Abstract

Infantile esotropia is a constant convergent strabismus that occurs early in life and affects a considerable number of infants (Mohney et al., 1995). This condition can be accompanied by several motor (crossed fixation, dissociated vertical deviation, etc.) and sensorial abnormalities (absence of binocular vision and stereopsis). Early surgical eye alignment is recommended to avoid permanent sensorial deficits, mainly in binocular vision. Recent studies of patients with infantile esotropia have reported nasalward/temporalward bias in OKN responses, smooth pursuit, VEP motion responses, and motion perception (Demer and von Noorden, 1988; Tychsen and Lisberger, 1986; Norcia et al., 1991).
