Imaging in strabismus re-operations

<i>Purpose</i>: Accurate identification of extraocular muscle insertions in previously operated muscles, along with defining their positions, caliber, and surrounding structures via pre-operative imaging, aids surgical planning for re-operations. <i>Methods</i>: This narrative review summarizes imaging tools and techniques for strabismus re-operation planning, including anterior segment OCT (AS-OCT), ultrasound biomicroscopy (UBM), CT, and MRI. <i>Results</i>: Imaging enables a more predictable surgical course and better informs patients about procedure outcomes. <i>Discussion</i>: Key steps include selecting the optimal modality, understanding relevant anatomy, and using appropriate probes or sequences for accurate acquisition and interpretation. <i>Conclusions</i>: This review details nuances of each technique and their utility in strabismus reoperation scenarios.
