The ultrasound examination of the eye is an imaging procedure for the examination of the retina, the eye socket, as well as for the measurement and control of the eye muscles. It is used in various diseases and to exclude special eye diseases. The examination uses reflected sound waves to create a two-dimensional image of the fundus. In addition, the 20 mHz transducer is used to perform biomicroscopy of the anterior segment of the eye. The examination involves no risks or side effects for the patient and only takes a few minutes.
