Abstract

To assess the surgical outcome of intermittent exodeviation in the form of ocular alignment and stereopsis. MATERIALS AND METHODS: It was a prospective comparative study conducted at a teaching hospital in South India. Preoperative angle of deviation was measured for all patients with intermittent exotropia. Binocular function was measured using worth four dot test and stereopsis was measured using Titmus fly test. They underwent bilateral recession or unilateral recession/resection and were followed up at first week, first month and third month postoperatively. STATISTICAL ANALYSIS: Paired t test and unpaired t test were used. RESULTS: A total of 20 patients were studied. 14 patients underwent unilateral recession/resection and four underwent bilateral lateral rectus resection with medial rectus recession and two underwent bilateral lateral rectus recession/resection. Successful surgical alignment was accomplished in 77.8% of patients after a mean follow-up of 3 months. 85.71% success was seen with unilateral recession/resection, whereas bilateral recession/resection and lateral rectus recession had a success rate 50%. 72.22% patients had 60 arc sec or better stereopsis at three months postoperatively. CONCLUSIONS: Unilateral recession/resection has better outcome compared to bilateral surgery. Surgery for intermittent exotropia can help preserve binocular vision.
