Abstract
Overaction of the inferior oblique muscle is a common aspect of new and recurring cases of strabismus. Children with infantile esotropia often develop overelevation in adduction. Incomitant eso- and exo-deviations in children and adults frequently show V, X, or Y patterns with overelevation. Weakening of one or both inferior oblique muscles may be indicated in all these conditions. Aim of the Work: To compare the outcome of inferior oblique muscle weakening by graded anterior transposition or myectomy in primary and secondary inferior oblique overaction. Methods: This randomized Prospective clinical study will be conducted on a total of 30 patients with IOOA in one or both eyes divided into two main groups and be matched according to age and sex. Results: There were no significant differences in hypertropia between Group A and Group B, both preoperatively and postoperatively, across all measures (primary gaze, contralateral gaze, ipsilateral gaze, and tilt). Both groups showed significant improvements in hypertropia from pre- to postoperative assessments, indicating the effectiveness of the surgical approaches. Group A demonstrated better postoperative outcomes in primary gaze and contralateral tilt, with significantly lower residual hypertropia in primary gaze. Group B showed greater improvements in ipsilateral tilt, although this was not statistically significant. Both groups had comparable results in other areas, with no clear superiority of either group.
