Retinal fixation behavior in human albinos.
The retinal fixation behavior of 17 albinos was examined whilst they fixated a stationary target. An optical system was arranged so that the motion of the target on the retina, due to the nystagmus, could be video-recorded. Eye movements were monitored simultaneously. Eight of the 17 subjects were judged to use consistently a retinal location compatible with the anatomical position of the fovea. The implications of this for subjects with foveal hypoplasia are discussed.
