EVALUATE THE RESULTS OF INTERMITTENT EXOTROPIA SURGERY IN CHILDREN
Main Article Content
Abstract
Background: Intermittent exotropia progresses worsens and lead to impaired binocular functions. Surgery is to preserve binocular vision, anti-suppression and disorders caused by vergences. However, the proper timing of surgery, restoring binocular functions and postoperation binocular vision therapy/orthoptics are being debated. Aims: to evaluate whether postoperative of binocular functions in children with intermittent exotropia. Methods: A prospective study 44 participants under 16 years of age who underwent strabismus surgery for intermittent exotropia between February and June 2023 at the department of Pediatrics-Ho Chi Minh City Eye hospital. Results: The average age of the participants was 10.07±3.17 years. The surgical success rate (esotropia ≤5 pd to exotropia ≤10 pd) was 79,5%. Positive fusional vergences improved to a good level of 68,2%. Near good sensory fusion was 93.2%, at distance sensory fusion was 54.6%. Near high&morderate stereoacuity was 50% – at distance stereoacuity was 31,8%. Conclusion: Positive fusional vergences maintains binocular alignment after surgery. There is no association between the results of surgical success and the restoration of sensory fusion and stereoacuity.
