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.
