title: Image analysis to improve diagnosis of exfoliation.
abstract: OBJECTIVE
  To improve visualization of exfoliation material in standard colour photographs by image analysis.
  
  
  METHODS
  Standard anterior segment colour photographs taken from 17 patients with known exfoliation were subjected to film scanning with a maximum accuracy of 3175 dpi.
  
  
  RESULTS
  Before image scanning, visualization of exfoliation was classified as barely visible in 10 (59%) patients and clearly visible in 7 (41%) patients. After the image scanning, exfoliation material became clearly visible in 13 (76%) patients and could easily be demonstrated.
  
  
  CONCLUSIONS
  Diagnosis of exfoliation material can be improved by standard film scanning.
