PURPOSE To quantify motion sensitivity in patients with infantile esotropia who, as a subgroup, have been previously reported to have abnormal oculomotor control. In addition, to probe abnormal binocular development as a factor underlying abnormal motion perception in infantile esotropia (IE), motion sensitivity was compared among participants with and without stereopsis. METHODS Monocular se...

PURPOSE To investigate nasal-temporal asymmetries in the detection of horizontal motion and in cortical motion visual evoked potential (mVEP) responses in normal infants and children and in patients with infantile esotropia. METHODS Monocular motion-detection thresholds were obtained separately for nasalward- and temporalward-moving random-dot patterns in a forced-choice, preferential-looking...

PURPOSE To elucidate the pathophysiology of dissociated horizontal deviation. METHODS The reversed fixation test was performed prospectively in 28 patients who developed consecutive exotropia following horizontal extraocular muscle surgery for infantile esotropia. All patients were assessed for the presence of adduction weakness, latent nystagmus, dissociated vertical divergence, and neurolog...

PURPOSE Infantile esotropia is associated with abnormal visual development and thus may delay the achievement of developmental milestones. Although early surgery can improve visual function, less is known about its effect on motor development. Here we address whether early surgery can improve motor development. METHODS Recently, our lab devised the Infant Developmental Skills Survey, a 25-ite...

BACKGROUND This is a retrospective study to determine the outcomes of the surgical correction in long-standing infantile esotropia with cross fixation. METHODS Medical charts of a group of patients with esotropia who had cross fixation and underwent surgery for strabismus between January 1991 and December 2004 were reviewed. The mean follow-up time was 4.7 years. Binocularity was measured by ...

Sixteen patients with large angle infantile esotropia with deviations of 80-90 prism dioptres were operated at the age of about 2 years. All patients underwent 8 mm bilateral medial rectus recessions. At the last follow up examination, 6 to 48 months postoperatively (average 16.3 months), successful horizontal alignment was achieved in 12 patients (75%). Four patients (25%) were undercorrected....

AIM To investigate the postoperative eye alignment and binocular visual function after early surgery for infantile esotropia. METHODS Both the postoperative eye position and stereopsis were reviewed using the Titmus stereo test in nine patients who received uniocular medial rectus recession and lateral rectus resection under general anaesthesia before 8 months of age and were followed up for ...
