ABSTRACT

A number of modalities are now available to assess not only the posterior, but also the anterior parts of the eye. Ultrasound biomicroscopy (UBM) is one of the imaging systems that allow visualization of the anatomy and pathology of the anterior segment. It is particularly beneficial in evaluating regions of the eye behind the iris such as the ciliary body, lens zonular attachment, and the lens periphery that are obscured in other anterior scanning systems. In glaucoma imaging, UBM plays a significant role in the objective assessment of peripheral anterior chamber (AC) angle morphology, which is useful in angle closure glaucoma diagnosis and management. This chapter presents an ultrasound biomicroscopy system for AC angle imaging.
