Posterior ocular parameters following extraocular muscle surgery: an optical coherence tomography study

Background/Aim: Muscle trauma, vascular injury, and compensatory vasoconstriction during strabismus surgery may cause changes in the choroidal circulation early postoperative period. This study aims to evaluate effect of extraocular muscle on posterior ocular parameters, including central subfield thickness (CST), average retinal (ART), (CT), macular volume (MV). Methods: prospective cohort included 26 eyes strabismic patients who underwent single medial or lateral rectus recession using a fornix-based conjunctival incision. All participants detailed ophthalmologic evaluation, axial length (AL) spherical equivalent (SE), uncorrected (UCVA), best-corrected visual acuity (BCVA). Retinal images were obtained spectral-domain optical coherence tomography (OCT). measurements performed preoperatively repeated 1 week month after surgery. Results: received satisfactory results terms deviation. None showed AL, SE, UCVA, BCVA. No significant differences noted CST MV values (P=0.472 P=0.182, respectively). Although subfoveal CT ART statistically decreases (P=0.012 P=0.046, respectively), no these observed (P>0.05). exist between preoperative, first week, nasal temporal Conclusion: Extraocular with incision is safe procedure for CST, ART, CT, MV.
