Scheimpflug- und Topographiesysteme in der ophthalmologischen Diagnostik

Abstract: Modern Ophthalmology is currently experiencing a boom in anterior segment analysis tools that can increasingly gather information with one short measurement. These systems are based e.g. on so-called Scheimpflug (Pentacam, Galilei), slitlamp, and Placido technologies (Orbscan IIz) and other measurement systems. They help in analyzing the cornea in detail, including calculation of corneal wavefront. In addition, morphological and anatomical parameters such as anterior chamber depth, pachymetry, chamber angle, a… Show more

“…The more peripheral corneal thicknesses are considered to be of importance in corneal transplantation 8 and can be used to distinguish between keratoconus and normal corneas 12,[15][16][17] and also in assessments of contact lens-induced swelling of the cornea. 12,18 The present study highlights the need for much further research in this aspect of the cornea.…”

“…The result is referred to as the corneal thickness profile index (CTPI) and is expressed as the ratio between the respective peripheral thickness and the central point thickness. The CTPI is similar in principle to the keratoconus index calculated from either topography data 14 or pachymetry data, 12,[15][16][17] except that in the present study it was systematically applied in a stepwise fashion to all 16 discrete data points along the horizontal meridian of the cornea (excluding the center).…”

“…Die Oculus Pentacam ® (Oculus Optikgeräte GmbH, Wetzlar) ist eines der modernsten Tomografiesysteme zur Vermessung von Hornhaut, Vorderkammer und vorderem Bereich der Linse. Sie bietet eine komplette Darstellung von charakteristischen Kenngrößen für die Hornhaut und eine umfassende räumliche Abbildung des vorderen Augenabschnitts [1][2][3][4][5]. Bei der Pentacam ® wird eine Schnittbildanalyse des vorderen Augenabschnitts unter Einhaltung der Scheimpflug-Bedingung durchgeführt.…”
