Ultrasound Biomicroscopy (UBM) is a technique primarily used for imaging of the anterior segment (AS) of the eye. It was first introduced in the early 1990’s by Foster and Pavlin as a way to obtain cross-sections of the eye at microscopic resolution. [1]

Secondary Angle Closure in Pseudophakic Eyes: UBM has also been shown to be of value in elucidating the etiology of pseudophakic pupillary block glaucoma. Pavlin et al demonstrated the findings of pigment dispersion glaucoma with iris concavity, consistent with the hypothesis that iris-lens chafing is responsible for the dispersion of pigment ...

This report summarizes the physics, technology and clinical application of ultrasound biomicroscopy (UBM) of the eye, in which frequencies of 35 MHz and above provide over a threefold improvement in resolution compared with conventional ophthalmic ...

Ultrasound biomicroscopy (UBM) is a type of ultrasound eye exam that makes a more detailed image than regular ultrasound. [1][2] High-energy sound waves are bounced off the inside of …

Ultrasound biomicroscopy (UBM) is a noninvasive imaging modality that enables in-vivo visualization of the structures of the anterior segment of the eye. Unlike routine ophthalmic diagnostic ultrasound which uses frequencies of 5–10 MHz, UBM utilizes ultrasound frequencies in the range of 50–100 MHz.

Ultrasound biomicroscopic appearance of a normal eye. The cornea (C), sclera (S), anterior chamber (AC), posterior chamber (PC), iris (I), ciliary body (CB), lens capsule (LC), and lens (L) can be identified. The scleral spur (black arrow) is an important landmark to assess the morphologic relationships among the anterior segment structures.

Ultrasound biomicroscopy (UBM) is a tool used to image all structures of the anterior portion of the eye using high frequency ultrasound (typically 40-50 MHz). The unique capability of this type of imaging is the ability to view the ciliary body and other structures behind the iris such as the non-central lens and zonules.

This report summarizes the physics, technology and clinical application of ultrasound biomicroscopy (UBM) of the eye, in which frequencies of 35 MHz and above provide over a threefold improvement in resolution compared with conventional ophthalmic ultrasound systems.

Ultrasound biomicroscopy (UBM) is performed with a much higher frequency than the A and B scans and is primarily used to evaluate the anterior chamber angle and ciliary body. Here is a summary of what the different ultrasound scans are used for:
