What is meant by "ultrasound biomicroscopy"?

Ultrasound biomicroscopy refers specifically to a high-frequency ultrasound imaging technique that is used to obtain high-resolution images of the anterior segment of the eye. This technique typically utilizes frequencies greater than 20 MHz, allowing for detailed visualization of structures such as the cornea, anterior chamber, iris, and lens. Because of its high resolution, ultrasound biomicroscopy can be critical for diagnosing and managing conditions involving the anterior segment and guiding surgical interventions.

The capability of this technique to produce highly detailed and clear images makes it a valuable tool in ophthalmic diagnostics, particularly for structures that are difficult to visualize with standard ultrasound methods or other imaging modalities.
