Abstract

The ultrasound in anterior segment has a great number of limitations, despite in patients with ocular cataract or with intraocular lens [IOL], has an important place. Furthermore is useful in patients with iris pathologies [iris tumours], or in patients with malignant glaucoma. The most important technique for anterior segment examination with ultrasounds is the ultrasonic biomicroscopy [UBM] technique, based on 35-50 MHz probes. In the next chapter we describe the UBM examination of anterior segment and its application in different pathologies as cornea diseases or glaucoma.
