Abstract

PURPOSE
This study was carried out for the clinical analysis of deviation axis of sensory strabismus METHODS: We retrospectively reviewed the medical records of 100 patients who had been diagnosed with sensory strabismus and undergone surgery. Etiology, age at onset of vision loss, duration of vision loss, refraction in sound eye, angle of deviation according to sensory esotropia and exotropia were analyzed. RESULTS: The most common etiology was corneal opacity which occurred in 17 patients (17.0%). Fifteen patients had esotropia and 85 patients exotropia. Esotropia was commonly developed in congenital origin (9 patients, 60%) and under the age of 5 years (12 patients, 80%). Exotropia was commonly developed in acquired origin (68 patients, 80%) and over the age of 6 years (53 patients, 62.4%) (P=0.003). When the refraction in sound eye was hyperopia, esotropia developed in 3 patients (18.8%) and exotropia in 13 patients (81.2%). When the refraction in sound eye was myopia, esotroia developed in 12 patients (14.3%) and exotropia in 72 patients (85.7%). But there was no statistical significance (P=0.445). CONCLUSIONS: Type of horizontal strabismus in sensory strabismus was significantly related to the age at onset of vision loss, but not to the refraction in sound eye.
