Abstract:
Intermittent exotropia occurs commonly in Korea and its clinical characteristics are relatively well known. We analyzed the clinical characteristics of intermittent exotropia and studied the relationship among them. We examined 229 patients(92 males and 137 females( who first visited three strabismic clinics. The age of onset, frequency, family history and symptoms of intermittent exotropia were examined. The angle and type of deviation were studied and sensory tests were done. The mean age of onset was 32.4 months and frequency ws 39.1% and family history was 8.7%. Photophobia was the most common symptom of intermittent exotropia. The distant angle of deviation was 26.7 prism diopters in average and the near angle was 25.3 prism diopters in average. The most common type of intermittent exotropia was basic type. followed by simulated divergence excess type, convergence insufficiency type, and divergence excess type. In statistical study, there was no significant relationship among clinical characteristics of intermittent exotroia.
