ABSTRACT Purpose: To conduct a 10-year follow-up on the surgical correction of large-angle esotropia using monocular surgery, verifying surgical stability over time in both adults and children, and investigating the presence of consecutive exotropia among reviewed patients. Methods: The angles of deviation in primary position were measured using prism cover testing in patients with good vision in both eyes and the Krimsky method in those with severe amblyopia. Among the 46 patients who underwent surgery, 40 were evaluated 10 years post-surgery. Student’s t-test and McNemar’s test were used for statistical analyses. Results: No significant differences in the angles of deviation in primary position were found between measurements taken 6 months and 10 years post-surgery (p=0.922), as well as between children and adults (p=0.767). Among the 40 reviewed patients, only five presented with exotropia, all of which were small (the largest being XT 15Δ). Therefore, large consecutive exotropia over time was not observed. Conclusion: Our results suggest that monocular surgery to correct large-angle esotropia using large medial rectus recessions and broad lateral rectus resections was viable and safe in both adults and children over short and long terms.
