In a group of 24 children aged from 6 to 26 mths the incidence of Visual Cerebral Impairment has been evaluated by Teller's Acuity Cards, and by electrophysiological tests (Visual Evoked Potentials and EEG Brain Mapping). The cases may be categorized as follows: infantile cerebral palsy: 10 cases; prenatal encephalopathy with developmental retardation: 9 cases; congenital cataract: 5 cases. One or more of the above parameter proved abnormal in 52.6%. Comparatively, the abnormality of the electrophysiological signals was preeminent in Cerebral Palsy, and Visual Acuity deficit in Prenatal Encephalopathies. Asymmetry of electrophysiological signals in patients with congenital cataract could be interpreted as a preclinical signal of incipient amblyopia.
