Photography of the anterior eye segment according to Scheimpflug's principle: options and limitations – a review

Abstract

Scheimpflug photography and densitometric image analysis are very precise techniques for light scattering measurement and biometry in the anterior segment of the eye. They provide reproducible data on the characteristics of the anterior eye segment in clinical and experimental studies and the set of data obtained allows discrimination of light scattering changes because of ageing, disease or toxic effects. The techniques can also be used to determine no-effect levels or maximally tolerable dosages of physical and chemical noxious factors. Several Scheimpflug cameras have been marketed, but the only cameras commercially available today are the Nidek EAS 1000 and the Oculus Pentacam. This review outlines the development of the technique and its introduction into ophthalmology. Furthermore, the application of the technique in clinical and experimental ophthalmology as well as in ocular toxicology are presented and discussed.

Effect of Pseudoexfoliation on Corneal Transparency

“…[7][8][9][10][11][12] This study has aimed to elucidate the COD in eyes with PEX material, using Scheimpflug photography. We believe ours is the first study about the effect of PES on corneal transparency.…”

Automated keratometry in routine cataract surgery: Comparison of Scheimpflug and conventional values

“…The instrument has several ophthalmic applications, including anterior chamber depth measurement, pachymetry, and keratometry. 1 As a keratometer, the Scheimpflug device can determine several keratometry (K) values according to different corneal measurements. The IOLMaster (Zeiss Meditec AG) is a conventional automated keratometer that measures K values based on the anterior corneal curvature.…”

Normal Values of Corneal Optical Densitometry Using Pentacam Scheimpflug Camera

“…Pentacam Scheimpflug camera is noninvasive system that facilitates analysis of anterior segment and backscattered light simultaneously with automated detection of correct focus and alignment [6,7]. With the generation of colored maps of cornea; topography, pachymetry, anterior chamber depth and densitometry is more simplified than ever.…”
