A closer look at the inferior oblique recession surgery

The inferior oblique muscle plays a crucial role in ocular motility, primarily responsible for extorsion, elevation, and abduction of the globe. The muscle has a unique anatomical course that makes surgical manipulation both technically nuanced and critical in the management of certain strabismus conditions like primary or secondary inferior oblique overaction, dissociated vertical deviation, or V-pattern strabismus. This video article demonstrates a standardized technique for inferior oblique muscle recession, a commonly performed weakening procedure in strabismus surgery. The step-by-step surgical approach are clearly outlined, beginning from conjunctival incision to disinsertion and reattachment of the muscle at a recessed site. Intraoperative challenges include the risk of leaving residual muscle fibers attached, which may result in under correction or recurrence; inadvertent scleral perforation, with a risk of retinal or macular injury and significant bleeding resulting from damage to the vortex veins or adjacent vascular structures. Due to the proximity of the inferior oblique muscle insertion to the posterior pole, particular caution is required to prevent inadvertent injury to the macular region during surgery.
