Normal Ultrasound Biomicroscopy

Living reference work entry


The ultrasound biomicroscopy (UBM) allows quantitative and qualitative assessment of the anterior segment. It helps us obtain cross sections for morphological assessment of the subsurface of the eye and establish diagnosis in cases where biopsy is precluded. The standard UBM operates at 50 MHz provides lateral and axial physical resolutions of approximately 50 μm and 25 μm, respectively with a depth of penetration of 4–5mm. While dealing in cases with uveitis, one must learn to examine the iris, ciliary body, pars plana and peripheral retina. The chapter describes normal appearance of structures on UBM, relevant to uveitic pathology.
