UBM gałki ocznej Warszawa



Ultrasound Biomicroscopy (UBM) is an ultrasound examination performed with a special transducer that generates high-frequency ultrasound.

UBM allows the examiner to have a close look at the anterior segment of the eye.

It allows the assessment of an angle closure and the position of a natural or implanted intraocular lens.

UBM is used in the diagnosis of conjunctival and corneal diseases, and to monitor the postoperative condition of the cornea and the condition of the iris, to detect tumors and cysts of the anterior segment of the eye, as well as choroidal lesions, post-traumatic lesions and glaucoma.

In cases of suspected glaucoma, UBM of the iridocorneal angle is performed.


Ultrasound Biomicroscopy (UBM) is painless and requires no special preparation on the part of the patient.

The examination is performed in the supine position. The eye is anesthetized with drops and a special eye cup is put on to keep the eye open.

During the examination, a patient does not feel any pain, just fluid flowing over the face.

  • Examination of both eyes takes about 10 minutes.
