Abstract

Background/Aims: Consecutive exotropia is a manifest that develops in a formerly esotropic patient either spontaneously or after optical or surgical treatment for esotropia. It has been reported in 3-29% of patients. Consecutive deviations are generally considered as complications of strabismus surgery. The purpose of this study is to determine the incidence of consecutive exotropia following successful surgical correction of childhood esotropia and identify factors associated with its development.

Methods: A descriptive, retrospective study was carried out through review of 117 cases (55 males, 62 females) having age variation from 1-18 years, who were operated on for congenital esotropia between March 2010 and November 2017 and had follow-up for a period of 3 years. Variables used were: age at surgery, patient sex, bilateral medial rectus recession, length of recession, degree of preoperative deviation, presence of inferior oblique over-action and post-op assessments.

Result: The Incidence of Consecutive Exotropia following surgical correction of childhood Esotropia was found to be 13.7 (16/117), which is correlated with previous studies. Among risk factors, the Length was the only significant factor that decreased the risk of developing consecutive Exotropia by 0.254 (P = 0.017). Age at surgery, Pre-operation Angle and Bilateral IO recession didn’t show any association with the risk of developing consecutive Exotropia.

Conclusion: There was a statistical significance of consecutive exotropia development in patients in regard to length of medial rectus muscle recession, while age at surgery, gender, preop angle prism diopter and inferior oblique overaction had no role in affecting the occurrence of consecutive exotropia.
