An Anatomical Study of the Inferior Oblique Muscle: The Embalmed Cadaver vs the Fresh Cadaver

Dehiscence attributable to the loss of intermuscular fatty tissue and shrinkage in the postmortem state could be mistaken for actual divided bellies in embalmed cadavers. Future studies should investigate the incidence of multiple insertions of IOs in a large number of fresh cadavers. In addition, ocular surgeons should be aware of the possibility of differences in the insertional anatomy of IOs between the left and right eyes.
