title: [Corneal topography and keratoconus diagnostics with Scheimpflug photography].
abstract: BACKGROUND
  Corneal Scheimpflug tomography is a commonly used non-invasive imaging technique.
  
  
  OBJECTIVE
  This review article summarizes the principles of the technique and recent results from the literature with a focus on keratoconus diagnostics.
  
  
  METHODS
  Review of the literature, own data and expert opinions.
  
  
  RESULTS
  Corneal Scheimpflug tomography allows topography of the anterior and posterior surfaces as well as spatially resolved pachymetry and densitometry. Measurements obtained with currently available systems are highly reproducible but not interchangeable. Combining topographic and pachymetric data allows a highly sensitive and specific diagnostic modality for the early diagnosis of keratoconus.
  
  
  CONCLUSIONS
  Due to the versatility, precision and easy handling, corneal Scheimpflug tomography is the most important imaging technique for the anterior segment of the eye.
