Anatomical Study
Conditions
Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Intra- and inter-observer reproducibility of oculomotor muscle anatomical criteria in imaging | 1 year. | Evaluate the reproducibility of different oculomotor muscle measurements, such as volume (mm3), surface (mm2) or two-dimensional measurements (mm). Differences to the mean. Intraclass correlation coefficient (ICC). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Reproducibility of measurements of optic nerve size and orbital fat in imaging | 1 year. | Evaluate the reproducibility of different measurements to assess the size of the optic nerve (volume (mm3), surface (mm2), two-dimensional measurement (mm) and intra-orbital fat (mm3). Dfference to the mean. Intraclass correlation coefficient (ICC). |
