title: Anomalous motion VEPs in infants and in infantile esotropia.
abstract: Visual evoked potentials (VEPs) were recorded monocularly in response to vertical gratings that underwent oscillatory apparent motion at a temporal frequency of 10 Hz. In normal infants 6 months or younger and in patients with a history of constant strabismus onset before 6 months of age, the oscillatory motion VEP contains a prominent first harmonic component that is temporally 180 degrees out of phase in the two eyes. This pattern is not seen in normal adults and is consistent with the presence of a nasalward/temporalward asymmetry of cortical responsiveness in infants and in patients with early onset strabismus.
