Ultrasound Biomicroscopy in Ophthalmology; An Updated Mini – Review

Ultrasonic biomicroscopy (UBM) is an imaging technique that utilizes 50-80MHz high-frequency sound waves to produce a high-resolution image with penetration depth of about 5 mm. It has multiple applications in ophthalmology to evaluate anterior segment structures; cornea, angle, iris, peripheral choroid, as well as foreign bodies localization. The present article is an updated mini-review regarding the use of UBM as one of anterior segment imaging devices, and its clinical applications.
