Abstract

Purpose: To evaluate the efficacy of medial rectus pulley posterior fixation combined with bilateral rectus recession for patients with intermittent exotropia with high AC/A ratio.

Methods: In this study, we enrolled seven patients with exo-deviation ≥10 prism diopters greater at distance than at near fixation and with a high AC/A ratio who underwent bilateral lateral rectus recession to eliminate the exotropia at distance and pulley posterior suturing on both medial rectus muscles to prevent consecutive esotropia at near fixation.

Results: : Five of seven patients achieved successful surgical results, and one patient required postoperative bifocal correction for postoperative eso-deviation at near fixation.

Conclusions: Bilateral lateral rectus recession with medial rectus pulley posterior fixation for intermittent exotropia with a high AC/A effectively corrected exodeviation at a distance and prevented consecutive esotropia and bifocal lens use.
