title: Left-handedness in blind and sighted children.
abstract: Rates of left-handedness were compared in 1387 blind and 831 sighted children. The rate in male blind children was higher than in female blind children. The incidence of left-handedness was significantly higher in blind than in sighted children in both boys and girls. The percentages of left-handedness were 18.23% and 17.02% in male and female blind children, and 11.02% and 7.52% in male and female sighted children, respectively. It can be stated that sighting is important in the development of normal typical cerebral lateralisation or hand preference.
