Abstract

PURPOSE
To evaluate the factors influencing the direction of sensory strabismus and the consequent surgical outcomes. METHODS: We retrospectively reviewed the medical records of 150 sensory strabismus patients who had undergone surgery. Consisting of 38 esotropes and 112 exotropes. Parameters considered were the cause of vision loss, the age at vision loss, the refractive error of the sound eye, the interorbital distance in the posteroanterior view of the orbit, the deviation angle at postoperative 6 months and 1 year. Patients were excluded if the cause of vision loss was strabismic amblyopia. RESULTS: The major causative factors of sensory strabismus were corneal opacity (26.7%) followed in frequency by cataract (22.7%), and optic nerve disorder (15.3%). The age at vision loss, the refractive error of the sound eye, and the inner and outer interorbital distance were statistically significant among the considered factors in determining the direction of sensory strabismus. At postoperative 6 months, 69.3% of the patients maintained the alignment within 10 PD of orthotropia and 70.4% at 1 year. CONCLUSIONS: We considered that the age at vision loss, the refractive error of the sound eye, and the inner and outer interorbital distance could play a role in determining the direction of sensory strabismus. In spite of the deficit of sensory fusion, the surgical outcomes of sensory strabismus remained favorable at 1 year after surgery.
