Pattern- and flash-evoked potentials in patients with dissociated vertical deviation.

Pattern reversal and flash evoked potentials were recorded in 13 children with dissociated vertical deviation. We found no evidence of anomalous responses to pattern reversal half-field stimulation and no asymmetries in flash responses as reported to occur in albinism. However, we found that patients with dissociated vertical deviation had significantly smaller monocular and binocular pattern responses compared to a group of age-matched control subjects.
