It is beyond the scope of this article to comment in detail on every condition in which ultrasound biomicroscopy has provided useful information. Details of the use of this method in clinical conditions are provided in the references cited. Ultrasound biomicroscopy has given us a new way of looking at disease in the living eye. We can now observe the interrelationships and movement of structures that previously could not be imaged. Future theoretic and technologic advances should expand the usefulness of this imaging method.
