| Abstract |
|
This study is designed to determine the frequency of amblyopia and sensory fusional anomaly in intermittent exotropia and the relationship between amblyopia and sensory fusional anomaly. Ninety eight intermittent exotropic patients were selected and using full corrected visual acuity, the selected patients were divided into amblyopia group and non-amblyopia group. Then, refractive errors, Bagolini lens test, Worth 4 dot test and stereoacuity test were measured and these values were statistically analyzed. The frequency of amblyopia among intermittent exotropia group was 14 patients[14.3%]. Anisometropia among amblyopia group was 6 patients[43.9%] and among non-amblyopia group was 6 patients [7.1%]. Anisometropia was statistically meaningful in amblyopia group compared with non-amblyopia group[p<0.002]. Sensory fusional anomaly among amblyopia group showed 50%at near distance and 64.3%at far distance, among non-amblyopia group 10.7% at near distance and 20.2%at far distance in Worth 4 dot test. Therefore, it appeared to be statistically meaningful in amblyopia group compared with non-amblyopia group[p<0.001, p<0.002]. Sensory fusional anomaly among amblyopia group showed 35.7%and among non-amblyopia group 14.3%in Bagolini lens test, it appeared to be statistically not meaningful[p>0.064]. In stereoacuity, it decreased statistically meaningful when amblyopia[p<0.003] or sensory fusional anomaly[p<0.019]were present. |
