Ultrasound Biomicroscopy Clinical Database

Ultrasound biomicroscopy utilizes high frequency transducers to obtain high resolution. Our unit, with a 50 MHz transducer, achieves a resolution of approximately 50 microns, and has a tissue penetration of 4-5 mm. Scanning is performed with the patient in the supine position under standardized room lighting conditions. Scanning is performed under topical anesthesia using a 20 mm eye cup which is inserted between the lids and filled with saline solution. In vivo, cross-sectional or transverse images can then be obtained detailing the cornea, iris, ciliary body, anterior chamber angle, and peripheral sclera to demonstrate structural relationships.
