Abstract
Ultrasound biomicroscopy (UBM) is a recent technique to visualize anterior segment with the help of high frequency ultrasound transducer. It was developed by Dr. Charles Pavlin and Prof. Stuart Foster at the Princess Margaret Hospital at Toronto, Canada in 1989.It is possible to study in detail and to quantify precisely anatomic relations among the anterior segment structures, with acceptable reproducibility.UBM is useful to define a series of measurement parameters that can be used for comparison between normal and pathological eyes. The scleral spur in particular is a very useful landmark presenting a constant reference point for measurement in the angle region.
