signs were studied and a good correlation was observed between these clinical and electrical signs. The authors insist on the clinical and prognostic value of the VEP in this category of infants.
