title: Clinical Preoperative and Postoperative Symptoms of Exotropia.
abstract: OBJECTIVE
  To examine clinical preoperative and postoperative symptoms and changes in exotropia according to constancy and age.
  
  
  METHODS
  A survey was conducted of 50 patients on the day before and 1 month after exotropia surgery. Survey results were analyzed by type of exotropia at presentation and age. Changes in subjective symptoms from preoperatively to postoperatively were examined for stereopsis (5 items), asthenopia (5 items), and appearance (5 items). Each item was rated on a 5-point scale ranging from 0 to 4.
  
  
  RESULTS
  The mean age of the 50 patients was 10.6 ± 7.75 years, and there were 21 (41.2%) males and 29 (56.9%) females. Thirty-two patients with intermittent exotropia had no significant improvement in the stereopsis or asthenopia symptoms. However, they showed significant (P < .05) improvement in the appearance symptoms of squint and out of focus. Eighteen patients with constant exotropia showed significant improvements in the symptoms of tripping over objects or running into a wall in stereopsis and of squint and out of focus in appearance (P < .05). Postoperatively, all patients had significant improvement in appearance-related symptoms regardless of age (P < .05).
  
  
  CONCLUSIONS
  Patients with constant exotropia had improved symptoms in stereopsis, asthenopia, and appearance after surgery. Appearance was improved regardless of the type of exotropia or age.
