Detection of ectatic corneal diseases based on pentacam

Zeitschrift Fur Medizinische Physik, 2016
Pentacam is a rotating Scheimpflug-based corneal and anterior segment tomographer that gives as comprehensive analysis of corneal 3D geometry. With this device the detection of mild keratoconus or ectasia susceptibility is possible. This is fundamental for screening ectasia risk prior to laser vision correction.

Reliability and repeatability of the Pentacam on corneal curvatures [PDF]

Australasian journal of optometry, The, 2009
The purpose of this study was to assess the intra-observer reliability and inter-session repeatability of the Pentacam system (Oculus, Inc.) on the simulated keratometry readings (Sim K) and peripheral corneal curvatures (PCC) at both the anterior and posterior corneal surfaces.One eye was randomly selected from each of the 39 normal subjects from the ...

Pentacam sensitivity and specificity in detecting occludable angles

European Journal of Ophthalmology, 2012
Purpose To assess the sensitivity and specificity of Pentacam measurements in detection of occludable angles and to provide cutoff values. Methods Observational, single-center, cross-sectional study on 64 Caucasian eyes: 28 (43.7%) primary narrow angles or primary angle-closure glaucoma, and 36 (56.2%) controls: all subjects were evaluated and ...
