Inferior oblique muscle location after enucleation and evisceration.
OBJECTIVE
To report the location of the inferior oblique muscle after enucleation without primary attachment of the muscle to the orbital implant and after evisceration.


METHODS
Interventional case series. Retrospectively, eight orbital magnetic resonance imaging (MRI) studies were analyzed, four after enucleation and four after evisceration, to assess the position of the inferior oblique muscle relative to the orbital implant and the point of insertion.


RESULTS
In the enucleation patients, the inferior oblique muscle was anteriorly displaced and the muscle appeared to insert into an inferior subconjunctival scar mass in three of the four patients. In all four of the evisceration patients, the inferior oblique muscle appeared normally positioned and inserted onto the implant in the normal location.


CONCLUSIONS
Enucleation without suturing of the inferior oblique muscle to the implant is associated with healing in an abnormal anterior location and into an inferior subconjunctival scar mass. Evisceration does not appear to disrupt the normal position or insertion of the inferior oblique muscle.
