X-ray Optic Foramen View/ Rhese View Procedure

An X-ray of the optic foramen is a safe and painless way to look at the opening of the optic canal at the base of the skull. This opening is called the optic foramen. The optic nerve and the ophthalmic artery go through the optic canal and into the orbital cavity. This is also known as X-ray Optic Rhese View

Why is X-ray Optic Foramen View Done?

This view is useful in assessing:

• Optical canal enlargement
• Optical nerve enlargement
• Ophthalmic artery
• Optic foramen

Preparation

• Remove any metal components, including jewellery, hair clips, watches, rings, and other things of a similar type, from the body part being scanned in order to prevent a bright or blank spot from developing on the diagnostic film.
• Carefully out whatever objects from the hair, including ear clips, hair grips, and dentures.
• In the event of pregnancy, inform your x-ray technician.

• Position the acanthio-meatal line perpendicular to the plane of IR
