Anterior segment optical coherence tomography for the preoperative visualization of extra-ocular muscles in adult patients with strabismus

Abstract

Background: The aim of this study is evaluate the accuracy of AS-OCT as a pre-operative tool to measure extra-ocular muscles insertion distance prior to strabismus surgery. Methods: It was a cross sectional observational study including 35 patients were imaged by AS-OCT and operated upon, intraoperative measurment of MR and LR muscles insertion distance was done. Results: There was a statically significant difference between AS-OCT and intra-operative measurements in case of LR muscle. Conclusion: AS-OCT is a useful non-contact tool in measuring MR muscle insertion distance.
