Imaging in strabismus re-operations

Purpose: 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. Methods: 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. Results: Imaging enables a more predictable surgical course and better informs patients about procedure outcomes. Discussion: Key steps include selecting the optimal modality, understanding relevant anatomy, and using appropriate probes or sequences for accurate acquisition and interpretation. Conclusions: This review details nuances of each technique and their utility in strabismus reoperation scenarios.
