Imagery - ultrasound biomicroscopy and anterior segment Optical Coherence Tomography - in the diagnosis of anterior segment pathology

Abstract

Purpose: The aim of this paper was to show the usefulness of imagery in better documenting the pathology of the anterior segment. Methods: The article comprises clinical cases, insisting on how imagery was essential in establishing the diagnosis or the therapeutic plan. Results: Lack of imagery would have made establishing a proper diagnosis much more difficult. Conclusions: Although clinical examination is simple and offers a fairly good amount of information, some particular cases of anterior segment pathology need additional investigations, every method having its indications and limits.

Keywords: anterior segment optical coherence tomography; ultrasound biomicroscopy.
