Abstract

Strabismus is the loss of ocular alignment, which can lead to amblyopia, defective binocularity, and defective depth perception.

To assess the results of strabismus surgery among patients older and younger than six years and study the influencing and predictive factors.

Surgical treatment for 202 patients clinically diagnosed with horizontal strabismus aged 4-45 years was carried out in Fallujah Teaching Hospital between September 2021 and October 2022. Surgical outcome was assessed at the end of 6 months post-operatively. Chi-square and Mann-Whitney Univariate tests were performed to evaluate the statistical relationship between pre-operative factors and surgical outcomes.

Overall, the success rate of horizontal strabismus surgery was 68.3% (138 patients), and the rate of success among the esotropia group (55.1%) was better than the exotropia group (44.9%). Among age groups, a higher recorded success rate was for ages above 6 (71.7%). The success rate was higher in males than females (54.3% and 45.7%, respectively). Chi-square and univariate analysis showed a significant association between gender ( < 0.068), refractive error ( < 0.033), and surgical outcome.

Surgical correction of strabismus improved overall ocular deviation and binocular function. Esotropia patients benefited the most compared to exotropia patients.
