Corneal Tomography in Clinical Practice (Pentacam System): Basics and Clinical Interpretation

by Mazen M Sinjab

This book focuses on basics and clinical interpretation of corneal tomography in clinical practice (pentacam system). Tomography is a revolution in corneal imaging. Topography is now used to describe the data generated by placido-based devices from the anterior corneal surface, while “Tomography” is a term given to the data generated from the whole cornea by either slit-scanning technology or Scheimpflug-based technology. This book is divided into 7 sections and 24 chapters, discussing, in detail with many clinical examples, corneal optics and geometry, measuring corneal geometry, screening guidelines, overview for corneal maps and profiles, corneal power maps, elevation maps, belin or Ambrósio enhanced ectasia display, corneal thickness maps and profiles, geometric tomography and corneal topometry, corneal astigmatism, objective corneal dioptric power, astigmatic dissociation, basics of wavefront analysis and measurements, zernike analysis, fourier analysis, factors of false findings, enantiomorphism, practical subjective scoring system, tomographic characteristics of ectatic corneal diseases, grading systems of ectatic corneal diseases, progression criteria, entities misdiagnosed as ectasia, holladay report, and corneal tomography and corneal aberrometry in cataract surgery. This book is useful for those who need some initial assistance in reading and clinical interpretation of corneal topography.
