Scheimpflug photography

Scheimpflug photography 

An imaging technique that provides an assessment of the anterior segment of the eye in a sagittal plane. The principle of the technique is that the film plane, lens plane and subject plane (plane of focus) are tilted in such a way that all three planes intersect along a straight line. In this condition a subject will be completely in focus. The technique can be used to detect and monitor opacities in the media of the anterior segment (e.g. in the lens), to document these changes and to carry out biometric evaluation (e.g. depth of the anterior chamber, lens thickness measurement) (Fig. S1).

in the current study we evaluated central and thinnest point and 3, 5, and 8 mm pachymetric measurements obtained with a new corneal topography system which combines Scheimpflug photography and placido disk technologies (Sirius System) and atime-domain OCT system (the Visante system) and also evaluated the agreement of the measurements between two devices in different stages of keratoconus patients.
