Ultrasound biomicroscopy for the assessment of Molteno tube position.
Due to anatomic distortion or surgical complications, it may be difficult to determine the precise position of an implanted Molteno tube. We performed ultrasound biomicroscopy (high-resolution ultrasound) to test the usefulness of this modality in localizing implanted Molteno tubes in 10 patients with Molteno tubes. A 50-megahertz transducer with a penetration of approximately 4 mm was used to produce a magnified image of the anterior segment. The Molteno tube was visualized without complication in all of these cases.
