Abstract

Eighty children who had horizontal strabismus were examined with Titmus and random-dot stereogram(TNO) for the stereoacuity. The patients were analyzed about visual acuity and types of strabismus. In addition, we also analyzed thirty three patients who received correction surgery for the strabismus for evaluation of the changes of postoperative visual acuity and its relationship to the stereoacuity. The results were as follows: 1. The stereoacuity tested by the TNO was proportional to the change of visual acuity, but that of the Titmus was not proportional. 2. The stereoacuity in the exodeviation was higher than the esodeviation. The stereoacuity in the intermittent exotropia was higher than the constant exotropia, and there was no difference in stereoacuity between the accommodative and nonaccommodative esotropia. 3. The visual acuity was improved postoperatively. 4. The postoperative stereoacuity was also improved. The patients with esodeviation showed more improvement in the stereoacuity compared with that of the patients with exodeviation.
