title: [Imaging (resolution and quantification) of corneal findings with ultrasound biomicroscopy].
abstract: Important information on the cornea can be obtained by ultrasound biomicroscopy. Intrastromal corneal scars, internal corneal adaptation after penetrating injuries or keratoplasties, corneal dystrophies and other lesions can be demonstrated. The acoustical examination is in competition with optical methods. It has advantages in opaque optical media and in rarely visible regions as well. The cornea is characterized acoustically by three highly reflective layers (epithelial surface, Bowman's membrane, Descemet's membrane) and two zones that are either not very reflective or are only in the middle range (the thin corneal epithelium without internal differentiation and the stroma) in which pathological structures can be seen.
