Abstract:
Optical coherence tomography provides high-resolution images of the anterior segment (AS-OCT). When used as a measuring tool, corneal thickness, anterior and posterior chamber depths, anterior chamber diameter and chamber angle configuration are defined reproducibly. In terms of an optical biopsy by cellular imaging, tissue infiltration, deformation and deposits can be analysed microstructurally. A comparison of pre- and post-operative, as well as long-term follow-up of pathological findings are possible. Examination with AS-OCT is a no-contact procedure, and is well tolerated by the patient. The following instruments were used: Visante-OCT and Cirrus HD-OCT (Carl Zeiss Meditec GmbH, Germany) and SS100 CASIA (Tomey Europe, Erlangen).

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
