Clinical applications of Scheimpflug imaging

Expert Review of Ophthalmology, 2009
Since the Scheimpflug principle was first described more than a century ago, there has been great interest among ophthalmologists in the use of Scheimpflug cameras in anterior-segment imaging. Scheimpflug cameras have advanced significantly and modern-day instruments provide comprehensive imaging and topographic data of the anterior segment.

Optimized CorT Total to compare Scheimpflug vs dual Scheimpflug/Placido imaging devices

Journal of Cataract & Refractive Surgery, 2021
Purpose: To compare the manufacturer-provided measures of total corneal power (TCP) generated by Scheimpflug and dual Scheimpflug/Placido imaging compared with corneal topographic astigmatism calculated on the basis of measured TCP data (CorT Total).

THE EXFOLIATION IN THE SCHEIMPFLUG PHOTOGRAPHY

Acta Ophthalmologica, 1988
Abstract. Scheimpflug photography is a very useful method in the diagnosis of exfoliation. It helps to differentiate between tiny subcapsular opacifications and supracapsular appositions. It is a valuable aid in the detection of early stages of exfoliation still unvisible at ordinary slit lamp examination.

Scheimpflug Densitometry in Keratoconus: A New Method of Visualizing the Cone

Cornea, 2020
Purpose: To report an observation made while performing Scheimpflug densitometry analysis on the corneal region affected in keratoconus (KC) that seems to delineate the base of the cone. Methods: Scheimpflug densitometries of 20 healthy subjects and 90 patients with KC were examined.

Measurement repeatability of the dynamic Scheimpflug analyzer

Japanese Journal of Ophthalmology, 2017
To evaluate the repeatability of corneal deformation parameters measured using a dynamic Scheimpflug analyzer and the impact of baseline clinical factors on the repeatability of each parameter.Retrospective, cross-sectional study.Forty-eight eyes (48 healthy subjects; mean age, 49.0 ± 19.5 years) underwent repeated examinations with the Scheimpflug ...

Corneal curvature and thickness – Scheimpflug

Acta Ophthalmologica, 2022
AbstractAlthough the Scheimpflug principle was first described over a century ago, the clinical use of Scheimpflug camera in anterior segment imaging started only a decade ago. Scheimpflug imaging has since advanced significantly and modern instruments provide comprehensive imaging and topographic data of the anterior segment using a noncontact method.
