title: [Topographical pachymetry and pachymetric topography in circumscribed posterior keratoconus].
abstract: METHODS
  A 29 year-old male patient presenting circumscribed posterior keratoconus in the left eye was studied. After ocular examination, corneal morphometry was studied by a computer-assisted topographic analysis and topographical ultrasonic pachymetry. Corneal thickness profile was represented by a colour-coded map from twenty-five measured points (pachymetric topography).
  
  
  CONCLUSIONS
  Slit lamp biomicroscopy shows a paracentral-localized area of moderate corneal thinning with a nasal-superior concavity on posterior corneal surface. Topographical pachometry and pachometric topography allow to make precise corneal thinning evaluation and offer useful diagnostic data for this rare corneal dystrophy.
