Kim, Hee Young; Chang, Bong Leen

Abstract

We retrospectively reviewed the medical records of 282 consecutive patients with the diagnosis of exotropia and analyzed the clinical factors related to amblyopia. The average age was 4.8 years old(138 males, 144 females). The results of analysis run as follows. First, in exotropia, the prevalence of the amblyopia was 19.8%, the detection of exotropia in the group with amblyopia was earlier than the group without (p<0.05), the degree of anisometropia was greater, the prevalence of significant anisometropia(more than 1.0 diopter in spherical equivalent) was higher. Second, The presence of amblyopia and the degree of correction of amblyopia before the surgery did not relate with the surgical success rate. Third, the recurrence rate of cured amblyopia after termination of occlusion therapy was 10.8%, the recurrence rate and the developement of amblyopia after surgery were 11.2%, 5.5% respectively. In orthotropia and esotropia after surgery, the recurrence rate of amblyopia and development of amblyopia were high.
