Evaluation of the Geometry of the Anterior Segment of Postmortem Human Eyes with two Imaging Systems

Purpose: High-frequency ultrasound and anterior segment optical coherence tomography (OCT) systems can be used to obtain non-invasive measurements of the anterior segment. The purpose of this study was to evaluate the geometry of the anterior segment of the human eye using these systems. Materials and Methods: Human eyes obtained postmortem were fixated to special eye holders and underwent anterior segment scanning using a 50MHz ultrasound system with digital enhancement (Artemis, Ultralink; 20 eyes), and an anterior segment OCT (SL-OCT, Heidelberg Engineering; 24 eyes). Four meridians were evaluated in each eye…
