Lateral dominance and visual evoked potentials in albinos.
Lateral preferences for the use of eye, hand, and foot were assessed in 17 male and female albino subjects, aged 15 to 52 yr. Visual evoked potential (VEP) recordings suggested that optic fibres were abnormally decussated in these subjects, as others have shown. Fewer albino subjects showed the lateral preference for the use of hand/eye and foot/eye similar to that of normals. It is postulated that the abnormal decussation of optic fibres may underlie the reduced preference for the use of the same hand and eye, and foot and eye, in albinos.
