About this study
Official title: Anatomical Assessment of Orbital Contents on Imaging
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Oculomotor muscles study | Not described | |
| Intraorbital content | Not described |
What is being measured
The primary outcome is the main question the study is designed to answer.
Intra- and inter-observer reproducibility of oculomotor muscle anatomical criteria in imaging
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).
Measured: 1 year.
Secondary outcomes (1)
Reproducibility of measurements of optic nerve size and orbital fat in imaging
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).
Measured: 1 year.

Questions about this trial
What is this clinical trial studying?
An observational study of Anatomical Study, run by University Hospital, Brest at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 22 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does the primary outcome measure?
Intra- and inter-observer reproducibility of oculomotor muscle anatomical criteria in imaging (time frame: 1 year.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
