Abstract

Objective: Exotropia is a condition in which there is a misalignment of the visual axes and a difference in eye symmetry. This can lead to diplopia (double vision) and a decrease in visual acuity. In some cases, the head may also change position to help the affected eye focus on distant objects. The main concerns for patients with exotropia are visual acuity, the appearance of their eyes, and cosmetic postures.
Methods: This study examines the success rates of surgery and changes in visual acuity for 44 patients who underwent exotropia surgery.
Results: Of the patients who had recession-resection surgery, 79.1% were successful, 12.5% had partial success, and 8.4% were unsuccessful. For those who had bilateral recession surgery, 70% were successful, 5% had partial success, and 25% were unsuccessful. There was a statistically significant difference in preoperative visual acuity between the two groups. After surgery, there was a significant improvement in visual acuity for both groups. 
Conclusion: The majority of patients (70.4%) undergo this surgery for cosmetic reasons rather than for improved visual acuity. There was no significant difference in postoperative results between the two groups in terms of shift values.
