BACKGROUND: Ultrasound biomicroscopy (UBM) is a high-resolution ultrasound technique that allows noninvasive, in vivo imaging of the ocular anterior segment structures. Before interpreting the UBM images of the diseased eyes, it is essential to understand the structures seen in the UBM image of the normal eye.
PURPOSE: This video is a compilation of short video clips that gives description of identification of the anterior segment structures in the axial scan, a cross-sectional view through the anterior chamber angle region of a normal subject in a radial scan, and identification of ciliary processes in the transverse scan.
SYNOPSIS: UBM provides two-dimensional, grayscale images of the various anterior segment structures and allows all these structures to be imaged simultaneously, in their normal state, as they occur in the living eye. The real-time image is displayed on a video monitor and can be recorded for qualitative and quantitative analysis.
HIGHLIGHTS: The video gives an overview of identification of normal anterior segment structures on UBM. Video link https://youtu.be/3KooOp2Cn30.
