title: Computerized corneal topography of furrow corneal degeneration.
abstract: OBJECTIVE
  To analyze the corneal topography features of furrow corneal degeneration.
  
  
  METHODS
  Western Galilee-Nahariya Medical Center, Nahariya, Israel.
  
  
  METHODS
  Computer-assisted corneal topography analysis of two patients with furrow corneal degeneration was obtained and studied.
  
  
  RESULTS
  The typical appearance of circumferential peripheral thinning in the lucid interval between the limbus and corneal arcus indicated a clinical diagnosis of furrow corneal degeneration. The corneal topography maps showed central flattening and excentric localized steepening. A step of 1.50 diopters was seen central to the peripheral furrow.
  
  
  CONCLUSIONS
  Keratometry and noncomputerized keratoscopy are insufficient methods of evaluating the topographic features of furrow corneal degeneration. Computer-assisted corneal topography showed steepening and central flattening that may be attributed to the thinned peripheral circumference.
