Abstract
EEG records were obtained from 28 children with severe visual incapacity due to retrolental fibroplasia and from 28 children with normal vision. The age range was 5–14 years. Simultaneous psychological and neurological studies were made. 1. 1. All totally blind children showed abnormal EEG records. There was no relationship between the severity of EEG abnormality and the age of the subject. 2. 2. Six of the subjects showed abnormalities in all lobes. The most common abnormalities were occipital spiking and/or slowing. The spike abnormalities were more prominent in the subjects who were totally blind or had light perception than in those with partial vision. 3. 3. Occipital alpha rhythm was either totally absent or poorly developed in the blind children; whereas, considerably better parietal alpha rhythm was often observed. 4. 4. Despite the high percentage of records showing seizure-like discharges, only four out of 28 subjects had clinical seizures.
