This is a single-center retrospective study based on existing data. The study focuses on the anatomical content of the orbit, and in particular the anatomy of the oculomotor muscles in the orbit, which are involved in eye movements. There are 6 of these muscles, with the superior, inferior, medial and lateral rectus muscles, and the superior and inferior oblique muscles in each orbit. The study also covers the anatomy of the optic nerve and orbital fat.

Knowledge of the anatomy and biometry of the oculomotor muscles, and of methods for assessing these muscles, has implications for clinical, medical and surgical practice.
