Summary: Seventeen infants (7 boys and 10 girls) with visual abnormalities (such as poor tracking and following and nystagmoid eye movement) and occipital slow activities with irregular polyspikes on EEG were studied. Two thirds of the children showed development of West syndrome with hypsarrhythmia on follow‐up EEG. In 1 child, hypsarrhythmia was evident on the follow‐up EEG, but no clinical seizures occurred. Because most of the children in our series developed West syndrome, patients with visual abnormalities associated with occipital EEG discharges in early infancy may be at high risk for West syndrome. Occipital abnormalities in early infancy may relate to the occurrence of West syndrome.
