Repeatability of Pentacam peripheral corneal thickness measurements

Contact Lens and Anterior Eye, 2015
To assess the repeatability of corneal thickness (CT) measurements, along the horizontal meridian up to 5mm from centre, in healthy eyes with the Pentacam instrument.CT was measured in 82 right eyes (82 healthy subjects) at 11 corneal locations nominally 1mm apart along the horizontal meridian with Scheimpflug topography Pentacam. Two consecutive scans

Heritability of pachymetric indices using Pentacam Scheimflug imaging

British Journal of Ophthalmology, 2019
AimTo investigate the heritability of corneal thickness at the apex, entrance pupil centre, thinnest point, pachymetric progression index (PPI) and maximum Ambrósio relational thickness (ARTmax) using Pentacam.MethodsThe present cross-sectional and population-based study was conducted in two rural districts that were selected randomly.

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 ...

Pentacam measurements and IOL scattering

Acta Ophthalmologica, 2013
AbstractRigid and foldable intraocular lenses of various materials have shown light scattering phenomena such as surface light scattering and glistenings. The impact of these phenomena on visual function is under controversial discussion. The scattering of light in an IOL can be measured in various ways.

Corneal Density with the Pentacam After Photorefractive Keratectomy

Journal of Refractive Surgery, 2011
Purpose: To measure corneal density and evaluate corneal haze in unoperated eyes and in eyes after photorefractive keratectomy (PRK). Methods: Forty-nine patients (91 eyes) who underwent PRK and 48 control patients (76 unoperated eyes) were measured with the densitometry program of ...

Hornhautbrechwertbestimmung nach LASIK mit der Pentacam

Klinische Monatsblätter für Augenheilkunde, 2009
Zusammenfassung Radienmessungen mit der Pentacam vor und nach LASIK fur Myopie ergaben keine signifikanten Anderungen des kornealen Hinterradius. Die gemessenen Ruckradien waren steiler, als sie dem Gullstrand-Auge entsprechen, was den Unterschied zwischen der klassisch aus dem Vorderradius berechneten Hornhautbrechkraft und dem aus Messdaten in Gauss ...

Repeatability of Oculus Pentacam Metrics Derived From Corneal Topography

Cornea, 2009
To estimate the variability of Scheimpflug imaging measurements over a 1-week period and to determine the impact of age on the measurements and on the variability of the parameters in the study.Three consecutive measurements of anterior and posterior corneal P values (CPVs), central corneal radii (horizontal and vertical), and sagittal corneal radii ...
