Results of Bilateral Lateral Rectus Recession for Intermittent Exotropia

Background and Objectives: Early mild esotropia (10-14 prism diopters) following bilateral lateral rectus recession for intermittent exotropia lias been shown to carry the best prognosis in future alignment. The current stud) was designed to establish the relationship between the early and late postoperative alignment. Materials and Methods: Twelve patients undergoing a bilateral lateral rectus recession for intermittent exotropia were prospectively evaluated. Patients were evaluated postoperatively after one day. one week and 6 months following surgery .Esotropia or exotropia deviation less than 10 prism diopter was considered a satisfactory result . Results: In this study all patients were followed for 6 months, and it was observed that an overall 66% of patients achieved a satisfactory alignment at the 6 months. Fifty percent of patients changed alignment status during this time. The average shift for the entire group was 1.75 Aexoshift and was not satisfactorily significant (p> 0.05). Conclusion: Long term alignment success was correlated with 6 months data. It seems that applying fusional power to the patient within these six months for correction of the residual deviation, it will be the most important factor for better results.
