Ultrasound biomicroscopy in veterinary ophthalmology – literature review

Abstract

Ultrasonic biomicroscopy (UBM) or high frequency ultrasound (35-100 MHz) is a tool used for ocular imaging. The 4 to 8 mm tissue depth range enables assessment of the anterior segment of the eye, aiding in the diagnosis, prognosis and monitoring of ocular diseases. It is a noninvasive test able to identify different structures of the eye, such as cornea, sclera, anterior chamber, iris, ciliary body, posterior chamber, iridocorneal drainage angle and lens. This review aims to present the use of UBM in veterinary medicine, demonstrating its advantages, limitations and indications in the ophthalmology of small animals.
