What is it?

The ocular ultrasound scan provides a view of the eye’s structures that are not accessible through other conventional tests and examinations, thanks to the ultrasound technique.

The high-frequency waves projected into the eye create reflections that form a precise image of its structure. It is also used to measure the size of the eye and to see any injuries to the structures of the eyeball.

There are two types of ocular ultrasound scan:

  • B SCAN: for the retina, optic nerve and other structures of the entire eyeball.
  • UBM (ultrasound biomicroscopy): for anterior segment structures (iridocorneal angles, iris, crystalline lens, lenses, ciliary processes).

How is it performed?

The test is performed with the patient half-upright or lying down, applying anaesthetic eye drops to avoid any discomfort due to the ultrasound transducer touching the eye.

It is performed with the eyes closed, although the eyes might have to be kept open on occasions.

The UBM-type ultrasound scan (anterior segment) is performed with the eye open.

It must be performed by an expert ophthalmologist in the procedure and in interpreting its results. The images are obtained in real time and in high resolution.

5 keys to the topography

  1. It is a painless test, but does require the application of anaesthetic eye drops.
  2. It is a non-invasive test for patients.
  3. It requires no pupil dilation.
  4. Contact lenses do not have to be removed for any time beforehand.
  5. The estimated duration is 15 minutes.

What diseases can be diagnosed?

  • Condition of the back of the eye (retina) in the event of corneal opacities, dense cataracts or major haemorrhages.
  • In cases of eye trauma or foreign bodies.
  • To assess muscles and structures of the eyeball.
  • To detect ocular tumours and post-treatment monitoring.
  • To track evolution in cases of glaucoma (especially closed-angle) via UBM.
  • To assess optic nerve excavation in cases of media opacification.
  • To prepare for certain surgeries with lens implantation
