Forty-three children with different forms of strabismus and 44 normal children were submited to the following tests: Terman-Merrill intelligence scale, form L-M; Goldstein-Scheerer stick test; Bender-Santucci graphic perceptive organisation; Zazzo lateral dominance test; Tyson cross-modality matching test. Children with squint exhibited poorer results with the Terman-Merrill, Goldstein-Scheerer and Tyson tests as compared with normal children. The differences found with the other tests were not significant.
