Echography

Abstract

Echography (also ultrasound) is a clinical, non-invasive imaging module that is used for the measurement of the axial length of the eye and for the investigation of pathologic entities of the chamber angle, the iris and the ciliary body. Furthermore, its role in the management of vitreoretinal pathologies and the differentiation of intraocular tumors is indisputable. Echography remains the first-choice imaging tool in case of insufficient visualization of the posterior segment due to opacity or obstruction of the optical media of the eye. In addition, it can contribute to a more precise diagnostic characterization of lesions in all eye segments. Patients with corneal opacities, abnormalities of the iris, the chamber angle and the ciliary body, as well as patients with dense cataract, vitreous hemorrhage or inflammatory opacities can be properly diagnosed via ultrasound and be treated accordingly.
