Abstract

Background: Intermittent exotropia (IXT) is a common form of childhood exotropia, accounting for about 50–90% of all the exotropia and affecting about 1% of the general population. Objective: The purpose of this study was to evaluate difference modalities for treatment of intermittent exotropia either by non-surgical and surgical methods. Patients and Methods: this study included 40 patients of both sexes with exodeviation divided into 2 groups; Group (A): 20 patients subjected to non-surgical treatment and Group (B): 20 patients underwent surgical treatment; bilateral lateral rectus recession (BLR). Results: In non-surgical group the success rate was 55% after 12 months of treatment. Overminus glasses are more effective in control of IXT than part-time occlusion (PTO) and convergence exercise. The success rate was 86%. While the success rate in PTO was 43% and the success rate of convergence exercise was 33%. Poor compliance in PTO and convergence exercise therapy affect the treatment effectiveness. In surgical group (BLR) the success rate was 75%. Under-correction was 20% and the overcorrection was 5%. No complications were found. No lateral incomitance was observed. Conclusion: Surgical method is more effective in treatment of IXT than non-surgical methods, but the non-surgical method is more important in younger children. The over-minus glasses is more effective in treatment of IXT than the other non-surgical method due to poor compliance among children in PTO and Convergence exercise therapy. A larger trial for a longer duration is warranted to assess the effectiveness of different modalities of treatment of IXT
